Boost gas mileage 15-35%

http://www.timebomb2000.com/vb/showthread.php?t=143848

To summarize the above article, adding 3oz. of acetone per 10 gallons of gas will increase your gas mileage.

I added some to my truck today, and it seemed to increase the power a bit, lower the engine temperature, and (based on very unscientific methods) nearly doubled my gas mileage. I couldn't afford to fill my truck completely to calculate the actual mileage. I usually get 10-12 miles from a 1/2 tank (on the guage) to 3/8 tank (also on the guage) driving normally. Today, with the acetone mixed in, that 10-12 turned into 22 miles, and that was going WFO from stops.

I will continue to use the acetone, and report any negative effects (although I doubt any will occur) here.

If you try it, please post your results (before and after mileage). Include year, make, model, engine size, fuel delivery (carberueted/TBI/MFI/diesel), any fuel/air related mods (intake, K&N, exhaust, ski rack on roof, cargo net, oversize tires, etc.), and type/style of driving (city/easy going, city/one of the pedals is always on the floor, highway/55, highway/my spedometer doesn't go that high, etc. Just make up your driving style, but please no "I drive like my friend Tim" :)). I will compile the results in a database so it's easier to see how different cars/trucks/mods did.

To make all replies consistent (easier for me to compile), please just copy and paste the below list into your post.

Also, after you try it, please report your results in the poll.

Here's mine:

After average mileage: <will update when exact figure is availible>

Oh, and I should have added:
Gas mileage is the miles since you last filled up (M), divided by the number of gallons you put in (G). Do not top off the tank, or the results will be skewed slightly. The formula using the above variables, M&G, would be:

Mileage=M/G

The tank must be full from the auto-shutoff on the pump when you begin driving, and full from the auto-shutoff when you calculate the MPG.

Where'd you find this stuff at and how much did it cost...this could change everything as far as my next vehicle :evillol: :evillol:

EDIT: Won't acetone eat away at any rubber parts of the fuel line???

Update:
I searched the internet for literally hours trying to find any negative effects of acetone. It is not nearly as corrosive as ethanol, which all auto manufacturers approve the use of (up to 10%). However, pure acetone will deteriorate neoprene seals over time. The highest percentage mixed with gas that will help gas mileage is .350%, which is far short of 100%. I don't believe this to be a problem (read the article at the begining of this thread) as gaskets, o-rings, plastic parts, etc. will not deteriorate in a 50/50 mix of acetone and gasoline after 6 months. The identical parts placed in 100% acetone, 50/50 mix acetone and gas, and 100% gas all were identical after 6 months of soaking in their respective liquid. I believe the 100% acetone may have deteriorated the seals slightly because the acetone was slightly black in color. But even the 50/50 mix had results identical to gasoline.

B12 Chemtool is 80% acetone (80% is floating around on the internet, and I found no other numbers, although I also found no concrete percentage), and many people use that product frequently with no problems.

I don't believe that there are any problems with using acetone, but I wanted to alert everyone to the possibility of having to replace o-rings. Teflon rings, on the other hand, do not deteriorate at all. Replacing all the stock o-rings with teflon o-rings would still save you money, considering the savings in gas. In all my searching, I found no suggestion of engine mechanical damage.

Oh, I'm sorry, I posted the price/location in the C/K forum where this originated on AF. I got it at Walgreens. A 16oz. bottle was $2.09. It is used as fingernail polish/paint remover. I opted to get the small bottle for easier pouring, but I plan to buy a gallon to refill it. You can find the gallons at pretty much anywhere that sells paint. Seeing that you work at Menards, I'd imagine you'd get it at a discount. :)

Rubber, as far as I could find, is not affected by acetone. Neoprene, which may be affected over time, is what most "rubber like" fuel components are made of.

This forum thing can get confusing when 2 people are posting at the same time :)

Ok thanks...I may give this a try.

so how much would i use to a full tank? mines 88, i think my tank is around 80 litres. right now i barely get 400km's to a tank, whatever that works out to be in mpg. how much is a couple of oz's?

i think i might pick up some of this acetone stuff on my way home tonight.
does it matter what type/year of car?
ive got a FI V6 FWD 1987 Regency, i jsut had a new timing belt and i dont wanna fuck it up. It seems like there are no detrimental effects and ive searched around and havnt found anything bad so... yeai hitnk ill give it a shot.

i just went to my local Omaha Nebraska area hardware store (Westlake/Ace Hardware, i dunno if they have locations in other cities but its basically a much smaller version of menards or home depot) and i bought a 32 ounce bottle of supposedly pure acetone from the paint thinner aisle for about 6 bucks so later this afternoon im gonna fill the tank up and put roughly 6 ounces in. (20 gallon longbed tank) right now, even though the speedo reads 65 to 70 at an actual 60 mph, i think i can roughly get about 10 miles a gallon in the city at normal to slightly slower acceleration rates. its a 350 with a holley carb on top so im hoping the mileage will go up considerably. the only thing really worrying me is that my floats are made of some kind of plastic material and i dont know if they will be "melted" like they would be if i put them in a bucket of carb cleaner. also my jets are made of brass and so is the little carb float valve things that the fuel enters the bowls from. i heard that acetone corrodes brass so im kinda iffy on it. i hope tho that the mixture is weak enuf to not affect em. ill get back to ya all on what happens to it

ClampJockey- 80 Liters is about 21.1 gallons, which would take just over 6 ounces, which is 177.4 mL. So, If I were you, I'd put about 180 mL in a full tank. Free online converter --> http://www.convertit.com/Go/ConvertIt/Measurement/Converter.ASP

L|_|da- It will help in any type of vehicle, but fuel injected engines don't seem to benefit quite as much because they are already much more effiecient than carbueretors.

Jveik- I look forward to seeing how a truck very similar to mine does. Mine's got plastic floats also, and (so far) they are fine. So is everything else. My gas mileage, however, seems like it may have dropped off a little bit from when I first put the acetone in it. It is still probably a 35% or better increase over stock.

I'm a little confused,which is probably rather normal lol, but first you say you bought this at Walgreens(acetone). This nail polish remover stuff has water in it(yes I read the label). I'm having a little trouble convincing myself to add water to my gas tank. And then jveik says pure acetone. Is it? (Yes I'm going to have to read the label). And how did you determine you engine temp was lower? I don't mean to sound like a skeptic but.

The front label on the bottle I got said "100% pure acetone", I hate to say it, but I didn't look at the back label. I'll look tomorrow morning and see what it says. My engine temp is lower because the needle moved (ever so slightly) to the left. I didn't use a raytec to get the tenth of a degree accuracy, so I guess I don't know that for sure, but I have no reason to think my guage is wrong.

I was offroading all day yesterday, and I got miles per gallon, not gallons per mile like I usually get (I was in 4x4 low becuase my T-case jumps out of 4x4 high), so I know the acetone is making a difference.

yeah on that tank that i tried out acetone on so far i have a pretty decent amount over half a tank on the needle guage and ive gone 110 or so miles so far on the 20 gallon tank. usually to get even close to mileage like that i have to be a complete blue hair grandma driver, but on this tank i have been beating the living hell out of the truck for about the first 60 to 70 miles. this kid drove past my house and was causin a ruckus and i had to chase him down lol yeah thats full throttle for about 5 or 10 miles and then heavy throttle for the rest. i also noticed that it seems to have a tad bit more power but not a huge amount. it still has trouble chirping the tires with that posi rear and the turbo 400 that can do 60+ in first gear. basically, the next tank i get ill accelerate about the same as a fully loaded semi truck and see if i can finally get over that magic number of 15 mpg.

a word to the wise. acetone is apparently a neurotoxin and causes dizziness and so forth so between tanks i would recommend keeping the can and the funnel and all that stuff that comes in contact with acetone in a ziplock bag and put it in your garage or at least the bed of the truck NOT in the cab. i didnt get all the acetone off the measuring cup before and i was gettin pretty buzzed before i realized what was goin on so i would definately be careful with that stuff since it sez :eek7: DIRECT INHALATION MAY CAUSE DEATH :eek7: . so especially to u teens out there that sniff the air from whipped cream cans :nono: , dont do that with this crap or for anything for that matter cause u could die from it.

anyways, like i sed right now im gettin roughly ten or eleven to the gallon WITHOUT acetone, so ill see with the next tank what i get.

also for u carbureted guys, if ur mileage completely sucks before acetone, try changing the main jets also. :smile: just make sure its not too lean or it will backfire when u let off the gas at high speeds (engine braking) and i heard a too lean mix can hurt ur engine. i have a holley 1850 vaccum secondaries 600cfm and i put a later opening power valve and jets that were 4 sizes smaller than before and my mileage went up from about 8 to 11ish. so try that too.

this post is getting too long so im gonna shut up for now... ill let u all know what the slow driving tank gets for mileage... :smokin:

Thanks for trying it! Definately don't get that stuff on you, breathe it in, or look at it for extended periods of time without adequate eye protection :). It's hard for me to believe women put that on their fingers in a 5x8 bathroom with the door shut (I guess some men probably do to, don't want to be sexist).

Update on my results:
-Still no problems (not really an update, but good to hear :))
-I put glasspacks on my truck, so my foot is a bit heavier than it was before. I'm going to run through this tank full throttle, then go back to normal driving. I just can't get enough of the roar!
-I went offroading on Saturday, and I think I got MPG, not the GMP that I used to get on the trails. (45 miles from "F" to "E" on a 15 gallon tank, with the 12 mile drive there and back home)

yeah my last tank that i was driving pretty hard with 6 ounces of acetone i got 11.40 mpg and that tank had a chase with full throttle for 5 or 10 minutes plus two separate occasions of 110 mph on the interstate. i think if i take it slow on my current tank ill probly get 12 or 13 mpg out of it which would definately help a lot. also the 11.4 tank was almost entirely on regular city streets with red lights and stop signs. before i would get roughly 11 mpg on a school week tank that includes about 50 to 60 miles of interstate driving, so i have to factor in the fact that that first acetone tank was not including the interstate i usually have since it was a weekend tank. my school tank should run low in a couple days or so and when it does ill fill ya all in on what i got for mileage.

So that will be roughly a 15% increase (with unusual hard driving)... very impressive for a chemical that is so cheap. I am now getting slightly over the gas mileage I did before, but like I said I put glasspacks on. I'm getting used to the rumble now, so next tank I should be able to drive normally.

I looked on the back label of the bottle I got. It has some chemical besides acetone in it (started with a "b"), and fragrence... that would explain the funny smell, almost like burning hairspray (no, I never made a flamethrower from a hairspray bottle and a candle when I was a kid :evillol:). I'm going to give the rest of this bottle to my mom, and use straight acetone from a hardware store.

yeah it seems to have a tit bit more power in my engine with the acetone although the next tank im gonna try putting less in like maybe 2 ounces for 10 gallons to see if less acetone will help even more. i probably wont get huge mileage gains because i already put leaner jets in the carb and its not grummy inside cause i just rebuilt it a while back. however i think even if it only helps out 3 or 4 mpg thats still gonna spank the usual price of gas to make up for that anyday. ill keep an eye on them brass jets too when i rebuild the carb again sometime after i restore the truck ill see if they are all corroded and stuff.

I went storm chasing with a buddy of mine this evening, we were in a hurry, so when we filled up i didn't put acetone in the gas. I noticed a huge drop in power! I floored it to get around a slow car, and the engine fell flat on it's face. I'd forgot it usually does that at sudden WOT :) I noticed the mileage droped off a lot too.

Picked up a gallon bottle at Menards this afternoon, only $12.47 after tax.

yeah i'll be trying this to in an 88 350 chevy with in the next 2 weeks i have run a full tank through a 99 ranger 4.0 liter with about 5 and a half ounces and didn't notice anything i hoping that it will work in the silverado though i'll let you all know

Damn, you guys got me jazzed up on this. I am gonna go buy some right now and put it in. I have always been paying very close attention to my mileage. It's a 97 5.7L Vortec K1500 and I was getting about 12mpg (mixed driving) in cold weather. Last two fill-ups are showing around 13mpg, warmer weather probably helping there.

I am gonna dump in the acetone and see what happens.

Thanks for tips. I think I will also try the "side gapping" mod to the spark plugs; http://www.automotiveforums.com/vbulletin/showthread.php?p=2955589&goto=2955589
but I'll do the acetone first to establish a benchmark, and then do the "side gapping" to see what effect that has on mileage.

Glad to see some posts that talk about improving mileage. These things get crappy mileage and gas prices are going nowhere but up; that's a bad combo.

Menards is awesome!!! I went and checked out this stuff at work the other day and one of my friends put it in his '86 3/4 ton...normally it gets like 8 on the highway and now he's saying an average of like 12-13...

I put in 10 dollars worth today and even though my speedometer isn't working i have noticed from driving about 1 and a half hours that it hardly used any gas so i'm 99 percent sure that its working real well i couldn't really tell a power increase but i didn't smell the exhaust either so i'll get back to you in a couple days with more evidence

Don't forget to read this says to also aid in power torque mileage



http://performanceunlimited.com/doc...idegapping.html

yeah ive gone so far about 155 miles and the needle is still on half a tank. usually i get no more than 110 or 120 miles at half tank. i think i put too much acetone in this time tho so im puttin less in for the next tank.

I filled up the tank on my 98 K1500 and added 7 ounces acetone. I was getting just over 12mpg around town. I have been checking mileage carefully all winter. Will post report on next fill-up.

:rolleyes:

...I didn't smell the exhaust either so i'll get back to you in a couple days with more evidence

If that's refering to my earlier post, that was with the nail polish
acetone. Also, I have glasspacks where the stock mufflers were, so they end about a foot behind the cab, get a bit light-headed with the rear window open sitting at a stop :sleep:. The hardware store acetone doesn't make the exhaust smell any different than straight gasoline.

J-Ri;

Just wondering if you've heard anything bad about it in small engines?

I'd like to try it in my motorhome, but have to consider what might happen to the generator.
Although I would get another gas tank installed just for the generator in a second just for the gas savings

Thanks in advance

I haven't heard anything but i used it in a 7 horsepower lawnmower last week and it didn't hurt it. But i didn't notice it running any longer either but i'm sure you'll be fine the amount of it is so small

yeah i basically think the acetone for the most part works. i got about 12 mpg on my last tank which i only usually get the upper 10's or lower 11's. it also helps just a bit for power. ill post any odd findings like 20 mpg or anything that might happen like that lol

I was doing a little bit of research on this topic, and found this good web site on it

I see that it also works on Diesel, which is good. 2 of the vehicles on my driveway happen to be diesel, plus I run heavy equipment and any savings that the company makes gets returned to me in my holiday bonus if the company can afford them.

J-Ri I noticed that your last coment went missing right away.

Your probably on to something that some people don't want us to know about.

Checked mileage today, after filling up using acetone last week. Right about 12mpg, all local driving. This was identical to previous week, without the acetone. Thus, adding the acetone provided no noticeable difference for me, but I will try again for another few tanks.

I'm gonna do the side gap spark plug mod next.

I had heard that it doesn't work as well with fuel injected engines.

I have been doing some more research on some more forums and I found one person who said they filled up and then put the acetone in and noticed nothing stayed at 17 but then the next tank they put the acetone in and then filled the tank and it bumped there mileage up to 26 mpg. I know it doesn't make any sense but in my 99 ranger i put it in after i filled up and noticed no improvement but in my 88 i put the acetone in and then filled it up and i have noticed better sound under acceleration much better mileage and i can't smell the exhaust 10 yards behind it like i used to be able to. I know that it doesn't make a whole lot of sense but its just a suggestion

J-ri How did you put it in there, you said it worked for you

chevy-ss How did you put it in there you said it didn't work

Yea... my last past went away pretty quick... I was thinking hydrolysis in the vehicle powered by the alternator, but after researching it, I found it would require in the neighborhood of 1,000 amps continuously (at 12v) to provide enough hydrogen just at idle. Perhaps some chemical would make the hydrolysis more efficient (I know soap helps a bit, Chrysler was trying this a few years back, but I heard about it once, then never again. I wonder if maybe oil companies are trying to keep these things quiet :uhoh:) I'm going to play around with a 5 hp engine, an alternator, and a hydrolysis tub this summer and see if I can get it to work, but I don't think it's possible... it just takes more power to produce hydrogen than you get from it. That makes hydrogen production from petrolium products impractical, but with a wind generator or a solar panel, it would be great.


biglogonafrogbig-
To add the acetone, I just fill the tank, then put in 3 oz for each 10 gallons. from now on, I'm going to add about 1/4 gallon gas after the acetone just to wash it out of the filler tube. Might be better to not have pure acetone just sitting on the hose. I've heard a few people with vortec engines say that acetone doesn't make a difference, I'd imagine Chevy-SS has vortec heads in his truck.

Folks, I hate to spoil the party but adding acetone cannot increase the engergy of your fuel.

Gasoline is made up of hundreds of different hydrocarbon compounds from butane all the way up to dimethyl naphthalenes.

Now those of you who were paying attention in CA when the phase 2 gasoline came in, the gas mileage on the cars experienced about a 10% decrease in fuel efficiency. Why? Because when CARB (California Air Resources Board) changed the rules on the refineries, the product that the refineries sold in CA was a shorter run distillate with decreased concentrations of the larger molecules (more energy).

So adding a low energy compound such as acetone to your tank cannot give your fuel more energy.

What it CAN do is help clean out the crud that accumulates in old engines. So perhaps what you are experiencing is acetone cleaning the engine intake ports and such which would give you better gas mileage. But a well tuned & clean engine will not see an increase in fuel economy with acetone added.

What your saying may be true but i believe that it has definately worked for me whether it cleaned the engine or let more of the gas burn, but if it cleaned up the engine i don't think i would have noticed any results as soon as i did which was about 30 mins.

Hey, it's great that there is a scientist here. Thanks for the info. Can you offer any suggestions for an additive that may actually help mileage? Do you have any other mileage-improving suggestions?

Personally, I think the auto manufacturers should be absolutely embarassed at the horrid mileage most vehicles are getting. This is a common topic of debate at many places I hang out. A lot of people (including me) think there must be some sort of collusion going on between the gasoline-producing companies and the auto manufacturers to keep fuel mileage at this abysmal rate.

Would it be better than any fuel system cleaner that you could purchase off the shelf at (insert favorite auto store here)? Milage isn't that big of a deal for me :)

An automotive engineer would be better to ask. All I can comment on is the physical and chemical properties of the fuel.

But common sense says that in order to increase efficiency, I either have to improve the system or improve the fuel. You can add the Octane Boost stuff (basically just refined diesel) and what you are doing is adding heavier hydrocarbons so basically throwing larger logs on the fire so to speak.

Decreasing the weight of your vehicle will help improve fuel economy and the reverse is true.

There is no "collusion" between oil comps and auto manufacturers. No more than between doctors and pharmaceutical companies keeping us hooked on drugs rather than healing. Hogwash.

Automotive engineers are professionals. They make the best car possible given the limitations. And there are limitations you know.

Well one possibility is that the oxygen in acetone adds needed oxygen to improve efficiency of burning if your fuel air mixture is running rich. But I am skeptical even with that. Although that is more understandable than increasing the energy of the fuel which is a physical and chemical impossibility by adding acetone to gasoline.

Yes folks. You heard me right. Everything is NOT possible. Whoever says otherwise is just being argumentative or silly.

Greetings Fellow Truck Enthusiasts,

I'm intrigued but not confident by the idea of acetone being added to the fuel system.

Just so you understand - acetone is what is used as a "cleaner" and "cure stopper" when doing fiberglassing. When making a fiberglass project and your hands get full of the fiberglass resin/hardener - your hands heat up and start "curing". Acetone is used to stop the cure - cool down the heat buildup of the resin hardening - and clean hands and surfaces of the resin.

Acetone's flash point and flame volatility is very flameable and explosive when exposed to spark or flame. Different than gasoline - it has more fast evaporative cling to it. It also can effect paint, bedliners and other surfaces. I'd urge caution around this stuff. I've worked with it often in various projects. Pure acetone has little smell to speak of - its clear - and very inhalant oriented (much more than gasoline).

For those interested in saving gas or improving engine performance - you might try this link to many different reader provided ideas.

White Lightening

Acetone doesn't increase the power in the gasoline. It allows the fuel to atomize more completely. There is a link in the very first post that fully explains this.

And yes, it's not good to get in on you, inhale it, or to get it on paint or plastic. You also shouldn't drink it, use it as eyedrops, or light a cigarette while pouring it. Be careful with it.

Oh Shoot, there goes all the fun of buying Acetone! LOL.

I just about have my boss convinced to try using it on some of his old equiptment. I'm curios how much longer a machine will run with it added to the tanks.

Even a 20% increase is still 1 free day a week per machine 100+ gallons of fuel per machine a day really adds up

I don't think thay he'll try it on his 2 new trucks unless it really seems to work without any problems

I don't feel comfortable messing with the Dodge, what with the fuel injection, sensors and computer and all. I'd hate to screw up something that I can't fix myself. I'm familar with the Torino having re-builit the engine 2 years ago and restored the body, interior and had the top replaced.

I look forward to hearing your results, But when you fill it i would put the acetone in at about 1/4 of the tank and then put the rest of the gas in, I heard that doing that can be the diffrence in it working or not working.

I have no way to back that up but i was just thinking that someone told me once the gas stops to not top it off because theres a chance that some gas could evaporate. So if you put the acetone in at the end becasue it evaporates so quickly that it just leaves. Although i doubt it, but just a suggestion

Hi, John M here, Sounds good to me. Probably will let everything mix more fully than adding the acetone to a full tank. Sure hope it helps. Gas prices here in Tampa, Fla hit $2.29/gal for reg unleaded this morning. It was $2.15 just 3 days ago. Guess I should have filled up both vehicles then!

John M again-have you ever heard of a Water Injection system used in the early 70's during the gas crunch. It used a glass bottle to hold water and a vacuum line with an adjustable valve going to the base of the carb. It fed a water vaper into the intake and cooled something down which ended up in 1-2 extra miles per gal if I remember right. I wish I could remember more about it. I read about it in Mech. Illustrated I think.

I look forward to hearing your results, But when you fill it i would put the acetone in at about 1/4 of the tank and then put the rest of the gas in, I heard that doing that can be the diffrence in it working or not working.

Well, I did it. I might have screwed up though. I side cut a spare set of AC plugs I had, Indexed them(at least 6 out of the 8), filled the tank and added 6 oz. of Acetone. I have driven 112 miles(all city-low speed-30-40 mph). Filled up at the same station, same pump, same octane, took 12.6 gal. Averages out to 8.88 mpg. Where I think I may have screwed up, the AC plugs I removed were the expensive AC answer to the Splitfire plugs. I forgot that I had put them in last year. I'm going to run these plugs for another week or two and monitor how they do and then change the plugs back to the expensive ones(I forget what they call them)I'll keep using the Acetone. I also have a homemade Water Injection system that is supposed to help fuel economy but I'll wait to install it for a few weeks. Wish me luck. John M.

Did you fill it up and then put the acetone in or did you put the acetone in and then fill it up.

Did you fill it up and then put the acetone in or did you put the acetone in and then fill it up.

I had about a quarter of a tank, put in the 6 oz. of Acetone then filled the tank on top of the Acetone. It should have gotten well mixed.

Hmm, i don't know why it didn't work then maybe it just doesn't work with your engine. But you said something about it being old spark pluggs in it i don't think that would make a difrence but i was thinking we tried it in my dads 99 ranger and it didn't work but his plugs are real old 93,000 miles still original plugs. But in my 88 chevy i just replaced the plugs and my mileage seems to have doubled but i can't tell for sure the odometer doesn't work. I need to get a gps unit. So i guess you can try it again with the new plugs and hope for the best

Also any one else that has tried it, how old are your plugs

looks like i mis read you didn't say they were old. But if you tried that side gapping that could of been hurting more than helping, it sounded like a good idea but i tried it on my 7 hp lawnmower and it made things worse it kept backfiring when cranking and it just didn't run as good I know it could work diferent in a truck

The plugs I side gapped were almost new, only 3 months wear on them. (I have never side gapped plugs before, never even heard of it until someone here on this forum suggested it.)They are also AC plugs, AC44ts. I use them as a troubleshooting tool to eliminate plugs as a source of a trouble if I am having a problem. The normal plugs that I have been running are AC-2. They have a different shaped center element and cost about 4 times as much as a regular plug! I used to use Splitfires in my 62 T-Bird and was really happy with them. I think I'll try them next on the Torino.

would this quarter of a percent of acetone technique work for a guy with an 89 camaro with an L03. Which is a 305 TBI with 140000 miles. I get about 17-18 if a take it easy which isnt bad i guess but more is better ya know. Im also rebuilding a 73 c-10 with the original 307 and only 70000 on it. its rusted out pretty bad but replacement panels are pretty cheap and i think i can do it. But anyways, the camaro, will it work? I can have this stuff eating out my throttle body. Thanks

I can't guarantee to you that it would work, but it is always worth a shot and i've used it with success for 3 tanks and I have not noticed any eating out of the throttle body so i pretty sure that it would be fine, just remember to only use about 2-3 ozs per 10 gallons. Good luck
