got this in an email from a friend of mine...everything from stupid to silly...then the acetone users got in it big time...
.................................................................................................................................................

I am laughing my butt off reading some of the comments here. It’s now quite evident to me that the ‘establishment’ (ie. media controlled by Big oil and ‘Big Brother’) has most of you guys totally brainwashed. I want to give you some FACTS based on personal knowledge.

I work in Harris County Texas (Houston). Here EPA emissions testing is strict w/ special tests done to pass inspection annually. I have used a .28 oz/gal acetone to gasoline ratio in 3 vehicles for over a year now, and emmissions readings on these vehicles have dropped 50% on average. All vehicles have shown an average increase in MPG around 10%. All have shown noticeable increase in power. The smaller 4-cyls (Toyotas) show the most improvement, but the greatest improvement was on my 140K mile ‘96 Plymouth Voyager V6. I had a ‘Service Engine’ light coming on indicating ‘Cylinder Misfire’… and it stayed on for 6 months w/o me figuring out the problem. I started using the acetone additive and it went off after 2 tanks!

I work for a major petroleum and chemical engineering company with over 5,000 employees in Houston alone… 40,000 worldwide. After sharing my info in the Houston office, about a dozen ‘brave’ souls tried it. The results I got back I will note below following my 3 vehicles first. I drive a consistent pattern of highway and intown traffic equaling 700 miles per week. I buy gas at the same station/same pump/same time weekly for normalization of test data, now 1 year out:

‘85 Toyota Camry 4-cyl = 10%+ MPG, better performance
‘97 Toyota Camry 4-cyl = 9%+ MPG, MUCH better performance
‘96 Plym GR Voyager V6 = 12%+ MPG, Corrected ‘Engine Light’

‘94 Chev P/U V8 = 12% MPG, more power, better emissions test
‘92 Ford Explorer V6 = 5% MPG, passed after failing emissions
‘90 Nissan 280Z V6 = 10% MPG, gets 28MPG hiway @ 75MPH

‘97 Jeep Cherokee = Passed emissions test after flunking
‘01 Toyota Pathfinder = (Ditto above)… 2 tanks after
‘94 Lincoln Cont’l V8 = (Ditto above); 10%+ MPG

All have been saying roughly 10%+ mpg, but most notably the increased performance. If you aren’t getting the mpg, you should be checking the air filters: requires more air to gain new burn efficiency.

As for asking oil companies…they aren’t going to tell you this is good for many reasons.
First, they CANNOT add the additive like others because it is so high end distillate that it won’t remain in storage for very long (it dissipates quickly)… and if they can’t control adding it they don’t want you to gain on their profit loss.
Second, if everyone did this and gained 10% mpg, the immediate loss of 10% market share w/o ANY profit going to Big Oil is a marketing “No-No” to them.
Third, the corporate farmers pushing ethanol have too much in the pockets of congress to let you know that something this simple works. They want you to burn ethanol (from corn) that maintains the fuel ‘inefficiency’ and keeps not only Big Oil company profits high, but adds another group to the mix in the corporate farmers of ethanol.

Lastly, if anything were going to damage an internal engine component, 'ethanol' would...at a ratio of 1:10 in your gasoline. Most cars built after ‘94 have compensated w/ updated neoprene, N-Buna, and nylon components to handle the ethanol mixtures. Acetone at the ratio mixes we are talking about is 1:200… so miniscule that it is basically immeasurable as to harmful effects on an engine.

The overall economic impact now w/ gasoline at $3.00/gal of even a 5% increase in mpg = net savings of $0.25/gal if you are purchasing acetone at $12/gal using it at a .25oz/gal ratio. Relationly, the effect is 5 cents per gallon for every percent increase you gain… and if you gained -0- mpg, you would still get a cleaner engine, prolonged engine oil life (less blow-by gas from cylinder rings into oil), and save the life of your catalytic converter… as well as CLEAN UP THE ENVIRONMENT! (Hey, if you are burning more of the same fuel, less of it is escaping into the air… “DUH!”)

So, you skeptics keep dumping your garbage out there. Anyone with common sense and a will to be environmentally cleaner will at least test the theory. You can see a noticeable difference in performance at the very least, and know that you are emitting much less hydrocarbons into the air.

Some of the things you hear...

Acetone is dangerous! Not as much as gasoline...you want dangerous, check out "Ethanol". Beauty shops have had women put their fingers in acetone to rid themselves of their plastic nails for decades. Fingernail polish remover is mostly acetone. Most "Engine/Injector Cleaners" use a much, much higher percentage of acetone in their products.

Acetone melts plastics! So does gasoline and ethanol. The car manufacturers had a fit retrofitting the automoblie industry after "Ethanol" was put in service years ago. The ethanol melted everything from fittings to injectors. The parts in an engine are impervious to acetone if the engine can run ethanol...more so to the tiny percentage used in gasoline for mileage.

What I have noticed is that Wal-Mart is now having to inventory more acetone on their shelves…just ask the mgr of the paint department. More ‘Joe Public’ is learning the truth than you skeptics!

Tried it, 2000 Dodge Caravan, 3.0 engine….Put 4 oz. in while filling her up, and then hit the highway…247 kms each way to be exact…I put the cruise on at 105 kph, and drove off…Filled up when I returned and put no more acetone in, drove that tank out and then filled up again, no acetone, then set off for the same 247 km each way trip, same cruise, bla, bla, bla…The van normally get around 28 mpg on the highway, on the acetone tank, I got just over 32 mpg.. This vehicle has 100,000 kms on it and was only ever estimated to get 33 mpg when it was brand new….Ya I know, must be a fluke right, wrong, I’ve run the test several times now during different seasons and the same results. The best is when I set her up with the acetone in the tank and set her through the DriveClean emissions test. I zeroed out on almost everything, so low in fact that they ran it again later in the day after checking their own machine, and the second run was the same as the first…
If you honestly set up a test and there isn’t something seriously wrong with your vehicle you should get excellent results as well…..

I still have an 1986 GMC Jimmy 2.8L … 270,000 miles on a virgin engine. I started to have issues with fouling plugs about every 6 months. I was soon to trash the Jimmy. I started with a 2 OZ regiment for every 10 gallons of fuel. I figured it was a junk truck what could it hurt. After the last 2 years I have not needed a set a plugs and my milage went from 17 mpg up to 22 mpg. Now my OD has turned over 285,000 miles.

Now when I read the fooools like BOB/Mooseman, I am sure they live in a apartment/cell in some big city(jail) and never leave their computer. I on the other hand am a certified mechanic and have personaly seen how clean the components (spark plugs/injecter tips) are and have yet to seen 1 system failure of fuel line degradation are injecter component or O-ring failure. (NOTE: I do not know about the composit floats in old carberators but the brass ones come out clean and the fuel filters last longer from the lack of varnish build-up)

It simply works and does so immediatley. I am an automotive machinist and know fact from fiction when it comes to the internal working components of any combustion engine. I am using acetone currently in a 1991 Mercury Grand Marqui. I have used this since 1980 and used it in a Simco Hydraulic well drilling rig for 3 years. You'd better believe the oil companies dont want you to think for yourself.

Plexi50-July 12, 2006



BOUGHT AN EXPEDITION WHICH WOULD NOT GET ABOVE FOURTEEN MILES PER GALLON ANYWHERE ANYTIME, TRIED EVERYTHING IN AND OUT OF THE BOOK. GUESS WHAT , ADDING ACETONE BROUGHT ME UP TO TWENTY ONE MILES PER GALLON ON THE HIGHWAY AND SIXTEEN IN THE CITY, I DRIVE THE SAME. SO ALL YOU BUTT HORNS THAT THINK THIS DOESNT WORK, KEEP ON WASTING YOUR PRECIOUS MONEY FOR THE ARABS TO PROFIT, CAUSE MY FORD ROCKS DOWN THE ROAD AT TWENTY ONE, AND I WILL ALWAYS BURN ASS-E-TONE…

Comment by Todd — August 26, 2006



Re: #105-I started using acetone [~2oz/10 gals] in my ‘93 Ford Ranger 3.0 X-Cab 4x4 about 1200 miles ago and stop n’ go mileage has increased from hi 15’s to l7.9.

Warmer weather and my heightened awareness of the fact I’m trying to improve mileage may account for some of that, but it cannot account for the fact that it most definitely starts quicker and runs more smoothly, with idle RPM’s dropping from 800 down to 725-750 range.

I’m itching to take it on an extended highway cruise to see if I can beat the 24.6 I posted on a trip to Calif. from Montana August before last…I’ve noticed the same thing at WalMart, Victor-they ALWAYS had 4 gallons in stock, and now they’re empty for the past 3 weeks…

Comment by Dean — June 5, 2006





1994 Ford Bronco 4X4 with the 5.8 best ever 13 MPG on first tank with 3 OZ per 10 gallons I got 14.25 MPG I am going to continue and will be trying it in my gashog Motorhome soon.

Comment by Lino — June 18, 2006





I am going to try this because I have a sister that actually works for a big oil company in Houston Tx., and she told me that her boss was not able to let the public know about this because of the lost profits that they would incur if the general public was to become aware of this on a widespread basis. She also told me that a lot of the additives in the higher grades of fuel were made partly of acetone, just not at the ratio of 2-3 oz per every ten gallons,also the additives were not pure acetone and that it was just one of several ingredients, and the pure stuff would surely increase power along with mileage. {She is one of the vice presidents secretarys of BP oil in TX. So I am going to try it and see what happens.

Comment by BST — June 19, 2006





Unlike everyone speculating but not participating, I actually tested this in my ‘93 Honda Accord. Your UNEDUCATED OPINIONS are only wasting everyones time. For those interested in the FACTS —- My car without acetone got approx 270-300 miles on a 15 gal tank. WITH ACETONE that number increased to approx 450 miles on the same amount of gasoline. Anyone claiming this doesn’t work is either: A) an executive of the multi-billion dollar oil industry with hopes to keep their profits so obnoxiously high by issuing DISINFORMATION to sway your thinking to save money on their monopoly. OR B) an absolute imbecile. Feel free to mail me and I will give you any help or information you need with this.

Could definitely be workable...

Although a lot of these high 'n mighty types listed here are ignoring a plethora of real-world costs and complications. In the real world, petroleum companies can't just toss in a major and potentially corrosive/harmful additive. It has to go through miles of governmental red tape and experimentation to let it be a legal additive, not to mention a complete lack of laboratory testing to evaluate how modern electronics would interact with it, and the complications/cost of the storage and logistics it would imply.

AND nobody is thinking about how all of this cost would most certainly be passed on to the consumer and might not mean a net gain for a while, while there are actually many other technologies out there in the world that have even more positive effects.

Not saying it couldn't work, but there's a lot of people in the world who have very strong opinions on things that they haven't thought through very well.

Yeah... Personally I choose to wait until someone posts about how his engine got screwed by the stuff. I'd rather wait and be safe than fork up for a new engine. I don't have the money to be a guinea pig.

Gas many years ago had acetone added. It was very unstable and I heard it was hard on the tanks and was removed. Myself I wouldnt put anything in my engine that wasnt approved.

The one thing I notice on their thread is that the newest vehicle the acetone was tried in was an '01, and the vast majority of the vehicles are much older than that. So if you have a beater go for it, but I'm not about to gamble my warranty until I see some definitive results.

i was testing it before my clutch/tranny went out on me. i seen decent increase in power and an increase from about 360-380 miles pertake i normall get between 12 and 13 gallons per fill up the 2 tanks i got after i started testing i got 420 on 12.6 gallons then 443 on 12.9. take it for what you will.

i am going to test xylene next then a mixture of them both and see how it goes.

these results are on an 06 ZX3 ses with a 5sp and 11k miles on it and 80% highway driving and mixed AC useage on the same roads over and over again useing either wal mart or chervon gas

my next test will be on my fiencees 04 se Zetec sedan with the 4sp automatic and about 62k miles on it.

i have spoken to techs about this, most say its something they wouldnt notice, others just asked why i would do soemthing like that.

3oz/10gal eh? I might well have to try this. My SVT already manages better than average mileage, if I could hit 35mpg regularly I wouldnt complain.

I've heard this discussed in the past, when I was a member on the Neon boards. The pattern is the same, the drawbacks appear to be academic more than by anybody's actual negative experience. We shall see...

so wait, acetone (which i have a jug of since i've been working with some paint stuff and all that) can increase my power and mpg? to this i say WTF sirs, WTF!

LMAO.

so do i just dump 3oz's in the tank when i fill up or what? i mean this is madness. it just doesn't seem right!

how in the world does it work? what might it mess up? (we have plastic tanks) is it worth a try? does it work the first time you put it in the tank or what?

And here's another question, as most of the responders have older cars. How will the OBDII electronics respond to this change?

I just have a natural distrust of people who end their arguments with crap like, "And if you disagree with me that just means that you are a Neo-Nazi child rapist..." (not a quote, but you get my drift)

The guy who emailed me this uses acetone (2 ounces per 10 gallons) in his wifes 2003 SPI Focus (5-speed) sedan. They bought it with just over 40,000 miles and now have almost 80,000 miles on it. They have used acetone in it since about 50,000 miles. He said she gets around 41 mpg on the mostly highway/ some inner-city driving round trip to work and back. She puts 120 miles a day on it 5/6 days a week. Only problem they have ever had was a vacuum leak this past week.

I found some more stuff about this acetone here. Makes for interesting reading if nothing else. Here is just one site I've found...

I've been using it regularly as well as mixing xylene basically like this 3 oz acetone, 6 oz xylene, 3 oz synthetic 2 cycle oil added to a full tank.

Just to be sure I went a couple of tanks without it on 87 octane and managed 28 mpg in my mixed driving. With the mix I was getting 34 mpg. I've been using it for 10k miles, no issues. The only bummer is that it's a pain in the butt to have to go mix in a glass container then use a funnel and rag for drips to get it in the car. It's not possible to use it on long trips, but you can use small plastic acetone bottles of nail polish remover. I marked the side of one to be sure I was adding the proper amount. If you add too much- the effect is the opposite. I've done it with and without xylene and 2 cycle oil, and truthfully I'd say there is not a noticable difference if you don't add the other two ingredients. Lucas Upper Cylinder lube seems to work for a lot of people, so I'm considering adding that along with acetone to see what the effect will be.

The only effect I can say that I've noticed besides more mileage and some power is that the plugs are totally clean when I check them- nothing at all, and the exhaust is a little louder. With dyno tuning it might be possible to get another couple of mpg out of the mix.

2 cycle oil never heard of that one in my research i will have to try that, but you need that much more xylene then acetone. thanks for the info when i get my car back i will have to try your mixture. my goal is 40 mpg

I work with a crapload of acetone. It makes rubber and plastic brittle. Thats one way it could screw your engine. How many rubber and plastic parts are in your fuel system? Quite a few o rings, injectors, carb components, etc. are susceptible to damage from Acetone.

I have read a few articles and studies about using Acetone. I believe this article to be the most informative.
http://peswiki.com/index.php/Directory:Acetone_as_a_Fuel_Additive
I believe it should work, but in the proper ratio. Be careful, read up on it. One time CAN hurt.

yeah...the guy that emailed this to me to begin with also watched that "Mythbusters" episode...

next time that episode's on...check the ratio of acetone to gasoline that they put in the car (way too much-remember only 2-3 oz per 10 gallons-more will give less mileage), car was definately not a tuned regular driven car (where they got it) etc...etc...

Anyone can make anything look bad, they just get there own experts (people do it all the time). But in everything I have personally found or the people that I have personally talked to...no one has had one single problem attributed to acetone use...(even when they put 10-20 times the amount that they are supposed to use to screw things up)

I'm leary of stuff like this too, but it has been around for over half a century...plenty of tests from jet engines to diesels. Check out the tests from any place that is not big business, gas/oil companies, government, etc...I know I was surprised at how many people use it in my area...they won't tell you unless you ask. From a couple of diesel truck owners (more power, way less smoke, better mileage) to a Harley motorcycle owner ($22,000 bike) and a few regular car owners (2003-2007-2 cars on warranty).

"Check out the tests from any place that is not big business,"

Show me a test that is done in a precise, measure, scientific way, such as the mythbusters dyno test. Every one I've seen has not been done under controlled, measured conditions and is anecdotal.

As I said, show me one controlled dyno test on Acetone by anyone. Just one.

penguin, who cares about controlled test on a dyno, the real world isnt controlled, why would we come on here and lie to people about this, i have nothing to gain from you or anyone else belieing me and i lose nothing if you dont. i am simply trying to help out my fellow car guy the more money you save on gas the more money for mods :)

pantherdan: if the motor can handle gas and ethnole and the other junk people put in there gas tank acetone should be just fine. i know i put some BG 44k in a cup one time and it did the same thing to is as the acetone did. and the BG is what dealers use to clean out the fuel systems

"who cares about controlled test on a dyno"

People who want to know the Facts and Truth. Why do you think the best tuners use dynos, instead of "the Real World" to measure the effect of their actions?

"why would we come on here and lie to people about this"

Why would people spread urban legends? Why would people say their toronado vortex generator gave them greatly improved mileage? Why would people spread messages saying to write your Senator because Congress is about to pass a law taxing the internet? Because they think they are helping others, no?

I'm sure you believe what you are saying, but that doesn't make it true. I am a mechanical engineer by training, including some study of combustion theory, and long ago found out that careful measurements under controlled conditions are the ONLY way to quantify the the effect of things in the "real world."

Ever hear of the "placebo effect?"

You must remove this effect from ANY legitimate analysis. And this can only be done via quantifiable measurement under controlled conditions, or statistically via an extensive double-blind real world study.
