Gas additives

I have a '99 5.3 C 1500 I recently purchased with 83k miles. I add 8 0z. of 100% acetone from HD with each tankfull of regular. I'm getting over 20 mpg around town and about 26 on the Interstate. Whadaya think?

I think you're gonna end up blowing something up!!!!

I think you're gonna end up blowing something up!!!!

no, i've heard of adding acetone before, but I've also heard that it won't do squat for a fuel injected vehicle... Ozbo, i'm not trying to be an ass, but is there any proof of this?

I've heard of somme additivews being bad for the materials in the fuel system and can cause some damage. But then if I'm wrong on this one, at least it'll clean the finger nail polish out of the injectors!!!

Hey,
I just found a couple of articles on this... This dude may have something here:

Yeah the things stated in that kptv article are why I have yet to try acetone in my tank.all that shit get expensive if you have to start replacing it.

Yup...the same thing was happening in '80 when they first came out with gasahol. It was eating at certain parts of the carberators. They stated using materials that could stand up to the alcohol at about that time. I suppose that if the acetone thing catches on, they can do the same thing.

i would steer clear of it myself. sounds like to many risks involved from what i read on it. i looked into it a while back and looked really bad for the motor, especially on my nice truck. if i had a cheap work car i would try it and see what happens but i dont.

There has actually been quite a bit of discussion on acetone on this forum in the last 6 months or more. For me - I'll not put it in my tank - if you've used Acetone in other activities - you'll quickly notice how it "cleans" surfaces - it strips off oil, lubricants, etc.. It is a great cleaner - but "it goes to metal" so much - that I wouldn't want it around my metal or around rubber parts. Everyone needs to do their own thing :smile:

I experienced near 25% gain from Berryman's B-12 additive, and I noticed that it contains Methanol, acetone and a bunch of other good stuff like that. From what I can tell from articles and such, in small amounts it helps atomize the fuel at the injectors. I dont think I would add straight acetone to my gas though :headshake

PS The good thing is that B-12 costs only $2.39 for 15 oz. (2 cans per tank = $5)

From what I read, you only add 5 oz to your full 25 gallon tank...thats not hardley enough to hurt anything cosidering how much the fuel will dilute it. I'm thinking about trying it and seeing whats up with it on my trip to Statesboro this weekend.

Actually Berryman's B-12 and the SEA-FOAM (c) brand recommend about 1oz. per gallon. So 2 cans treats 30 gallons. (In my case 25gallons). I tallied up my MPG today after a fill up, and I had 16.7MPG this last tank on 87 octane with 2 cans B-12, which is up from 13.7MPG with no additive.
NOt bad eh??

EDIT: I just realized you were referring to acetone. You are braver than me!!

I've read some more on it now, and I'm trying it if I can find the acetone. I'm going to add 3 or 4 ounces to a fresh full tank of gas before I leave Thursday afternoon. If it braks something, hell, I'll be stranded in the same town that my g/f is in right now....I can't lose.

I've ran several different mixtures in in numerous tanks of gas. The most beneficial being 6oz in 26 gallons of gas. My normal pure 87 octane would get me about 325 miles, with the acetone mix it got me around 340-350. Whoopidy doo!!! I have tried close to 25 tank fulls and have had zero adverse effects but then alsom IMO no MPG increase to wanna bother with it anymore. I have been told it will do little more than nothing to fuel injected vehicles. However a buddy of mine has and old K30 blazer and he claims he get an extra 75 miles out of his tank while acetone. But all in all i'd say no additive will give enough extra miles to make it worth while.

I had a small bottle of it at my house I found last night, so I'm trying it. I already have it measured and waiting for the trip.

But all in all i'd say no additive will give enough extra miles to make it worth while.

13.4 MPG No additives 87 octane
16.7 MPG B-12 additive 87 octane

25 gallon tank means I averaged 82.5 extra miles out of a tank of gas

Divide that by my old MPG (base) 82.5/13.4 = 6.156 extra gallons "I didnt have to buy"

6.156 gal x $2.89 = $17.79 - ($5 cost of 2 cans B-12) = Total savings of $12.79

Not a bad deal. lets say I only save $10 per tank for a year average, $520 savings for a year. :naughty:

Unless I didnt calculate something right, I would say that even a slight increase in MPG can add up. It all depends on how much you buy the additive for. IMHO Berryman's B-12 is the cheapest and has the cleanest mix of methanol and acetone in a metal can you can buy. Heck If I were serious enough, You can buy the stuff by the gallon for an ever deeper savings.....

I have been experimenting with water/vapor injection on my 5.3 for the past 2 weeks. I set up a system that hooks up to the vacuum hose on top of the intake and bubbles through a jar of water. Stock, I was getting 13.5 in town, and 16 on the highway. now I am getting 15.5 - 16 in town, and 18 to 22 on the highway.

By the looks of the bottle, not much evaporation is happening. I put a quart of water in the bottle, and after a week of driving, it looks like over 3/4 is still there.

I am going to give it a try for another weeks and see if it continues to help.

Now how does that work? Pics would be nice, also

Now that is something I'm not trying. I don't like the thought of water in my engine...thats what blew my other one up.. a leaky head gasket.

And where do you get berryman's B-12?

I dunno? I was kind of wondering the same thing.

And where do you get berryman's B-12?

Here's what it looks like. You can get it at autozone, walmart. It's been around for years. I wouldnt order it from the net. I would get it locally to save on shipping.

15oz can http://www.midwayautosupply.com/detailedproductdescription.asp?3023

case 15oz cans (12)http://www.midwayautosupply.com/detailedproductdescription.asp?10031

1 gallon can http://www.midwayautosupply.com/detailedproductdescription.asp?3021

EDIT: They also have what they call "Fuel injector cleaner" In a plastic bottle. Do not get it. It has less acetone and methanol. The metal pour cans are what you want. It also costs less. And it can be used regularly.

I added 3.5 oz of acetone to 23 gallons of fuel yesterday, so we'll be seeing what the deal is in the next few days. I hope it dont mess up anything. I do know that the acetone is some strong stuff!!!

ANd you can put that right in your gas tank? And there are directions on the bottle for doing that?

Yep. It says can be used to treat 8-25 gallons of gas (about 1 oz per gallon it says). It can be used regularly too.

So far, I have just above a half a tank, and I've been 270 miles. I guestimated it at about 24.5 mpg so far. that was averaging about 75 mph.

1500 bucks for a fuel pump replacement alone, seems penny wise and dollar foolish

I would never pay $1500 for fuel pump replacement. Who charges that much?

I'm just curious. Have you ever filled your tank at the quarter, half and three qtrs tank mark just to see what it takes? On mine, it'll take about 14 Gal dead on the half mark, which for me would read at about 20-21 mpg just before the same. Still, that's pretty good. I filled my tank and put 8 oz. acetone in mine yesterday. I should have a report by the middle of next week, but so far it's realistically looking like about 20-22 mpg. I'm keeping my fingers crossed.

I believe it so far. I want to start buying this stuff in gallons if I can find it.

Anyhow, I'm impressed so far. I'll see how long this tank lasts.

You are trying straight acetone right? Where did you get it? Is it 100% acetone?

You can find it at Wallgreens or any drugstore. You can also find gallons at hardware stores. Look on the bottle and make sure it says 100% acetone instead of having other things added to it.

I got a gallon and the OSH Hardware store and put 8oz in a full tank (the recommendation is no more than 3 oz per 10 gallons). It was in the paint section next to the paint thinner. So far my first trial is looking really good. It reads 140 miles in the gas gauge area where I usually show about 110-120 miles. Sweet!!!

I am now wondering if the real problem here is that we ALL need our injectors cleaned and if the acetone and ChemTool are just doing a good job of cleaning the injectors

I don't think so. I've been using injector cleaners since I've had the truck. Lately I've been using Lucas. However, I hadn't tried Berryman's, but from what I understand, it has Acetone in it. Using the straight Acetone is a sorry sight cheaper than Berryman's. It cost about $.87 a tankful at 8oz/tank with the straight Acetone bought by the gallon which will treat 16 tanks of gas and like I said so far it's looking really good, whatever it does!!!!

I concur. I drive around town last night, and still have half a tank, and almot 300 miles on the odo.

So would it help to "Clean" my injectors if I have 1500 miles on my engine????? J/K :slap:

I'm running lucas in mine right now... I want to see if it does anything, but I don't think it does squat

I've used that Lucas stuff before, and I haven't seen anything at all from it. Oh yeah BTW, Auburn is winning...I'm pissed.

Another thought on that is according to the article (I'll post the URL below) the Acetone helps with evaporation which helps the fuel to burn more effeciently. Another thing it said was not to use too much as the effectiveness will lessen and yes it does help clean the injectors.

Sorry

I am showing 200 miles with 5/8 tank left!! Hooah! The berrymans also has methanol (very small amount) to help with the fuel atomization. It breaks up the surface tension of the fuel droplets and lets them turn into a fine fog, instead of a spray with coarse droplets. I think it is definitely helping. After one more tank treated, I will run a tank untreated and see if I have good results.
