That reminds me of a skit from an old Three Stooges skit where moe and shemp are listening to the radio and a commercial comes on saying, "Does your car have indigestion? Does it burp in the morning? Try new Burpoline, the only gasoline containing bicarbonated soda!"

FYI - it's from "Sing a Song of Six Pants"

Note their compatibility with this material in particular: Buna-N (nitrile). Note that it has "excellent" compatibility with gasoline, but it will have a "severe effect" with acetone.

Why is this important? Because most seals and o-rings in fuel systems are made from Buna-N. A small leak in your fuel system could lead to a big car-b-que on the side of the road."
Whether it's true or not, it still sounds risky. I know acetone will literally melt/fuse plastic parts together. The amount might be a very low percentage but what about length of time acetone exposure to the car's plastic parts within the fuel system?

Here's link to a forum acetone/gas
More topics on acetone/gas ingoogle

The reaction that happens when acetone melts plastic generates a noticeable amount of heat too, which probably isn't something you want in the engine or gas tank of a car...

Well, if yer gonna do that, why not go ahead and put 0w-10 instead of 10w-30 oil in your car.

Why?

Lighter weight oil is more efficient in your engine...lower viscosity means less drag.

Of course, it will destroy your engine over time, but think how happy you'll be saving a few $$.

Let's summarize...

1. You're an idiot if you blindly believe the latest crap circulating on the Internet without any substantive evidence.

2. Additives, specifically Acetone will f*ck up your car.

3. All brands are the same; they all buy from the same refineries and high-octane gas is for suckers and fools who bought cars with high-compression engines that supposedly "require" the fuel, which they don't, but if you want to take off from the red light 0.00001 sec faster and impress the dork next to you and you have the car that can take advantage of the higher-octane fuel. Knock yourself out dork

PLEASE LOCK THIS THREAD OR LET IT DIE.

Another thing to remember: in older cars, you'll have all sorts of varnishes built up in the fuel system. Tank, lines, pump(s), the works. Seeing as we used acetone as a solvent in good ole college organic chemistry, I'm guessing all that crap will get dissolved, and your combustion chambers will be treated to a nice concentrated chemical soup. After the solvent is burned, the much higher carbon content residue might make for interesting deposits on your exaust valves and further downstream.

Aside from that, increasing volitility of your fuel can do all sorts of things, not all beneficial. In the good old days of flush toilets mounted on top of your engine (carburetors) this was much more of a factor than in modern fuel injected engines.

Fuel is complex. You want a big ole mix of various length hydrocarbons, which burn at different rates to provide an even flame front which pushes the piston evenly, instead of just generating a big slam at around top dead center. Think about pushing a cardboard box with your palm to move it, vs. just punching it.

Want better gas mileage? Get thinner, high profile tires to reduce rolling friction. Those 225/35s on your civic are murder on gas mileage, put the 165/75s back on!

Rip out the soundproofing material, remove extraneous things like back seats and all the garbage in your trunk. Get rid of the 1200 watt stereo -- the power to drive it ultimately comes from your engine. Replace heavy metal body components like hood, trunk and door with lighter weight plastic parts. Routine scheduled maintenance is important. Old sludgy lubricants don't do as well as new slimy lubricants.

Air + fuel in = power (force) out. Force = mass * acceleration. If you reduce the mass, or parasitic friction as a constant, you will reduce the need for the energy to accelerate that mass, all other things being equal. Which means you'll use less fuel.

the best way to do it is to excelerate a lot going downhill, just bearly on flat ground, and take your foot completely off the gas going uphill. hopefully you live in an area where there is terrain. dont be affraid to be going 55 one second, and 35 another.

My god where to start. First off I don't think using this blindly is a good idea, I would need more information before using it myself in my vehicles. Now for the fun part.

80% of you people are dense beyond belief. 20% are spot on, but are overwhelmed by the 80% retards.

Acetone is used as FINGER NAIL POLISH REMOVER, among other things.

Ever heard of Hollywood? If he used acetone it would have been more believable, but yes unconditioned rubber can be eaten away by gasoline. I believe rubber bands are unconditioned and would be eaten away by gasoline eventually, days perhaps?

What Super and Midlander suggested make the most sense. Keep your car tuned up, correct tire pressure, and alignment and you will get better fuel economy than if you didn't do these things. Acetone may give you 2 to 3 mpg more but it will hurt your fuel system slightly, in the long run you could end up paying for it.

LOL, you are funny. The seals will go long before it eats away at the plastic. If you check your facts, ACETONE... is sold in PLASTIC containers.

Welcome to the 80% club. Amber, you ever use finger nail polish? Ever take off that polish with ACETONE remover? How hot does that get, anywhere near the temperature of burning gasoline? Didn't think so.

ROFL I hope you are just adding fuel to the fire.

This thread is a big joke. You are the only person that cares about your car. If you care about your car, don't do this to it. If you think the REWARDS outweigh the RISKS then go for it.

How exactally do you EXCELERATE? Maybe I should update my Office XP or something

Well ive tried it, cant say if it helped or not. Havent really "tested" or have any method of testing mpg. Most of this thread is a bunch of bs anyway.

A little bit of Acetone wont do sh1t to the car. Im reading about ppl bitching that itll kill you! Itll eat away the plastic!! Dont do it, its the END!

Whats wrong with you people?!?!
Read up a bit more. Acetone isnt some radioactive substance thats going to mutate your cells.

Copied from someone who seems to know what there talking about from the other site thread,

#1. Acetone will wreck your fuel lines: This is partially true but false in this context. You are directed to use 100% pure acetone, which is a solvent, but one of the weaker solvents out there. Yes, it does dissolve plastics and rubber, but not at the concentration that you'd be adding to your tank. The article mentions adding 1 to 3 ounces of acetone per 10 gallons of gasoline. 10 gallons of gasoline is 1280 ounces, which is less than 1/4 of a percent. The solvent nature at that concentration would be negligible if at all.

#2. Acetone will kill your car: Acetone will NOT kill your car! Remember that Gasoline itself acts as a solvent. The only parts that acetone (concentrated mind you) would damage would be cheap rubber and plastics, neither of which are found in an automotive fuel system. If 100% pure acetone ate all plastics, why would it be shipped and stored in plastic containers? Acetone will not harm metal either. The only issue I can see would be with blow-by... Blow-by is the process in which the combustion blows past the rings. This happens in every engine to some extent, much more in older engines with worn rings. One might think that the Acetone (after quite a bit of time) might break down the oil, but if you change your oil often, this should be a non-issue. Using Synthetic such as Mobil 1 might reduce the risk all together.

3: Remember that acetone is not being added as a "power-add" such as NOS. The purpose of adding the acetone is to increase mileage by increasing the vaporization of the fuel. No fuel or engine completely vaporizes the fuel. The better the vaporization, the more efficient the engine will run. Acetone would increase vaporization because it supposedly reduces the surface tension of the fuel. The theory is such that a fuel having a reduced surface tension will vaporize easier due to reduced cohesion and adhesion. Cohesion is the strong intermolecular force that helps keep like molecules together. In addition, one could theorize that vaporization could be increase by reducing adhesion, which is the attractive force between two unlike molecules, like a molecule of fuel and molecules of the steel, iron or aluminum inside your engine. Simple physics; if you reduce the cohesion and adhesion, you reduce the fuels natural ability to keep itself together or sticking to parts in the engine, which are both counter-productive in the vaporization process.

"10% ethanol in my gas sucks, why should I use acetone"? Ethanol will NOT increase gas mileage! EVER! It takes about 1/3 more ethanol to create the same amount of power than gasoline. Ethanol is used for a few different reasons, one of which is to reduce emissions, another is to subsidize farmers. Ethanol DOES allow you to run MUCH higher compression ratios as it is much less prone to detonation, which is why you see funny cars running it. Running an engine on pure ethanol, you could theoretically increase the compression (run a turbo or supercharger) and get much more power out of a smaller engine. There are also issues with doing this, but that is another subject. Acetone is nothing like ethanol and the person who infers that is a complete moron.

There are many that feel that Propane is one of the most efficient fuels to run a combustion engine. One can assume that this might be true because propane is already almost completely vaporized, which wastes less fuel. If a product added to gasoline increase the vaporization, one could conclude that it might increase mileage.

I'm not saying you should do this, but investigate the facts before saying it's a bad idea, just as you should before actually doing something like this.

Please, do not be ignorant and try everything that you see. At the Saab 92x forums we already had a discussion over this. Take a look at the rest of the site and you will realize these people are a lot of loonies. Why do I say that? Read this:

Weather Modification

They are talking about regular people that modify the weather and how the federal government is going after them with psychic atacks, etc. Ha Ha Ha Ha! I am a Chemical Engineer and I will tell you one more time, do not try this! I can go point by point and show that most (not all) of his points are totally false, but I do not have the time. Also take a look at how much MPGs were gainned by the acetone! From 35 to 50 MPG or something similar? Please...

DO NOT TRY THIS, IT MAY CAUSE SEVER DAMAGE TO YOUR FUEL SYSTEM

If you still try then so be it. Darwin would be proud.

Hey, my home is P&N. I take everything with a grain of salt. I did get a lot of information from starting the thread though. Good work even to the couple of posters who think this is P&N. Thanks. I will hold off unless I can talk a friend into trying it for a month or so and see how he does. There is snake oil and then there is the little revolving magnetic display that they sell at the Hamfest that actually works. Sometimes you never really know until you try.

You should also realize that if I talk you into paying me $10 to wave a chicken bone over your car to improve the gas mileage it also "Works". The catch is your brain is connected to your right foot, so when you "think" you should be getting better gas mileage, it tells Mr Foot to take it easy, and bingo, better gas mileage.

So where can I get one of these "chicken bones"?

if you really want to improve your gas mileage, slow down. seriously. i drive a 2004 honda pilot. it's a big sumb!tch. but, i increased my gas mileage from ~20.5 to about 23 mpg.

the trick is, accelerate at a moderate pace, until you get into 4th (or whatever your overdrive is) gear. the STOP ACCELERATING! for me, that's about 65mph. when you roll over into high gear, you're going at the highest speed with the lowest RPMs. that's the sweet spot. you can even slow down a little, get the RPM lower, and still keep it in overdrive.

for example, at 65mph, i'm doing about 1600RPM. if i bump it up to 75mph, i'm doing about 2000RPM. is it really worth having the pistons fire 400 more times per minute to go 10mph faster? probably not.

another factor that plays a huge part is wind resistance. as your speed doubles, the wind resistance quadruples, so you need more and more energy just to overcome the wind resistance. and that energy comes out of your fuel effiency.

a better solution would be to reduce the numbers of drivers out there. stop producing v6 and v8 engine, those are stronger but a waste of gas.

In japan, v4 engine are numerous as gas are expensive compared to here. Americans need to learn from the japanese to solve their oil consumption problems. oil spill is disasterous, in the future we will all have to pay a price for this and that could mean the end of the world as we know it.

Streamlining traffic flow would help a lot nationally. Everybody wants the individual to fix the problem. How much gass mileage do you get at a red light?

Why yes, in fact the plastic GAS container I recently filled up at the as station got completely eaten away.

Oh wait, no it wasn't.
