Acetone In Fuel Said to Increase Mileage<O></O>

Readily-available chemical added to gas tank in small proportion improves the fuel's ability to vaporize completely by reducing the surface tension that inhibits vaporization of some fuel droplets.

Acetone (CH<SUB>3</SUB>COCH<SUB>3</SUB>) is a product that can be purchased inexpensively in most locations around the world, such as in the common hardware, auto parts, or drug 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.

It is used in the production of lubricating oils, chloroform, pharmaceuticals, pesticides, paints, varnishes and lacquers. If present in water, it is more likely to volatilize or biodegrade before bioaccumulating or adsorbing to sediments. Acetone will also readily volatilize and biodegrade in soil. It is also a common laboratory contaminant, so its presence in a sample does not always indicate its presence in the environment. Synonyms - Dimethylketone and 2-propanone.

Complete vaporization of fuel is far from perfect in today's cars and trucks. A certain amount of residual fuel in most engines remains liquid in the hot chamber. In order to be fully combusted, the fuel must be fully vaporized.
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, though the engine still thinks it is running straight gas.
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 3000, depending on the vehicle -- just a few ounces per ten gallons of gas. This comes to between 0.0003 % to 0.0025 % acetone maximum or approximately 1/15th of one-percent. Note that is around .78 cc per liter or one ounce per 10 gallons. Not more than three oz. per 10 gallons.


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 decreases mileage slightly due to adding too much octane to the fuel. Too much additive would upset the mixture ratio because acetone (like alcohol) is a light molecule and tends to lean the mixture.

After you first find the best gasoline in your area, then try the acetone amount for your car per ten gallons, and if 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 one 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 up too. Use about a half-teaspoon of acetone in the fuel tank of a 4-cycle lawnmower or snowblower. Or you can apply it with an eyedropper.
Where to Get Acetone
The pure acetone label is the only additive suggested and is easily available from most drug stores in 16-ounce plastic bottles and in one-gallon containers from some large fleet farm supply stores. But any acetone source is better than none. Containers labeled acetonefrom 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 have been okay if they are pure but may not raise mileage except when mixed with acetone. However the aromatics also raise octane.
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. Less is more. Remember all gasoline is different. Some will work better than others in the presence of acetone which is strictly a vaporization tool, rather than a fuel additive that alters combustion. The car computer still thinks it is running straight gasoline. None of your settings are altered. None of your engine parts are affected. Check out ScanGauge for an inexpensive MPG device.
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 and your truck or car runs smoother.
Acetone can reduce hydrocarbon emissions up to 60 percent. In some older cars, the HC readings with acetone in a 1986 GMC went from 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 can damage the fuel filter. Change that fuel filter every year to protect injectors.
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 (with burns all over me) and am considered an authority on this important subject.

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, gasoline alone can also dissolve asphalt and most plastics.
Never allow skin contact with it. It may 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, as is gasoline. 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. Read all the precautio

 

Hi,

How about this low tech blower arrangement?

http://www.hotrod.com/techarticles/engine/hrdp_1105_leaf_blower_supercharger/index.html


Rick

 

Don't know any other home remedy than to keep it tunned to the max.

I did figure something out a few years back that most of you won't believe unless you think about it real hard. All my vehicles get better mileage with the throttle pinned to the floor than they do at idle.

Just think about it before you say that is the stupidist thng I ever heard and make a fool out of yourself.

 

i'm pretty sure the acetone thing is an old wives tale.

 

If your geared down and moving and the engine is running less than 2k RPM you could get slightly better milage as the wide open butterflys would reduce pumping losses in the engine vs being barely cracked open.

 

Believe it or not, depending on your engine...properly ported or modern aluminum heads (with an increase in compression ratio..!) will increase milage...IF you can keep your foot from being down too far on the gas pedal..

With air/fuel flowing cleanly in and burn't stuff flowing properly out along with cleaned up combustion chambers, will work much better than unported ports. I've proved it time and time again to people over the years.

Mike

P.S. -Gearing down normally doesn't work if you go down more than one or two ratio numbers...it's a "combination" thing. If the engine wasn't designed (cam shaft) to run at 2000rpm, both milage AND power will be crap.

 

Ideling at a stop = 0mpg
WOT even at 6 gallons to the mile is better.

 

Damn and I thought no one on here could think.

We got a winner folks.

The acetone thing is not a mileage maker by the way it is considered to be poor man's octain boost and a lot of fellas swear by it.

If you are running an 8:1 compression wheezer you can boost the mileage just by boosting the compression.

 

Actually at idle, a vehicle may be moving 3-4 MPH. There's an old guy in our neighborhood who drives to the donut place that way every morning. If you get behind him, you'll know who I mean. The cops would get him, but they're already at the donut place.

 

Oh....that hurts.......

The acetone is a hoax. So are extended Throttle bodies....magnets on the fuel line....super low restriction air filters.

Cheap tricks for better MPG?

1. Proper air pressure in your tires.
2. Take all the un needed junk out of your car. Every extra pound is just more weight your engine has to get moving.
3. Keep the car clean. It doesn't help MPG, but you feel better about it.
4. When your a 1/4 mile from a light and you see the light turn red....take your foot off the gas. Saves a little and helps your brakes last longer.
5. Don't ride the brake....this has more impacts than you think....besides a drag on the engine....on modern cars with lock up converters, it causes the converter to unlock...this hurts gas mileage and causes the tranny to run hotter. How many of you have seen cars going down the fwy with the brake lights going on and off. Learn to drive with just your right foot.
6. Make sure you have the right temp t-stat in your engine. A cooler t-stat will NOT solve an over heating problem. Colder t-stats cause the engine to get poorer MPG.
7. Don't fill up when the tank gets half full. Wait until your down to a 1/4 or less....gas weights about 7lbs/gal. I know some people who never let the gas go below half because the 'think' it's bad for the engine...claim in increases the chance of sucking up dirt. That is what filters are for.

 

My first boss wrote a column for an Automotive trade magazine for awhile. One column was basically about all these items, filters, magnets, intake turbines, etc, etc, etc.... That claimed to increase mileage a certain percentage.

By his math if you added the 20% this doo-dad gave you and the 25% here, another 10 or 15% somewhere else, eventually your car, with enough of these things, will start producing it's own fuel! Amazing right!?!?!? It was hilarious to read, I wish I could find a copy.

Bottom line, if something is out there to get you better mileage its going to be strapped on most new cars. Example, Hybrid vehicles and electric cars.

Put a wedge under the gas pedal...My buddys got a Smart car, 50+mpg. I gots a 1964 Riviera ,3998 lbs of pure steel powered by a 425 Nailhead with 465 ft lbs of torque,12 mpg.I would get a limp dick if I drove a Smart car. I`m not rich,but if I can`t afford to fuel my hobby,I`m taking up golf, I hear thats pretty cheap.

 

I'll bet a car with a 1200cc engine gets better mileage than a 1200cc motorcycle.
The fun-per-mile will be higher with the bike, however.

 

Rebuilt 1st generation Dodge Neon for my college aged children the manual gets almost 40 mpg highway and the auto goes mid 30s.
A turbo adds power and efficiency if you keep your foot out of the turbo.
Have an old IDI turbo diesel F350 4x4 that is very efficient for a big truck.
Make sure your vehicles are maintained bearing, alignment, suspension, brakes.Always amazing how much some people with spend on fluff and ignore simple maintenance like rear end or transfer case lube or suspension and alignment.

 

A local bus company did a long term mileage test for a product similar to acetone. They found the savings in fuel to not quite equal the cost of the product.

 

Learning how to properly use your right foot on the gas pedal is the best home remedy for getting better gas mileage.

Use a vacuum gauge mounted inside your car and hooked directly to the intake manifold. Any movement of the throttle will show on the gauge. While watching the gauge you will learn to feather the throttle on take off and ease off on the throttle at speed. Maintaining the highest vacuum reading at all times will save on gas.

This vacuum gauge trick was used to teach drivers competing in the old Mobil Economy Run days. It works by teaching you how to be easier on the throttle. One hour of driving while paying attention to a vacuum gauge will be a lesson that will remain with you forever when you are trying to get better gas mileage.

Try it, it will work!

 

hi, some italian scientists recently developed a 14kw gen based on the origional pons and fleishman cold fusion. it would work like throwing a light switch. 400w to keep it going.14kw out.refuel by adding metal approx every 6 months as the reaction apperantly eats it over time . it would be interesting to see if you could pair it with a chevy volt. any thoughts? just my 2 cents.

 

Well I guess that it wouldn't use any gas and it would be a hit with anyone who wanted to build a dirty bomb.

Here is a tought a little off topic but no more off topic that an electric car I guess.

I had an old Chebby truck that I was getting 20-22 MPG on the highway. This is a fact witnessed by several HAMBers. It had an engine that I built from pieces and I had less than 2K in the entire truck.

Now lets go the full 2K for total investment to make it easy. A new hybrid runs somewhere in the neighborhood of 30K give or take a little and gets somewhere in the neighborhood of 32 MPG. At least that's what I have seen advertised. How many years will it take @ say 10,000 miles per year to reach the break even point on the new hybrid. You can use a gas price of 4 dollars a gallon if you like.

 

10000 miles/20mpg= $500 a year
10000 miles/32mpg= $312.50 a year

30k-2k=28k for car

28k/187.50=149.33 years

 

Detuning an engine and making less power is not synonymous with better milage. Milage is better equated to overall efficiency.

In August, I'm probably going to do a series of Tech threads about a daily driver build using my 63 Fairlane and a 289 combo built for mild performance and fuel milage. It'll be an experiment, but my goal is 23 mpg highway or better on 87 octane. Shouldn't be hard to get that mark, but hopefully I can surpass it.

 

Yeah ,but your pickup might not be happy parked at the Country Club on greenpeace weekend.

 

Home made remedies for poor mileage are not new. Gas was probably 20 cents a gallon when these were made. Any of the new gadgets probably are just as effective. ZERO The 100 MPG carb is a myth. I also have a "mileage maker" chrome add on fuel filter. Like an external fuel filter is going to make your car more efficient.

check your tire pressure and unload the trunk. Everything else is just pure unadulterated bullshit. I hate bullshit!

 

If one googles 'acetone in gasoline' lots of testimonials come up - pro and con. For the small investment of experimentation; it may be worth a try.
Googling octane boosters, there is another home brew of mixing toluene, mineral spirits and tranmission fluid (100:25:3, all in oz's). Use 16 oz's of this cocktail per 20 gallons of gasoline. The wonders of the internet

 

The tornado haha

Determining where your cars engine's sweet spot rpm is on the torque curve and staying there during your driving will yeild the best mileage. Over drive Trans doesn't help if it takes you off or below the sweet spot.

Different components and massage can alter the engines sweet spot, rear gear choice determines speed at that rpm. All you gotta do is keep it there.

My OT truck is a heck of a lot more lively to drive on E85 but the mileage goes way down. Fuel Cost per 1000 miles is about the same for 87 unleaded or E85 but its got more power for sure.

As a younger man, my friends dad owned a hobby store,we used to throw a quart of 40% glow fuel in with a tank full of gas, that was kinda fun.

If the engine has high, miles, not what it used to be, a bit uneven on compression, "Restore" additive works really well. Done a few blind tests and get the same comments, lots more power better mileage, smoother running. Before and after compression checks showed a pretty good increase.les oil consumption, less blow by.

 

So, I bought this ignition system that promised a 30% increase in mileage. I bought this new induction system that promised a 65% increase in mileage and HP. Then I bought these radial tires that promised a 15% increase in mileage. On the weekend I put it all on my car and the freakin gas tank overflowed!!!

 

It's a toss up. They act real proud of a car getting over 30mpg these days. Well if you could actually find a 1.2 in a car these days... You can get north of 30 on a liter+ bike easily, it's pretty much only the pure sport bikes that don't. Hell Hayabusa's get 44-47mph on the highway, and closer to 36-38 in the city as long as you don't ride like a lunatic. My Guzzi averages in the low 40's on a tank.

 

Funny shit right there.

On rare occasions if you use the Correct fuel sender for the tank and the correct gauge for the dash, sometimes the gauge goes up instead of down as you drive it.
Ask me how I know.

Here's my take on this: While I do watch my driving, tire pressures, loads, etc.... I also realize that hot rods are for fun, not stressin'. I drive mine everywhere (well my wife does) and when it needs gas, we buy more.
