 |

Saw this on another site-
http://pesn.com/2005/03/17/6900069_Acetone/
Anybody willing to try it and post the results?
HERE IS THE ARTICLE:
| Quote: | Acetone (CH3COCH3), also called dimethylketone or propanone, is a product that can be purchased inexpensively in most locations around the world, such as in the common hardware store. Added to the fuel tank in tiny amounts, acetone aids in the vaporization of the gasoline or diesel, increasing fuel efficiency, engine longevity, and performance -- as well as reducing hydrocarbon emissions.
How it Works
Complete vaporization of fuel is far from perfect in today's cars. A certain amount of fuel in most engines remains liquid in the hot chamber. In order to become a true gas and be fully combusted, fuel must undergo a phase change.
Surface tension presents an obstacle to vaporization. For instance the energy barrier from surface tension can sometimes force water to reach 300 degrees Fahrenheit before it vaporizes. Similarly with gasoline.
Acetone drastically reduces the surface tension. Most fuel molecules are sluggish with respect to their natural frequency. Acetone has an inherent molecular vibration that "stirs up" the fuel molecules, to break the surface tension. This results in a more complete vaporization with other factors remaining the same. More complete vaporization means less wasted fuel, hence the increased gas mileage from the increased thermal efficiency.
That excess fuel was formerly wasted past the rings or sent out the tailpipe but when mixed with acetone it gets burned.
Acetone allows gasoline to behave more like the ideal automotive fuel which is PROPANE. The degree of improved mileage depends on how much unburned fuel you are presently wasting. You might gain 15 to 35-percent better economy from the use of acetone. Sometimes even more.
How Much to Use
Add in tiny amounts from about one part per 5000 to one part per 500, depending on the vehicle -- just a few ounces per ten gallons of gas. This comes to between 0.075% and 0.350% acetone
Figure 1:
Percentage MILEAGE GAIN when a tiny amount of acetone is added to fuel. The curves A B C show the effect on three different cars using different gasolines. Some engines respond better than others to acetone. The D curve is for diesel fuel. Too much acetone will decrease mileage slightly due to adding too much octane to the fuel. Too much also upsets the mixture ratio because acetone (like alcohol) is a light molecule.
After you find the right amount for your car per ten gallons, and you are happy with your newfound mileage, you might want to try stopping the use of acetone for a couple of tanks. Watch the drop in mileage. It will amaze you. That reverse technique is one of the biggest eye openers concerning the use of acetone in fuel.
In a 10-gallon tank of gasoline, use two to three ounces of pure acetone to obtain excellent mileage improvements. In a ten-gallon tank of diesel fuel, use from 1 to 2 ounces of acetone. Performance goes too. Use about a teaspoon of acetone in the fuel tank of a lawnmower or snowblower.
Where to Get Acetone
The pure acetone label is the only additive suggested and is easily available from most stores in 16-ounce plastic bottles and in one-gallon containers from some large farm supply stores. But any acetone source is better than none. Containers labeled acetone from a hardware store are usually okay and pure enough to put in your fuel. We prefer cans or bottles that say 100-percent pure. The acetone in gallons or pints we get from Fleet Farm are labeled 100% pure. The bottles from Walgreen say 100% pure. Never use solvents such as paint thinners or unknown stuff in your gas. Toluene, benzene and xylene are okay if they are pure but may not raise mileage except when mixed with acetone.
Adding Acetone to Your Tank
When you fill up with fuel, note the number of gallons added, then calculate the right amount of acetone to add.
Some stores sell acetone in metal cans of various sizes, which are safe to keep indoors. However, it is difficult to pour from these cans, which have a flat top and short neck from which spillage is inevitable. In any case, while handling acetone, you should be wearing rubber gloves.
One option is to get a small graduated cylinder (available from science supplies store or some pharmacies). The small ones have larger intervals between markings so that it is easier to fill them to the level desired. The narrow cylinder can be held to the neck of the can to catch all drips. Then from the cylinder you can pour neatly into the tank. The small pouring spout suitable for laboratories prevents drips onto the paint.
Being etched with neat lines at each milliliter, these graduated cylinders are also good for measuring precise amounts -- in ounces or milliliters.
Additional Benefits
In addition to increased mileage acetone added to fuel boasts other benefits such as increased power, engine life, and performance. Less unburned fuel going past the rings keeps the rings and engine oil in far better condition.
A tiny bit of acetone in diesel fuel can stop the black smoke when the rack is all the way at full throttle. You will notice that the exhaust soot will be greatly reduced.
Acetone can reduce hydrocarbon emissions up to 60 percent. In some older cars, the HC readings with acetone went from say 440 PPM to 195, as just one example. Though mileage gains taper off with too much acetone, hydrocarbon emissions are nevertheless greatly reduced. Pure acetone is an extremely clean burning fuel that burns in air with a pretty blue, smokeless flame.
Acetone reduces the formation of water-ice crystals in below-zero weather which damage the fuel filter.
There are no known bad effects and every good reason to use acetone in your fuel. I have never seen a problem with acetone, and I have used ACETONE in gasoline and diesel fuel and in jet fuel (JP-4) for 50 years. I have rigorously tested fuels independently and am considered an authority on this important subject.
Cautions
Keep acetone away from painted surfaces, such as the paint on your car under the gas tank opening. Acetone is the key ingredient in paint remover. In addition to paint, fuels, including acetone, can also dissolve asphalt and most plastics.
Never allow skin contact with it. It can damage clothing as well. Don't breathe it. Keep children away from all dangerous chemicals. Read the directions on the container.
Acetone is a highly flammable liquid. Do not expose it near a flame or spark. Acetone should be stored outside, with proper ventilation, not inside your house. Gasoline and/or acetone will dissolve cheap plastics, so be sure the container you store it in will not deteriorate.
Solvents that can evaporate through plastics (which are, after all, derived from hydrocarbons) should not be stored in any such permeable materials. Keeping a plastic bottle inside the car, especially the SUV or wagon type without a trunk, could expose driver and passengers to small amounts of fumes evaporating through the plastic ? unless you always drive with windows open.
No Issues with the Engine
I have soaked carburetor parts in acetone for months and even years to see if there is any deterioration. Any parts made to run with gasoline will work with acetone just fine.
Contrast with Alcohol
In contrast, alcohol has been shown to be corrosive in an engine, yet they put THAT into gasoline. Alcohol in general is anti-mileage. Alcohol is no good in fuels. In Brazil, millions of engines and fuel systems were ruined by alcohol.
Furthermore, alcohol increases surface tension, producing the opposite effect from acetone. Alcohol in fuel attracts water. This hurts mileage because water acts like a fire extinguisher. Some cars may run badly and even quit due to the incombustible nature of the water-laden fuel. We know of a dozen cars that recently stopped running due to water in the alcohol and gas mixture.
In below-zero weather, the water and alcohol form abrasive, icy particles that can damage fuel pumps.
Hasn't Been Warmly Received
Questions asked of someone in the petroleum industry regarding ACETONE will often automatically trigger a string of negative reactions and perhaps false assertions. We may have heard them all. The mere mention of this additive represents such a threat to oil profits that you may get fabricated denials against the successful use of acetone in fuels.
The author has never found any valid reason for not using acetone in gasoline or diesel fuel. Plus it takes such a tiny amount to work. No wonder they fear this additive.
Political Action
You might Email this article to your government representative. After sufficient data has been collected, and that data supports the conclusions presented here, ACETONE should be ordered by Federal Law to be present in all fuels. While you're at it, request that vehicles be equipped with a MPG read-out to make it easier for consumers to know what is and is not working to improve their mileage.
If You Want to Do Independent Testing
For those of you who like to see the data yourself, there is a great little device available to check your exact gas mileage and more. See ScanGauge.com for an instrument that fits any car1996 or newer. It measures your real-time MPG, inlet temperature and many more details as you drive. This inexpensive tool should end a lot of debate over what works for mileage and what does not. We use the TRIP function to average the MPG at a steady 50 MPH both ways.
Since the fuel from every gas station is different from the next, the MPG performance will also vary. Then there exist a wide variety of additive choices at the terminals that affect quality. Also other variables in the cars performance such as warm external temperature versus cold external temperature, using the AC or not, headlights or not, incline of drive, etc. Try to eliminate as many of these variable as possible in your comparative testing.
Be consistent where you buy your gasoline because different gasolines vary tremendously. The best gas and the worst gas in your neighborhood will likely have a 30-percent spread in mileage. Same for diesel fuel. (In my experience with repeated test results, I have found that Texaco, Chevron and Canadian Shell deliver excellent gasoline mileage.) Try to keep down the number of variables wherever you gas up by using the same station, same pump, same grade or same octane before testing.
Incidentally, in almost all cases, the lowest octane is best for mileage. Most modern vehicles do not have high enough compression to justify using high octane fuels. 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. Listen carefully to your engine for tell-tale knocks or clicks when you start out from a light. The best mileage points to the correct octane when the engine is properly tuned.
The ScanGauge enables you to notice these difference and then see the difference with and without acetone added in various proportions.
Report Your Findings
PES Network Inc. has created an index page at PESWiki where you can report your findings. PESWiki is a publicly editable website where you can post a summary of your results, or create a full page, with all the details you wish to report, with images and links to video or spreadsheet data.
Other Additives Exist
There are of course other additives that improve mileage (which also have had less than a favorable reception by the petroleum industry). Certain octane improvers for example also aid mileage. We recently proved that Carb Medic from Gunk can raise mileage when 3 oz. are used with 2 oz. of acetone per 10 gallons of gasoline, even in cold weather.
Many products claiming to improve mileage are expensive and do not really help much. Others are fakes. For instance, a smooth flow of air into a carburetor or injector is far better for mileage than turbulent air. Yet many people deliberately introduce turbulent air into their engines. There are many silly myths floating around the car industry to fool the average person. Another is that cold intake air improves mileage. NO. Warm air improves mileage.
Test for yourself. Take a mileage check for each and every tank of gas or diesel fuel like we do. Your actual mileage is NOT that of a single tank full but the average of perhaps five tanks. To be accurate, you should not miss any checks. This takes discipline to get reliable results. Someday your car will do it for you with an MPG gauge on the dash. But for now, YOU ought to keep tabs on your mileage for all our sakes.

Follow-up
From: Louis LaPointe
March 19, 2005
Something that might be added:
In early 2004, a SmartGas reader named Dave in New York State filled three bottles with: pure acetone, half acetone/ half gasoline and straight gasoline. Into these he placed O-rings, pump diaphragms, plastic fittings, hose parts and other neoprene/n-buna stuff. He duped my experiments from back in the 50s. Months later he told me the pure acetone bottle was slightly darkened. Dave had carefully marked all the parts beforehand. He dried the parts to mike them again and noted after six months that the growth was about one-percent to two-percent in all the bottles, which was well within limits. Almost unnoticeable. He put the stuff back into the respective bottles where it may still be today. Dave has a background in physics and engineering.
He believes that everyone should do their own testing and not listen to the prejudiced opinions or words of others. There is way too much misinformation out there.
When I use acetone, I often add one of several other mileage additives into my 16 oz. Walgreen's plastic acetone bottle which stays in the trunk so as not to carry a large quantity container in case I get rear-ended. I am building a dyno facility to further test all the mileage additives and get perfect mixture figures to appear on the site this summer, I hope. Meanwhile the ScanGauge is being used daily by numerous persons across the U.S. running acetone and various carefully devised mixes and lubricants. Some oils can improve mileage substantially, notably Torco Oil.
Using the ScanGauge at 50MPH, my best mileage was 48-52 in my Neon a few weeks ago. Then I stopped the acetone to do some reverse testing. The next four tanks of the same Texaco gas showed 42-43, 37-38, 33-34, 30-31. No acetone when each tank was filled at half full. The drop was about 20 MPG overall.
The other person with me each time wrote down the results.
I am finishing a science article on the SmartGas.net site tonight--how to go about testing.
It concerns induction and the Scientific Method.

| Quote: | The same goes for Acetone (C3 H6 O), whose relatively meager supply of oxygen isn't even sufficient to support its own combustion, much less lend any to the gasoline reaction. Acetone does have one attractive property, however. It is extremely hydroscopic, meaning that it attracts and absorbs water. In the old days, the McCulloch racers knew this and used to mix acetone with their alcohol to help suspend the moisture that the alcohol attracted and put it in a more combustible form. It will do this in gasoline as well and, since water is not soluble in gasoline at all, but acetone, even acetone that has absorbed some water, is soluble in gasoline, it's a good way to deal with water-contaminated gasoline. But there's no power advantage to be had here and, if you're having a problem with water in your gasoline, you don't need a chemical to fix it. You need a better gasoline supplier. By the way, ketones like MEK and Acetone are also really hard on rubber and plastic parts, like carb diaphragms, etc. In concentrations of less than about 15 percent by volume, it is impossible to see any change in the combustion process, while anything over 10 percent may dissolve your metering diaphragm before the day is done. Sounds like a bad bargain.

I have used acetone in laboratory work for more than 30 years - but never in my engines.
I have personally seen acetone attack many plastics. I would not use acetone unless a Daimler Chrysler engineer assured me that all the fuel system parts were compatible.
Since 1994+ Rams have had a fairly high number of failures of the in-tank fuel pumps, {do search} and both Shell gasoline additives {do search}, and Marathon high sulfur gasolines {do search} have caused problems in Chrysler vehicle in-tank level sensors, that is even more reason not to experiment with acetone.
My gut tells me this is a bit of 'malware' spread over the internet by someone who wants to cause harm to other people's vehicles. |

I don't agree, 2-3 ounces for every 10 gallons (1280 oz) of gasoline is not going to hurt the fuel system or any plastics, that works out to 0.19 percent acetone. There is a company that sells relabeled acetone under the name XtraMPG, the guy that owns the company has told the press the only reason his business even survives is because most people will not go to the store and buy acetone and pour it in their fuel tank. He claims 30 percent mileage gains with his product. www.XtraMPG.com
This website has a fuel price article that mentions XtraMPG and the guy that sells it. http://www.bizwashington.com/wp-dyn/articles/A64180-2004May3_5.html
Roger Crawford, a businessman and independent researcher in Midland, Tex., takes a different approach to fuel economy. He has just begun marketing a gas additive he calls "XtraMPG." He says it boosts octane, burns cleaner and enables motorists to get better fuel economy and buy less expensive grades of gas -- saving 10 to 15 percent overall on gas.
What's in XtraMPG? "Most of us know it as nail polish remover," Crawford says. "It is simple acetone, a nonhazardous organic chemical . . . rated at 150 octane."
Crawford says he'd be happy if everyone bought acetone and added it to their gas tanks. But since people seem reluctant, he's packaging it as XtraMPG. |

yea, i don't know what to really think about this. i have messed with acetone many times and i can see how it would help with atomization of fuel. i can see how a person would need to be careful as well...
STLBluesRams34,
let us know the results of your own little experiment. i'm interested!

Just drove my truck home from a friends house, after sitting for a few hours I guess the acetone got mixed in well because my truck is running very smooth. Im not the kind of person that'll say something works well just because I like it. The engine and exhaust are quieter, noticabley.  I guess this stuff may actually work. The acceleration seems better, but Im trying to keep my foot out of it so that I can get an accurate mileage estimate. We'll see what happens mileage wise, it'll take some time. |

Let's keep this thread running guys, I can't wait for the results....I'm kind of tired of the arithmetic coming out to 14.7 MPG. I'd give anything to see 16 or 17 or 18.
Thanks,
Bill

Don't you think those 4.10s are killing you on the highway, I know it must be nice for racing around town, but on the highway you're getting killed. I wonder what the stock gears are in my stock 97 5.2 Ram, 3.56?

In all honesty, I think I would do better with 4.56. My truck probably weights 6000 pounds light. You have to remember it is a 2500 not a small 1500. If the 360 actually had some nut to get out of its own way, it would not be a problem.

You are a brave man and a pioneer.  If this works out well after a couple tanks, I say we send you a 6 pack for doing what we were too chicken$hit to do.

For an example of how a product can smooth out an engine's idle, but not affect MPG, take a look at this product:
http://www.le-inc.com/Literature/Product%20Flyers/2300%20Flyer.pdf
It has smoothed out the idle and 'feel' of every fuel injected engine I have used it in, but I have run several careful tests and have never found any better MPG. |
