I knew an old guy that used to swear by Acetone in the tank... he claimed the same benifits and said he started doing it back in the 70's during the gas crunch...
I never have tried it myself...
This should get interesting.

Acetone is a great degreaser also----so if you think you want to try it, you're gona need to go to the parts house and get a box of fuel filters, cause you're gona be changing them quite frequently!!!-----nobody remembers when the first no lead gas came out??----all the refinerys were adding airomatics, like benzene, tolulene, ect. to get the octane up and man did that stuff clean the crap out of the gas tanks!!!

I dont think this has anything to do with boosting the octane. Also it seems like such a small amount 1 oz.\10 Gal. that it wold not degrease anything. No one else has anything to say about this? I thought this would have sparked something.

It sounds too good to be true. the last 55 gallon drum of acetone I bought was only about $200. we use it to clean up with when doing fiberglass laminating. if I could simply add an ounce or two to ten gallons of gas and get more power and increased mileage, that would be SWEET! I remember when I was racing and a few guys were using propolene oxide to gain power. a small amount in the tank and it was like using nitrous. you had to richen the mixture drastically to keep from melting pistons. not very streetable. anybody here have first hand knowledge about using acetone?

I read what info was available on the internet about this, and will be trying it this weekend. We're towing out to BHC this weekend (260 miles each way) and normally get 11 mpg. I'll run 3 oz/10gal on the way out there and just gas back. The return trip shouldn't be much different as I'll have 11 gallons left from the first tank when I refill.

People don't think anything of putting a "fuel additive" in their tank, but look at the ingredients. Benzene, toluene, alcohol, etc. At 3 ozs per 10 gallons, it's not a big deal %-wise.

Okay ... I have a little bit of experience here. I have a degree in Mechanical Engineering and worked for Mercedes-Benz for 18 years with engine management systems (design/diagnosis/repair). So, I will give my 2 cents for what it's worth.
Lets take a look at what he is using as his sole test vehicle:
"Using the ScanGauge at 50MPH, my best mileage was 48-52 in my Neon a few weeks ago"
I got 40 mpg in my wife's C-Class on the way to Texas a couple of years ago ... w/ a larger engine than his Neon on pump gas, not a large claim in my opinion.
Lets look at what he is claiming increases the fuel mileage:
Acetone: a colorless, volatile, extremely flammable liquid ketone, with the formula CH3COCH3, widely used as an organic solvent.
This is where he lost me:
"The testing indicates best mileage is usually obtained with 85 or 87 octane gasoline. Too much octane causes a loss of power and economy. BUT too little octane causes the same things plus knocking."
Now lets look at Octane:
Octane: an isomeric paraffin hydrocarbons, with the formula C8H18, found in petroleum and used as a fuel and solvent.
So in summary:
Major oil companies as well as automotive manafacturers spend billions of dollars combined to purify their fuels and/or engine management systems to insure that they work properly in consumers vehicles without damaging parts.
If acetone was a better solvent/cleanser for fuels than octane ... I think that it would be mixed into the fuels from the oil manafacturers.
Everyone thinks that it is all about money & profits ... well it is. Oil companies do not want major law suits brought against them from automotive manafacturers/consumers for damaging internal engine components ... so they avoid mixing their fuels with chemicals that might potentially cause harm.
He also stated that it worked best with the lower pump octane ... well obviously :hammerhea ... a neon is not a very high compression engine that should run a maximum of 91 octane... he took out the solvent (octane) and then added a similar solvent (acetone) back into it resulting in running a premimum fuel again. With using the premimum fuel he started with a higher baseline and then added too much solvent, therefore breaking down the integrity of the fuel too much to burn properly.
I don't know ... but I figure that I will stick with what I feel comfortable with, running premimum fuel at the pump as it comes from the oil manafacturers. Then again, I am an Engineer so I probably tend to over-analyze everything.
I know that someone else will have somethinng to chime in on what I have said, but I just wanted to let all of those out there know that if their vehicles are under warranty and there is damage caused but additives to their fuel found by the manafacturers ... they might void the warranty, and that could be an expensive lesson. Be carefull.
Again, just my 2 cents ... I've already wasted too much time typing here.
Everyone have a good one,
BB

As I understand the theory, it is not acetone's octane or solvent properties that produce the claimed results. It is the chemical reaction between gasoline and acetone that lowers the surface tension of the gasoline vapor allowing better atomization. there are other test vehicles on other forums that have reported improvements of varying degrees, with the only common denominator of bad results being using too much acetone. With the small amount of acetone added to the fuel, I doubt there will be any ill effects. My truck is a 2001 Dodge 5.9l, so with the appetite it has for gas when towing, if there is any appreciable difference in mileage, I should notice on the trip out. From a technical perspective, an EFI engine is BEST case for this test.
Any changes to the air/fuel ratio that adding acetone creates will be compensated for by the ECU by injector pulse width and/or ignition timing.
If the government and the oil companies were looking out for the consumer, we would not have alcohol being added to fuel, or diesel costing the same as unleaded. It's just a big chess game, and you and I are the pawns.

Roostwear ,I totally agree with you on that last statement :coffeycup
My Dad worked for Coastal States Refinery for over 30yrs. at the Port of Corpus Christi,Tx...
I remember how during the 70's " Gas Crisis" he would come home and complain how the Major Oilproducers were just playing games to get the prices up....
After work he and buddies over a few beers would always mention how many TANKERS were out in the Gulf ...FULL of Oil waiting to get the OK from the Supreme Beings ( Government ) to dock and unload....but they had to wait ??? till it was in more Demand....BTW he also used to joke how much easier they had it at work because they were only at like 40% of operating capacity....hence the shortages :notam:

BUSBY

03-31-2005, 02:08 PM

I agree, we are all pawns in the big picture. And the addition of methyl tertiary-butyl ether (MBTE) ... has been a point of huge debates and there are major lawsuits and pressure for Legislation to ban the fuel additive.
I would love to see what the results are, however, I just wanted to let those out there know a little more about the subject & what I thought ... all while trying not to step on anyones toes.
I also agree that EFI systems are the best systems to test this out with becuase they will compensate with the air/fuel mixture to the appropriate needs of the engine.
The surface tension of the fuel will almost react exactly the same though with acetone as octane due to the chemical properties that are combined in the two.
Now, with that said ... there are subtle differences between the two (isomeric saturated hydrocarbons & extremely flammable liquid ketones), and that may be where the increase in mieage is.
Again, I just wanted to put my two cents in and hope it does work ... if I see that others have done it w/ no problems, I might be swayed in the other direction.
I would love to pull my loaded 45' hauler with my F350 powerstroke 6.0 while getting better mileage, it sucks paying $2.65/gallon for diesel!!!

Now I am real confused !!! I was under the imperesion for many years that OCTANE is the rating of burn time not an additive. Now some additives increase Octane. Now a thinner more Vaporous or Attomized fuel will help increase fuel milage !!! Isn't that what the Tornado claims, that it helps attomise the fuel better ???
Just my thoughts
Jim

roostwear

03-31-2005, 03:44 PM

The Tornado is supposed to create a "vortex" to increase atomization. :rolleyes: Here's more of the theory I've been chewing on. The "size" of a drop of gas is relative to it's surface tension. Since gasoline itself is not flammable (it's the vapor), the smaller the drop (atomization), the more surface area, and more vapor from the same volume. Supposedly another benefit of adding acetone is it's ability to suspend water and gasoline. If this is true, I would think the benefit to us boaters would be more pronounced.
Busby, don't worry about stepping on toes... this is theory at this point, and everyones input is welcome. I'm not an expert.... I'm a guinea pig!

Now you turned a whole new page to this thread ... this could go on for days :) , I love this kind of stuff ...
I am no chemist but Roostwear seems to be on the right track, if you split the sphere (drop) to atomize the fuel, you will also split and double the surface of the sphere (or drop) and therefore double the assistance in breaking down the surface tension ... the only question is is Acetone the best additive to assist the fuel? Now we're to the point of the start of this thread ... does it really work? Only one way to find out, right?

BUSBY

03-31-2005, 08:22 PM

I was under the imperesion for many years that OCTANE is the rating of burn time not an additive.
The octane rating of gasoline is a rating system telling you how much octane is inthe fuel. The amount of octane determines at what rate the fuel can be compressed before it will spontaneously ignite. The higher the octane rating, the higher resistance to spontaneously ignite from a false ingition source (carbon deposits, etc.). It is definately an additive ... with a rating system.
Now some additives increase Octane.
True ...
Now a thinner more Vaporous or Attomized fuel will help increase fuel milage !!!
I think that's it ... I wouldn't say you're too confused at all... just that the thinner more vaporous fuel has a lower surface tension while keeping the same volume of fuel. The question is ... will an EFI system try to compensate by increasing the pulse width to override or will the Acetone ignite with the same properties as the octane (isomeric paraffin hydrocarbons with the chemical formula of C8H18).
Basically, you stated in a much shorter version of what we are talking about, thanks.

There is a point of dimishing returns. Optimum is 2.5-3 ozs per 10 gals, although each application is different.

Went to Home Depot and bought a qt of 100% pure acetone for $5.97. I also bought a gallon (doesn't say 100% pure anywhere on it) for $12.97. I use it to prep parts for paint, so it's not like I won't use it if it doesn't work in the fuel. Tomorrow by about this time, I'll know if it works or not...........
PS- according to my calculations, with the $5.97 on the qt treating 107 gals, I need an improvement of .5 mpg to break even. :jawdrop:

Haven't left yet. I have noticed a couple things already that were mentioned in the articles/forums about acetone. Right after adding the acetone to a full tank (35 gallons, 10 ozs of acetone), the idle smoothed out noticeably, and the exhaust smell wasn't near as strong.
Should be hooked up and ready t roll around 10am......
PS- I checked my mileage when I filled up, and the 95 miles I traveled in my normal stop and go commute netted me 13 mpg (not towing).

Bottom line? Didn't do a thing for gas mileage, but did smooth out the idle, and make the exhaust smell better. :frown:

Also it's going in for a bullshit smog test this week and I'll compare it with the last test, I'll post the results!..
Art;
I failed smog without it, ran a tank of gas with acetone thru it, and then refilled with a full tank and I think 3 oz of Acetone and it passed.
Car was a 65 Belvedere with a 426 Big Block in it. Engine had a 750 cfm double pumper holly and headers on it, about 9.5 :1 compression, big valves and a pretty hot cam. The engine was fresh, but I figure the cam was too big, especially at idle and just off idle. But it was a 4 sp car, so it didn't matter.
It passed no problem with acetone in the tank.
Option 2 was to bring Joan's toyota down and use that to get thru smog testing!! :jawdrop:
I should try it in the Windstar, I run the damn thing about 1000 miles week!! :mad:

Does the acetone dry out valve guides, carb gaskets, etc ? I'm curious to try some in my next tank of the boat mixed with some marvel oil. 2 24 gal tanks, so I will need about 7 ounces per side .... ?
In the quantities you would add to your tanks, you won't see any effects from the acetone. Curious, why would you add Marvel to your fuel, and what benefit do think it has? Whatever "lubricating" properties it has, I would think would be outweighed by the detrimental effects it has on the fuel.

There used to be a product on the market called Mix-i-Go for gasoline engines, and a similar product called De-Zol for Diesel engines.
this was basicly a surfactant (same as soap) which broke the molicules of gasoline down for better atomization & burn.
My Dad & I both worked for a Mercedes Dealer and got quite a few customers using it. Out of a large number of "test" cars, all showed a marked improvement in fuel milage (10-15%) and much cleaner plugs & injectors.
This is still available, only under a different name now.

I am really not sure what actually happend but it is running way rich and the comp can't ajust far enough to compencate. I bet that the Acetone helped clean the fuel system.

A temp sensor gone bad would cause that.
I would agree with you but being they have 463K on the injectors, OEM '91 and the over all gas milage has gone bad too, 130 on a 20gal tank, 6.5mpg. Hell the boat is getting about 2.5mpg !!!!

Get a digital VOM and check the O2 output. That'll cause an overrich condition also. Highly unlikely your injectors are bad. If anything, they're probably flowing right for the first time in 300,000 miles!

9oz for 32-34 gallons. I should have been right on the money.

I'm trying 2oz/10 gal in this tank. It'll be mostly street/traffic driving, so we'll see if it works in a couple days.

Just did it for two weeks in the wife's truck, no mlieage increase but it sure cleaned out the fuel system and the motor runs so much better and idles smoother than ever also it passed smog cleaner than ever and that's with almost 400k on it!... Now I'm going to try it in my dually on the way to Needles and see what it does for it, let you know when I get back next week!..

'86 Buick Regal Limited, 3.8 electronic carb'd V-6, 5 oz/20gal
24.36 with acetone 22.16 without acetone
All highway driving, weather within 5 degrees of the same, Maybe it woirks better on carburated engines?? Much better idle, no foul fuel smell with acetone. Will be checking in town this week to verify the results. Could tell within 5 minutes after filling up that I didn't have acetone in the mix.

I filled up, and after 304.6 miles with 2oz/ 10 gals, my mileage......... unchanged. This was mixed driving.... street, highway.
Just for giggles, I think I'll run it in the boat at FC3.

I think tahiti350 and Mike have a good idea! That acetone will help break the fuel apart better leading to a better burn. The large engine w/ big ports need all the help they can get to pull the fuel apart.
On a fuel injected engine it takes x mount of fuel/x amount of air to run properly (mainly go rich/lean to make the cat converter do it job properly). As all are seeing, it does not seem to make a difference on mileage. But does make a smoother running engine cause the fuel is split easier. :cool:

I'm thinking that there may be some benefit to carburated engines. My test bed is a 5.9l mpi, and is fairly (?) efficient. A carburetor is less efficient and may respond to better atomization.
I'll find out in 2 weeks......
