Acetone

Has anyone added it to the tank as a way to increase MPG?

No reason it should. The heat of combustion of acetone -- the amount of energy you get when it burns --is about half that of gasoline.

That is just the latest false rumor-du-jour. Ignore anything that sounds too good to be true.

I dont think its about the combustion of the acetone but how it helps the fuel burn.

You seem like you believe it, so try it out and let us know if you gained any MPG.

Says who?

Sorry for not making sense, I started this thread to simply discuss it and get some real world feed back with people that have tried it on another website and Jerry locked it before it had time to get off the ground. 5 or 6 post maybe and Wham! Mod foot!

There are always some who believe in snake oil. There is enough evidence that points to damage to some non-metallic parts like some formulations of rubber like is used in o-rings, hoses, etc. that I wouldn't even consider using acetone. There's just too much risk and there are those who report their fuel pumps and fuel injectors were damaged from acetone.

Acetone is a powerful solvent and there are indeed some types of rubber it will damage. Do you know which vehicles have the types of rubber formulations in things like fuel injector o-rings, fuel pumps, etc. that are suceptible to damage from acetone? I didn't think so.

If you're willing to risk serious engine damage for some miniscule improvment in mpg which is debatable at best, be my guest. And I WOULD'T CARE even if you claimed to have run acetone for 900,000 miles without damage... I just don't care what is claimed by some about acetone, I'm not using it because the risks outweigh the claimed (by a few) slight improvement in mpg.

If you havent tried it, you dont know if it works. All you're doing is reading what someone else typed on the internet.
I have tried it, for the last 2.5 years, minus a tour in Afghan. Not in my newer 05 Wrangler but my ole 99 XJ.
It's been very interesting really, I would say about a 25% increase. Too much and it will pretty much stay the same in MPG. I think 4 ounces in 15 gallons is about right.
Harm o-rings? Soaked in 100% acetone maybe, 4 ounces diluted with 15 gallons of gasoline? Highly doubtful.

But I dont blame anyone for playing it safe I guess, although if everyone did that we would have missed out on alot of cool inventions and discoveries.

I just dont trust big oil and our government to keep us hooked on gas the way we are. There are alot of smart people in the world, I'm sure there are other avenues for fuel and fuel consumption. Acetone is one that I believe is WAY understudied.

I'm skeptical of anecdotal evidence. I'd like to see double blind testing in a controlled setting on various things that claim to improve MPG.

I agree, I dont know why big oil doesnt spend more of those billions they make on such research.

thats a good idea. jutgin, do a very scientific test to evaluate MPG. test about 10,000 miles over a year or more. Use varied concentrations of acetone:gasoline, and document everything scientifically. Also document the affects on the fuel system and let us know how the o-rings on the injectors, lines and fuel pump do with acetone. You'll obviously need to cut all those components apart to verify any damage, if the acetone doesn't ruin those components before the test is over. obviously you'll do the statistical analysis to determine the power and relevance of acetone+gasoline vs gasoline alone.

I understand, but this is the internet. Everything you read should have this disclaimer.

Well I wish I would have documented better. I have tested as much as you have mentioned. And I may very well remove injectors and pump one day to inspect! That actually has me pretty interested to see it now.

I was thinking more of test engine running various things under identical conditions each time. Just a basic test to see how much it uses per hour or whatever. Maybe Mythbusters

The big question is not IF it would work but WHY?

The only way an additive to fuel would increase fuel economy or hp would be because what you are adding has a higher caloric value or somehow ensures a more complete burn. Since fuel most likely burns to near completion, I think we can assume that the second point is not logical unless you are somehow creating fusion.

If you dilute the caloric value of the fuel, then you will need to burn more to get the same amount of work.

But, while doing this, what if you are chemically increasing the air to fuel ratio? If you did this in the correct ratio, you would be in reality substituting some fuel for something else which does not combust the same but also does not interfere with combustion either.

Look at it like this. Let's say you filled your tank with 10 gals of gas and went 200 miles until empty. Then added 7.5 gallons of gas and 2.5 gallons of alcohol and still went 200 miles? Is this possible? In the first case you made 20 mpg and in the second case, you made 26 mpg based solely on the gas. I could see this working if the car could not correct the tune, but the air fuel ratio would be more lean. Remember, if you want to increase fuel economy, running more lean, to a point is always an option.

Keep in mind that there is precedent for burning water with fuel and water can even be sprayed into the intake which has been used to advance spark and make more power. Check out Snow Performance for example.

Even if these tricks do work, there are other considerations such as engine damage, cost of the additive, and emissions issues.

I think we all want to believe in the fountain of youth and it is easy to believe in some sort of conspiracy by the oil companies, but the reality is, there is likely no free lunch.
