Acetone Fuel Additive Update

I need to add a little science to this discussion if I may.

As far as my credentials, I have a Ph.D in physical organic chemistry from the Univ of Illlinois, at Champaign-Urbana (a serious school), and I have worked in the chemical industy and oil industry for over 20 years. (Yes, I'm an old fart).

There are a few facts here have have been either ignored or glossed over.

Fact number one: Acetone is more dense at 25C (room temperature) than gasoline. That means it will sink if not dissolved, not float. There is no planet in the solar system in which acetone will float on either iso-octane, octane, heptane, or hexane, the properties of which are the best approximation of gasoline for which I can easily find numbers.

Here are the densities of these materials at 25C from:

http://www.simetric.co.uk/si_liquids.htm

and the Merck Index, 10th ed.

If someone had bothered to look these numbers up, they would find the same thing, since everyone seems to agree with these numbers to this precision.

Density in g/mL at 25 deg C

iso-Octane 0.69190
Octane = 0.7028
heptane = 0.67950
hexane = 0.65483
Vehicle gasoline = ~ 0.74
Acetone = 0.78458

Gasoline is a mixture of things and has a density of around 0.74 g/mL (according to the link above), but there is no real number since formulations vary.

The greater the density, the more something will tend to fall to the bottom of a mixture.

The second fact is that it really doesn't matter what the relative densities of acetone and gasoline are, because they are very soluble in one another. Acetone is very soluble in these hydrocarbons, and even more so in aromatic hydrocarbons (for example toluene or benzene). It is considered miscible in most aliphatic hydrocarbons ("miscible" meaning soluble in all proportions - never able to separate) like hexane, heptane, iso-octane, and octane. That makes it a bet-your-ass sure thing that it will dissolve in gasoline totally at the concentrations that are proposed for its use in gasoline, since gasoline, with it's aromatic hydrocarbons and other additives, is considerably more polar than the pure hydrocarbons that are useful for comparative purposes.

I have a proposal for anyone here:

Take a camera and some pure-as-possible acetone and gasoline and show the two in separate glass containers in any proportion you want and then take a picture of you mixing them, then stirring them, then the end result. Post the pics. Unless there is water in the acetone, the result will be a clear solution that will never settle or separate.

Finally, from my experience in running reactors sealed with O-rings, the low level of acetone in the gasoline, as proposed, will not harm gaskets or O-rings unless they are made from something extremely sensitive to acetone, like polycarbonate (which is ridiculous). The activity of the acetone at these concentrations is 1/500 less than pure acetone (6 oz in 19 gal).

This last discussion is my opinion, but an educated one and worth considering.

There ya go guys. I don't think there is someone more qualified in this thread than Brian.

The proof is in what he said. I was not trying to pull the wool over your eyes at all.

theres always some water in acetone, i thought. or are we talking about industrial strength. LT, were you using paint thinner/ laquer or just plain ole nail polish remover? brian, thank you for clearing up things for us.

I used 100% Acetone.

I used 100% Acetone.
I looked into it and the best I could find was at walgreens, 100% pure acetone, no water. It did say one of the ingrediants was fragance. So yes I gave in and bought some, have not used it yet, but if I do at least my ehaust will smell pretty!

On a little bit of an off topic note, if anyone here rides a sled and had a polaris with a VES engine you will know what I am talking about. You have to use polaris VES oil to keep the valves from sticking. Well Polaris comes out with a new and inproved VES2! Wow cool ha? Not so cool............ the only difference between the 2 different 2 stroke oil is that in the VES2 there is one more added ingrediant....... ready for this one.... VANILLA! They added vanilla to make the exhaust fumes more pleasent! And it is another $7 dollars a gallon more! Just throwing in a little off topic. I will let you guys know if I use the acetone in my truck.

Completely fine.

Remember, 3 fl.oz / 10 gallons.

You're welcome

All acetone has water in it, even the 100% acetone, it is just a matter of how much. If there is 0.05% water, then the acetone will solubilize it and there is no problem. If there is 5% water, the acetone will not be able to dissolve it and you can't use it in gasoline.

Batches of acetone are totally unpredictable, as far as water content goes (acetone sucks water from the air), so:

1. Buy a large container and use only acetone from that container. A gallon of reagent-grade acetone would be best (from Aldrich Chemical Co.) in a glass bottle as provided. Anything less than that is suspect for water content. If you don't want to pay alot for the acetone from Aldrich, search for unscented 100% acetone and only use it. The scent may cause a problem with your sensors - which you don't need.

I would test it by adding quite a bit to some hydrocarbon (hexane, gasoline, whatever) maybe 10:1 (hexane:acetone) and make sure it forms a colorless clear solution. If the mixture becomes hazy, then don't use it. Throw it away or return it or give it to your girlfriend. It has too much water in it.

2. Never pour acetone back into the container. Once it has been poured out, throw it away or use it immediately.

3. Test the acetone in the container periodically (once a year) as I suggested above, or some other test like that.

4. Don't buy acetone in a plastic container. Acetone will absorb water through the plastic and be wetter than that in a metal or glass container. Also, the acetone will leach some impurities from the plastic container and they are not what you want in your gas. Play it safe. You don't know how long it's been since the acetone was bottled. It may have been kept on the shelf for years, being opened by other customers to smell it or something.

5. Make absolutely sure that you keep the container tightly closed, or transfer the acetone into a really good container (glass is better than metal or plastic) with a good seal and keep it well closed always. If you accidentally leave it open or loosely covered overnight or you don't know how long, test it again before you use it.

More like a pretty lavender :rofl:

I think using scented acetone is a bad idea.

I think using scented acetone is a bad idea.

True, but the concentration is probably close to nil.

It's your vehicle.

It's your vehicle.

You do have a point though, with all the acetone options out there, try to get the unscented one.

I can't believe I am saying this....... LMAO!

Well I picked up one bottle and it had vitamin e and other stuff and started cracking up. People were looking at me funny when I was asking about the acetone and saying I needed it to be a pure as possible. I bet they were saying yea he has a METH lab at home and is trying to find something to cut it with... ;) you never know!

Anyway, I bought a trial quart of acetone from Home Depot and I am going to try it in my truck starting today. The can I bought is handy in that it has a small plastic snap spout - easy pouring. I will try 6oz/tankful, maybe 8 oz/tank if I only see a small effect. I will post back. My truck is very consistent at 16 mpg since I've owned it. I have also tested mileage from various brands and none that I tried (Shell, Amoco/BP, Chevron) seem to give any better mileage than the others.

I found a gadget at Advance Auto Parts which is a syringe with graduations up to 2 oz for metering 2-stroke oil. I also bought a small funnel for the tank. What I did was take the plunger out of the syringe and fill the syringe from the can, keeping one finger over the opening to keep the acetone from falling out the bottom. Then I placed the syringe over the funnel and released my finger and the acetone all went in the tank. Acetone evaporates so fast, the syringe (and my finger) were dry before I put it back in the truck.

If this has an effect, I will be tempted to try MEK, which is very similar to acetone in chemical structure. I wonder why no one has ever mentioned trying MEK?

How big is your tank?

also, reset you computer by pulling the negative battery cable for 15 minutes so the computer will relearn faster.

Good luck

Also, MEK is not as available as Acetone.

18 gal. I will reset the computer. Thanks for reminding me.

I thought I saw MEK at Home Depot.

Hi Brian, I’d like to ask you some questions that you may not know the answer to. It is not my intent to launch a personal attack or to challenge your credentials. My sole purpose is to simply ask questions in an effort to educate the folks on this Forum.

Question 1. If Acetone is as good as is being claimed and is as not harmful to our vehicles, then why hasn’t anyone the petroleum industry added it to their fuel?

Question 2. What is the tolerance on the amount of Acetone used in a vehicle? What is the ideal mixture or concentration? We’re hearing 3 oz. per 10 gallons of gas, what happens if 2 ounces is used or 4 ounces, and the big one what if someone dumps a whole gallon of the acetone into their tank. (Remember, we’re dealing with people that don’t know better and think that “MORE IS BETTER”). Is there a “PEAK” to the positive effects of acetone, meaning at some point, higher or lower than the recommended amount, are you nullifying the affect that the acetone is suppose to provide?

Question 3. Has General Motors or anyone in the SAE ever recommended or discouraged the use of Acetone in fuel?

Question 4. How did you learn about adding acetone to your gas tank? By reading this Forum or was this a little well known secret that generally known around the industry etc.?

Question 5. What other additives and chemicals are out there that could potentially improve a vehicle’s performance, and maybe increase gas mileage? I know you already have mentioned MEK.

Question 6. What other chemicals and additives are out there that should be avoided that would do harm to a vehicle? This question is particularly important because there are people out here that I swear will dump anything into their gas tanks simply by reading something on the internet.

Thank you for your reply and I’m waiting to see your answers to these questions.

I'm as skeptical as Rick. If this "wonder additive" has seemingly all these positive effects (+mileage, +part lifespan, -$) with no negatives it strikes me as odd that the petroleum industry would not add it.

I had a bit of time on my hands one day so I read through the thread above and cross referenced the "statistics" with a Canadian website that hosts "The One Tonne Challenge" (Canadians will have heard of this one).

In a nut shell, if acetone was true to at least the minimums of the positive effects that are being claimed, were it used in gasoline Canada could meet about 2% of their Kyoto commitment.

Question 1.
If Acetone is as good as is being claimed and is as not harmful to our vehicles, then why hasn’t anyone the petroleum industry added it to their fuel?

I can't speak for the petroleum industry and I can't speak for any effect acetone has on gas mileage. I just decided to try it for myself and you can be sure I will drop it like a hot potato if I don't see a measureable increase within 3 or 4 tankfuls.

In answer to your question, if I were a sceptic (which I am) I would say they will sell more gas and make more profits without acetone. Just an guess/opinion. Also, they couldn't really make any claim about increased gas mileage since not everyone reportedly sees a mileage increase.


Question 2.
What is the tolerance on the amount of Acetone used in a vehicle? What is the ideal mixture or concentration? We’re hearing 3 oz. per 10 gallons of gas, what happens if 2 ounces is used or 4 ounces, and the big one what if someone dumps a whole gallon of the acetone into their tank.

Is there a “PEAK” to the positive effects of acetone, meaning at some point, higher or lower than the recommended amount, are you nullifying the affect that the acetone is suppose to provide?

All I know is what I've read in the article quoted elsewhere in this topic. Apparently, different engines have different requirements for acetone concentration (when it helps at all). I plan on trying more and less than 3 oz/10 gal and that's about all the time and energy I'm going to give to this experiment.



Question 3.
Has General Motors or anyone in the SAE ever recommended or discouraged the use of Acetone in fuel?

I have no idea.


Question 4.
How did you learn about adding acetone to your gas tank? By reading this Forum or was this a little well known secret that generally known around the industry etc.?

I first heard about it in this topic, and then read as much information as I could easily find. It was no secret that I found out. The negative side of this is that 90% of what I've read is written by or quoting one guy. The postive side is that he doesn't obviously stand to gain by pushing acetone (he doesn't sell acetone for a living) so I don't see a conflict of interest in his giving this advice.


Question 5.
What other additives and chemicals are out there that could potentially improve a vehicle’s performance, and maybe increase gas mileage? I know you already have mentioned MEK.

I don't know of any others.


Question 6.
What other chemicals and additives are out there that should be avoided that would do harm to a vehicle? This question is particularly important because there are people out here that I swear will dump anything into their gas tanks simply by reading something on the internet.

I would avoid putting anything in my vehicle that isn't approved by the manufacturer. Acetone is an exception because I can't figure out how trying this can do any harm - at the concentrations I will be using.

Just think of it like this.

Would McDonalds put something in their food that would have you consume less of it?

If you know corporations, you know they would never do that.

Well, in a sense I guess they would or they might. Why does Chevron and a few others add all of the xylene, toluene, and who knows what other chemicals and solvents to their fuels? Well, those are just solvents that keep things clean, right? But by putting those additives into your gas, your engine runs better than if the additives were left out, and thus you use less fuel. Are these additives a result of EPA regulations? I don't know, but I can tell you this, there are a number of municipalities and communities around the US (not sure about Canada) that do not meet or at least have trouble meeting the strict air pollution standards. Phoenix is one of those cities, especially in the winter months. The laws are getting tougher and tougher every year to pass and I still gotta think one of two things, either the acetone has some serious drawbacks or it is in its infancy and yet to be explored, because if it is in-fact as good as is being claimed, we'd be seeing it introduced into our gas stations at least during certian times of the year like we do with the various blends of gasoline currently sold in Phoenix now. We get MTBE mixed into our gas during some months and Alcohols mixed in during the other months.

I don't know how the oil companies think or how much clout the EPA has with the people who are responsible for formulating gasoline, but I would expect that the companies get together as a group and meet periodically to discuss these issues. If acetone were useful for increasing mileage, it would be in their best interest to repress it across the board. If one used it, they would pretty much force everyone to use it and they would lower gasoline demand in doing so.

I deal with industry (not oil) on a daily basis from the government standpoint, and they do talk among themselves, and they do stick together against the government and in direct conflict with the public's best interests and the public health. It is obvious to me from the decisions they make and the positions they take on important regulatory issues, that what they care most about is pleasing their stockholders by increasing profits, and thus keeping their jobs. They spend a significant amount of time worrying about what not to tell the government.

For what it's worth.

I don't know, but I can tell you this, there are a number of municipalities and communities around the US (not sure about Canada) that do not meet or at least have trouble meeting the strict air pollution standards.

I would say that the toluene and xylene are not additives. They are natural constituents of the crude oil and thus the gasoline, and the formulators have no choice but to include them. As a matter of fact, the sweet Pennsylvania crude that made Pennzoil famous was prized for its high aromatic content. It made the distillation fractions very good solvents for additive packages and particularly sulfur for gear oil.

These aromatics come from the same sources that aromatics found in lubricating oil come from - the ones in gasoline fractions just boil at a lower temperature.

Just think of it like this.

Sure, maybe. But it seems silly that a government wouldn't make it mandatory. Something that saves people money is generally pretty popular, as is protecting the environment.

Hey all...

We've got some Gas Economists coming onto one of our shows Wed. Night (I am a producer at a local TV station in Ontario)
Guess who is going to call in with the Acetone question, all loaded up with stuff... muuahhahahahaaaa...

~Xpc...

Hey, I'll see if I can wrangle the tape a get it online... hee hee...

There has been quite a lot of debate over this Acetone idea, but F*$K IT! I'll give it a try! In response to someone else's response to LT's statement:
Just think of it like this.

Would McDonalds put something in their food that would have you consume less of it?

If you know corporations, you know they would never do that.

I believe the oil companies have added other chemicals to keep your fuel/engine clean to keep you buying from them. YET they will not add too much as to keep you away. Sort of like McDonalds salads. You, the consumer, have decided to go on a diet, so MD's. would lose you if not for the salad. They would not however, go as far as adding a chemical to keep you from eating too much. Do I make :2cents:?

And if they did test this idea in the 70's, their cover-up probably was everything stated by rfilth. Remember, if you have money, You can cover anything up! Why the cover-up you ask? To stop the consumers from finding out that they are spending more money because the oil companies will not drop in a small additive into their gas for only a small amount, that will decrease oil sales, and save millions, if not billions of folks money.

I'm not sure if this will make sense to many, but if it does, please explain this to those who don't understand!

Well has anyone actually steped up to the plate????? I'd like to hear if it made a difference.

Still batting - Two balls, one strike

LOL! I'm gonna give in and try this tomorrow. I'm just way too curious. One day it'll bite me in the ass.

still on first tank! but the way its looking i'm going to get about 300mi+ (probably 310mi) on tank before the low fuel light comes on. btw its about a 16gal tank EDIT: went online to vehix, they say i have 19gal tank (anyone know for sure?) . It takes 14 - 14.5 gal when light comes on. that'll put me at around 20mpg on my s-10 p/u. before this acetone and my K&N intake i was getting 17.5mpg.

anybody notice a diff in performance?

i haven't had noticable difference. I've been taking it easy, so its hard to tell for sure. But i'm sure with that octane theres going to be a difference. hopefully LT has some input, he's been running this stuff for a little while now too.

Ok I gave in and tried it, I have been doing it for about 5 tank fulls now. I drive a lot for work so I knew I could get this done quick. I don't have exact numbers but I seem to be getting "LESS" mileage, especially the last tank full where I got about 230 miles to a full tank which is 50-100 less then usual. Also I have devloped a much different exhaust tone at low rpms cruising at about 35-50 mph. Any ideas on that???

Stop using it and see if everything returns to normal. If not, then it probably was not caused by the acetone. If everything returns to normal after the second tank without acetone, then you know what to blame. You might consider decreasing and/or increasing the acetone concentration and see if that has a positive effect.

The change in exhaust note may be due to a difference in EGT.

Thanks I will try that!

i also put in the acetone. i went through three tanks already. i reset the computer. i usually get aroudn 16 town, and 19.5 on highway. with the acetone im getting 17 town and 21 highway. just thought that i would throw my experience with acetone up in the air. bye the way, 1995 LS 4WD

Wow what a thread.

I have been researching this all week. It seems that the only individuals that have taken the time to properly test and write about this have stated only positive results.

The suggested 1oz for five tanks then 2oz and so on. I have already put the first oz in my tank. Fortunatly I dont drive as much for work as I used to so it will be next year some time before my results are definitive.

So far I have noticed the idle start to smooth out a bit. Also the exhaust is starting to smell different. That may be from cutting off my clogged cat though.

I was very glad to see this topic on this board as well as Brians input.

I do know that having been in the automotive industry since High school, they arent your friend. They arent interested in being your friend. Yes they want you to like them, but they arent trying to do what is best for you or anyone that is not largely invested directly with their bottom line.
That goes for the Government as well. Its common sense. It is not profitable for them (Big buisness, Government) to look out for anyone else.

Thanks for all the great input everyone, even those with opposing views, and Ill keep reading.

I spoke with an ASE certified GM master tech about this, and while he had never heard of the acetone theory, he indicated to me that the computer reset in not needed because the computer adjusts instantanously, not based on history or averages.

I was just wondering, how is everyone checking their gas mileages?

Since so many people have tried it, was wondering if everyone was using the same method to check mileage.

Are you all dividing the distance by the number by the number of gallons. Or, just going by how far you can go before the low fuel light comes on or what?

It would be neat if everyone could put their seperate results together into one big database and then see the results then.

One more thing, what's with all the exhaust sniffing? It just seems so funny, thinking about you guys just hanging out down by your tale pipes sniffing the fumes, then trying to judge what's going on. It's kind of like in my imagination I see you all with clipboards and a piece of paper with a check list on it, checking off things, and comparing notes. I know it's not true, and that you are probably just noticing the difference from just being outside around the vehicle, at least I hope the later is the truth.

I am using the trip odometer for distance and the gallons purchased. I am averaging over three tankfuls to account for variation on how much gas is filled. I realize the trip odometer is inaccurate, but it is good if you are looking for differences in distances.

ok, I'm back in here.

Economy is up and it is staying up above 16mpg which I have never EVER seen in this vehicles lifetime.

Just a small update from the ole' LT. ;)

LT, how many tanks now? i'm either on 2nd or 3rd (probably 2nd). mpg is up, still waiting for $$ to come in for free-flowing exhaust. same here, i'm using my trip odometer as a basis for calcuations.

I am on my 4th tank now and for this tank I used no acetone so I can cancel any acetone concentration increase I could have from the last three tanks.

Every 4 tanks you should use straight gas, no acetone.

But I am still over 16mpg and I am glad you guys have read the thread and have got informed about this. It does work, and work wonderfully.

3MPG increase in the city over a year is a lot of gas when you tally it up.

I don't see any reason to use straight gas every few tanks as long as you add the same amount of acetone per 10 gallons of gas each fill up. The acetone will not concentrate in the tank. It will distribute evenly within the gas and be used uniformly.

I just don't want the concentration to creep up as the tanks go through the engine over time.

I understand what you are saying, but we never have the perfect amount going in seeing that most of the time we never get the exact amount of gas in that we did before or several other factors.

Every 4 tanks I go with straight fuel just to clean the slate. This has been mentioned in other places as well just to make sure you don't overdose.

I know, it is not required, but I think it is also a good way to see if the economy will drop as well.

Oh, BTW guys, remember that this is not really as effective in colder times of the year. You will see close to no results in the cold.

It is the summer time when this additive shines through.

The error in concentration of the acetone will average out over time. Some times you will add too much acetone and sometimes you will not add enough. These random errors will negate each other and have no effect over time.

Also, I expect the effect of acetone in colder weather will be engine-dependent, just as the affect of the acetone in hot weather is engine-dependent. Not everyone sees an effect and not everyone who sees an effect will have it dissappear in winter. Everyone has to determine what happens in their truck independent of what others find.

Not everyone sees an effect and not everyone who sees an effect will have it dissappear in winter. Everyone has to determine what happens in their truck independent of what others find.

Very true.

But I am one of those guys that always adds a little too much. =(

I am not saying my method is gospel nor am I saying you are wrong. This in my mind just removes any postential overdose situations.

Again, it is up to the user but from what I have read, you won't really need it in the winter seeing the engine will be running cooler already.

This acetone that you guys are talking about, does it only work in Blazers? I have a Cavalier and was curious about this stuff.

Funny you ask, my other car is a Cavalier and it has acetone in it right now.

Where do could I find some of this acetone additive? Did you notice any gain on your cavy? I have an aftermarket muffler...nto sure if this is the problem causing my poor gas mileage though. I seem to get horrible gas mileage and I don't drive it around hauling ass everywhere...occasionaly i do. Stop and go driving I know hurts it as well. I get on average maybe 18 mpg.

bh04, i got mine at Lowes hardware store. get the real stuff, blue aluminum tin, just says Acetone
