Adding Acetone in gasoline

I am a escape owner who has not yet had the courage to try acetone. I have a friend who has a prius and is using acetone on a regular basis and has gotten an additional 4-8 miles per gallon on average. He uses 3 oz. per 10 gallons. I have been sitting back and watching for a down side to the acetone, all seems well so far. I dont know about a cleaner burn , but he did say something about surface tension of the gasoline being reduced, making for a more efficient delivery at the injectors. Im not a rocket scientist, so Im not sure what all that means, but it is hard to argue with the extra fuel economy. My friend is a brave soul, who has deeper pockets than I do . so I thought I'd let him see if there would be any long term affects to his drivetrain. good luck.

I used to own a 1961 Saab with a 2-cycle engine. You had to add a quart of oil to the gas tank before adding the gasoline, to get better mixing.

Similarly, I would presume one should add the 2-3 ounces of acetone into the gas-filler port _before_ adding the gasoline, to get better mixing...right?

As I have heard, "eureka...I think I found it"..its true.. I drive a 2005 civic hybrid. I was averaging 42 to 44 city and 45- 48 Hwy. I started adding Acetone at the rate of 3oz per full tank (roughly 12 gallons). My resluts are very impressive. i now record 47 to 49 city and a robust 51 to 59 hwy but must add not driving like I'm going to the finish line of the Daytona 500 in first place either. This has cured my doubts about the use of acetone and to Brother BIG OIL , we found a way to keep passing the pump a little longer.

Of course I'm sure someone out there in our environmentalist world will try to think of some way to outlaw this... give em time. Cant let the little guy get one up on ya. But it sure feels good commuting to work and having to fill up only once about every two weeks....

Try it out and post your results. Don't worry about long term effects. My father's best friend has been doing it to his 88' Maxima for 200,000miles. It currently is at over 400,000miles with no problems.
The fuel lines are fine and it has no problem passing emmisions.

So far on researching and reading online testimonies I have not found any negatives except for no improvement in MPG. Yes there's always chance of something going wrong by doing it and messing something up (actually you'll more likely to ruin you paint job by spilling some on the paint) You can bet no car manufacturer is going to recommend or approve it if something goes wrong with your car least of all cover it under warranty. However there is risk in everything, there a risk everytime you step in your car. Albeit a small risk I feel it about the same about as Acetone. I have tried for the last few tanks and there is some improvement yet unfortunatley I did not record any data on before starting it. So where I see the improvement is going up hill the MPG gauge is definetly higher than before.

Forget about these magic formulas for improving gas mileage. They are ALL a waste of time and money. And the last thing I would be doing is fooling around with unproven additives for the fuel system.

I wonder how much you will save if you cause damage to your fuel injection system. Personally, I would avoid unproven addictives unless you have deep pockets. If this was the answer to higher fuel mileage, why isn't it in the fuels already?

Rick: "Acetone binds strongly to water, so if you get water in your fuel tank this can be a big problem. Although acetone dissolves nicely in gasoline, acetone and water do not. The little acetone-water droplets can clog your fuel injectors and cause problems.

These days, most gasoline in the US contains 5% to 10% ethanol. Alcohol also tends to bind to acetone, and although this does not cause problems, it does reduce the ability of acetone to lower the surface tension. So it's not at all clear that adding acetone to a gasohol mix will improve your gas mileage by much."

Also, absolute ethanol will actually pull water (humidity) out of the air, adding water to your gasoline. Bottom line, acetone and alcohol don't mix, gasoline/motorfuel-wise.

i have an older car with a carburator i am thinking of trying the acetont thing but am leary about the effect on any carb seals and gaskets,has anyone tried this on an older car?

All you folks concerned about dmage, please do some research. Many folks have done experiment soaking various rubbers and plastics in gas with much higher concentrations of acetone- no problems. Also, I have read that acetone is the main component in many off the shelf additives.

The amount being proposed in tiny.

I believe that the bigger mpg increase will be realized with less efficient engines, esp those with carbs. I'm gonna try on lawnmowers first.

As to why isn't already in gas if it is so good? As with anything, follow the money.

I'd be more concerned about water getting in the fuel. Regardless what fuel you're burning water is going to screw things up. I'll bet service centers can't wait for gasohol.

I for one do not think adding Acetone is a good idea. Have any of those who tested Acetone on rubber and other materials test the acetone under pressure or heat? Also from doing countless tests on "so called octane boosters" I have found that many will leave deposits on the piston heads and spark plugs because of different combustion temperatures from that of your pump gasoline. Has anyone checked to make sure that if the Acetone is not dissolving fully in the gasoline that it may also be leaving ugly deposits? Also Acetone is fairly cheap but you still are buying something to add 1-2mpg (on average) to your car. In my opinion it is the same as someone driving 20 extra miles to save a few cents on gasoline. You might want to do the math (depending on your car) and figure if this is really worth the risk. Another note: If octane is really being raised by acetone “most” cars will automatically retard for higher or lower octane. If you drive a normal pump gas car the ecu will automatically rich or lean gas levels to its preferred levels depending on the rating of your car. One day someone will prove me completely wrong but internet testimony just won’t cut it for me.

It may be a big screw up to my car while I'm using 3 ounces for every 10 gallon of gasoline in it but, so far it is running much smother and has more pep than before adding the acetone, if you have ever used B-12 in your car as a carburator cleaner, if you read the ingredients you will find it contains acetone along with other cleaning agents so, I'll run her with acetone till she blows cause, she's running so much better with acetone than she was without. Thanks mr Lapont for letting me know about this and I take my hat off to you sir.

Here's my brain storm on a possible reason why Acetone is not added from the refinery. My degree is not in chemistry nor do I claim to be one. So if a chemist can prove me wrong then please do so and explain why. I'm always willing to listen and learn.

Given Acetones' affinity towards water and the fact that a pertoleum company can not control the type or age of the holding tank it goes into, adding Acetone to raise octane would impart unacceptable risks to the company. The problem here is that those old fuel tanks in the ground at your local gas station behave exactly like your vehicles' tank only on a larger scale. Over time, water can, in small amounts, build up and settle out to the bottom of the tank. Adding Acetone to the mix might spell disaster for the company once the new fuel came into contact with the trace water in those tanks. Can you imagine what would happen if the media found a pattern of damaged fuel systems due to excessive water in the fuel? Acetone may be easy for you to add to your fuel but it's too big of a risk for big oil. If you choose to add it to your tank, "more power to you." If not, hey what ever floats your boat.

To all you doubting Thomases, I refer you to the following link: http://www.lubedev.com/smartgas/additive.htm

This guy must be a scientist, and he has been doing this since just after WWII, which makes me wonder if he learned about it in the service and perhaps this has been covered up.

I have a 2000 Insight. I have been adding 3-5 oz. of acetone to each 10 gallons of gasoline. I have done it about 80% of the time I fill up for the past 14 months. No question about it, I have gotten a dramtic improvement on my gas mileage, on gas that is 91-93 octane-rated, with the 10% ethanol mix part of the year.

The 10% ethanol makes my car buck and knock. It hates it. With acetone, the bucking and knocking go away. This is saving my engine, my exhaust, my lifters, my cam shaft, etc. And according to this guy, who presents exhaustive data (lol), it is good for the environment. The only bad thing about acetone is that the oil and gas guys won't like it if it catches on (which makes me wonder if some of the naysayers here are reps for the oil/gasoline industries - don't laugh, this tactic is used at political sites and letters to the editor sites all the time). In every other consideration, it is good. Good for your engine. Good for you exhaust. Good for your mileage. Good for the environment. Good for my budget.

Don't be surpised if your cars bucks violently the first few days. This was the acetone cleaning out my system. After that, smooth sailing. I have gotten as high as 80 mpg on the highway. I have averaged, with the help of cautious driving, 73 mpg over a weeks-long period. Overall, my mpg improves by about 20%!!!!! I cannot wait to drive from Illinois to California in September to see what I can average on a long trip.

A tip: Acetone is difficult to pour. I use a stainless steel turkey baster with an injector tip to move the acetone from the can to my tank without spilling. Afterward, I rinse the baster and the pure rubber bulb immediately and let them dry. Acetone evaporates quickly. I do wonder if over time the acetone will break down the rubber bulb on the baster, but so far, so good.

By the way, that link has other great ideas about motor oil, plugs and filters. The guy is a fanatic who has spent decades researching this stuff. Check it out and benefit.

acetone works great, ive been using it for 5 months with great results, my norm mpg is 26-28 and with about 2oz per 10 gallons my mpg is 32-35, runs smoother and quieter. but the ethanol makes my car run crappy

what am i doing wrong ?added 4 oz to 18 gallons no ipmrovment at all for 1st 50 miles

It also appears that some people have trouble adding acetone to their tank, use a graduated (and oh my god) standard 60 ml plastic syringe, you will not get any spillage even my wife can use it. Yes you can even take it to servo in freezer bag and it won't spill.

And surprise the syringe is not disolved by the acetone. Acetone will only disolve certain rubbers and plastics.

Good Luck

It's obvious that you are a supporter of higher oil and gas prices. The NORMAL population of people in the U.S would be happy with higher fuel mileage

If acetone dramatically increased fuel economy, do you think for a moment that any major oil company would say, in some way or form, "hey, we now sell gas that gives you a dramatic increase in mileage from a fill-up and we haven't raised the price one bit. So enjoy buying less gas from us and decreasing our profits. Our shareholders - which the President and Vice President and numerous other immensely wealthy families - will have to get by on less earnings per share."

If acetone dramatically increased fuel economy, the major oil companies - or anyone they paid off - would report this as a myth, dangerous or an urban legend - or some combination thereof.

Remember, the major US car manufactuers in the 70s and 80s, via top scientists and engineers, told the US public that it was technologically IMPOSSIBLE to build a car engine that got over 100k miles. They also told us that it was technologically IMPOSSIBLE to build an alternative fuel vehicle that could be mass produced. They also told us that it was technologically IMPOSSIBLE to get significantly more gas mileage out of the combustion engine.

ALL of these IMPOSSIBILITIES have been ACCOMPLISHED by FOREIGN car manufacturers! The US car manufacturers are playing catch up - and selling off parts of their holdings to compensate for continued declining sales compared to foreign manufacturers, particularly Toyota.

THINK people. THINK.

I own a 2006 Hyundai sonata. The gas mileage is probably the only downside to this car. I heard about the acetone mixture and decided to make a few alterations that were described in the reccomendations. I went from standard oil to synthetic, changed the air filter, inflated the tires to 40 psi, and added 1 oz of acetone to for every 5 gallons of fuel. ( 15 gal tank ). I noticed a huge difference right away in increased mileage. Before the changes my car was averaging 23.1 miles per gallon at 65 miles per hour. After the changes the increase was awesome averaging 34.2 miles per gallon at 65 miles per hour. An increase of 11.1 mpg. I havent tested it at 60 or even 55 mph, but am looking at doing so. I will post results when complete.

I just bought a 2005 Honda Civic Hybrid, with about 27k miles.
I am averaging about 33 mpg if I'm lucky, and sometimes as low as 15 mpg.
I am not running AC, and it seems to run really nice/not rough at all.
Sometimes the auto stop doesn't kick in.
The battery recharges quickly, but sometimes gets down to 1 or 2 bars.
When the car ignition is on but the car is not started, my driver window is very sluggish to roll up,
and several times stopped dead.

This is my dream car, what can I expect?? It is still under warranty yet, until October.
One time I put Plus in it and it seemed to increase my mpg just a tad.
I consistently use regular gasoline in it.

Also, I get shocked a lot getting in and out of the car. There is a severed wire under the dash
(security? speakers??)
I really need to get this in to the dealer.
It was a leased car, and I paid just a few hundred over wholesale price from a dealer.

Now I'm wondering why.. I should be getting much, much better mileage!!

Any thoughts as to why I'm getting such poor mpg??
It does rain 8 months out of the year in Oregon, and maybe the moisture
is affecting the battery??

Thanks!

The reason they don't added at the refinery is because it would increase the cost of production and with the better milage reduce demand. Therefore, the oil companies have no interest in reducing their profits and increasing their cost to produce the product. They have been adding acetone to gasoline in Europe for a long time now because in Europe they don't have public unawerness like you have in the U.S. If the C.E.O.'s of the U.S. went to Germany and tried running a corporation like they do here, they would be thrown in jail. I have friends who are from Germany and that is why I know this not from reading some magazine article. Acetone added in 2-3 ounces per 10 gallons can not harm your engines intake, hoses, injectors, etc... On the contrary, it will keep them cleaner longer. Have you ever wondered why a high milage car has gunk build up? That is because the gasoline that is being used is not sufficiently mixed with a detergant. You pay less at low cost gas stations but that is because they don't use addatives in their fule and pass the savings on to you. When you need to have your injectors or intake taken apart to be cleaned you will then pay BIG BUCKS for repairs. When I was younger and my brother-in-law who is a mechanic gave me advise on hor to clean the valves on my pick up I listened to him. He said to let the valves, rocker arm, etc... sit over night in a solution of gasoline and then the next morning use a brush to clean the corners and edges. WOW! that gasoline ate away at everything and left them new. When I put the truck back together it ran like it was new and had noticably more power. So, imagine if gasoline going through your lines is that powerful than the parts installed from factory must be able to withstand 2-3 oz. of acetone per 10 gallons. Sure, their is some guy out there who thinks more is better and he will probably butn out his engine. I would suggest trying it on an older vehicle first to get comfortable with the idea or a ar that is not under waranty so if somethin happens you will not be to upset about an old $500 car that you bought to test acetone on and be able to get almost that much from a junkyard when you are done with it.

Which oil company do you work for?????????? Acetone will not harm any of the components of your engine including the elasterometric seals when used in small concentrations of 3 or less oz. per every 10 gallons of fuel. The reason that it's not in the fuel already is because the oil companies would lose profits. Why do you think that they are adding ethanol to our fuel now!!!!! So we have 10% less fuel mileage and they can sell us more fuel for rediculously outrageous prices. As far as unproven, I have been adding a mixture of acetone and a few other solvents to my fuel for 4 years now and have not had any problems directly related to the additive. Oh Yeah, did I mention that I'm getting 36.5 miles per gallon from a general motors 5.3L V8 in a 4x4 truck??? Sounds like it's been proven to me......

I think it may work, but i am not exactly sure about the frictional damage that has been caused to the engine combustion.

my van is 1997 astro van v6 before using acetone my mileage
is 15 mpg. i filled 10 oz. acetone (100%) along with lucas
fuel treatment 16 oz. (for internal safety of the engine) in 25 gallons gasoline full tank, after few miles of aggressive driving i notice
a lot of difference, the accelaration is smooth and forcefull (without
hesitation), i also observe the engine temperature 2 bar less (engine
a little bit cooler), after consuming half tank, i took the miles run
and fill up ( full tank), i divide the distance made by half full tank and it reads 22.5 mpg ( distance made = 230 miles/10.2 gallons < half tank
filled up to full tank). morover the exhaust smells fruity smell, not
unburn gasoline. i also monitor engine performance by obii scanner
monitor and all parameters are normal, i'm just surprise with the new mpg. ( my astro van is 13 years old with 198,000 mileage but still
strong and no problem. i also use restore engine treatment every
change oil with pure synthertic engine oil since i bought this
astro van. well no harm in trying acetone as old saying risk taker
are rewarded with astounding new mpg on old high mleage van.

I think in adding an acetone in gasoline, it can be good, but it might damage up your car parts like the Fuel Injectors and the like. If ever that happens, you need to really change it with some parts that Delphi and other branded name parts will provide. I'm sure things will be at ease if you try to really monitor it first.
