tell me what you guys think.

I haven't even followed the link, and I can tell you that it's a scam.

^^^^^^

What he said.

I do have some oceanfront property to sell you though in Nevada. ;)

lol, under normal circumstances, I would agree with you. But if you look at the other videos the guy on this website made, he doesnt look like he would just do this to promote a product. as a matter of fact, here.......

check out some of his other videos. He's one of those "beat the system guys."

That acetone will boost it upwards of 10mpg is the biggest load of bullcr@p I've ever heard.

The other stuff on the other hand, like keeping your tires inflated, taking out excess weight, keeping the filter clean and using lower friction oil are all good things. People would be very surprised to find their mileage increase if they just used good maintenance practices.

Adding acetone will not significantly increase gas mileage. You can put all types of petroleum based chemicals in there. Toluene, Xylene, alcohol, methanol. About the only thing it does is mess with the octane rating of the fuel. If the vehicle isn't tuned for a specific octane it is pointless. Do yourself a favor and try the maintenance recommendations but skip the acetone. It's pure BS.

Yea, mabee.

On a side note, check out some of the other videos on that web site. One guy found a way to light a match with a laser you use for powerpoint presentations. Its crazy. This guy (the one with the acetone video) found a way to make traffic light change for you when you are trying to cross the street. I dont know how true that is, but its an awesome concept.

This is not a new topic, the acetone acts as an octane booster, but it won't get you better milliage. It's like dumping ethanol into your tank.

Actually, it can...here's how: If you are running cheap gas, then your car's computer senses the detonation and retards the timing...lessening the power and causing the engine to have to work harder to move the vehicle. If you raise the octane and eliminate detonation, then it will run with full timing advance and make optimum power and run more efficiently.

I think probably the two most significant things you could do is maintain proper tire pressure and minimize curb weight. That's not rocket science. Far as the plugs n wires go, what if you have a NEW car? lol. It's not realistic to think you can DOUBLE your car's mileage. That's just dumb.

And as far as the acetone thing and stopping the engine goes....you have to consider added wear and tear on your starter...and the cost of pure acetone, etc. All this may make this effort totally futile. You may save a few bucks on the front end but then lose it on the back. DUMB. Urban legend at its finest.

Well A, its still working the same way as an octane booster, which doesn't improve milliage.
B. The GTO requires premium fuel, and putting in regular will lessen the performance, and milliage, but it won't advance the timming to take advantage of higher than 93 octane without a programmer, making the acetone useless to a GTO owner except in the following condition, A, you fill up with 89 or 87 octane, then buy the equivalent amount of acetone to to raise the octane back to 93 octane levels...which isn't cost effective.

So in short, its bubcus.

Mild hybrids work by stopping the engine at stops and running the accesories so that you don't notice the engine stopping, they use a highly effecient belt to start and stop the engine frequently, its used in some GM SUVs and such, but I doubt doing it in a stock GTO would save you more than a mile or two per gallon, and even then the increased wear on the starter isn't cost effective.

The best way to save gas, drive less agressivly, and on long trips find a suv or mac, and stay behind them the whole way, even at 100FT back using them to break the air will increase your milliage by 2-5MPG, and use your cruise control to stable slight throttle variances.

Just as a side note, what is the energy content of acetone vs. gasoline?

For example ethanol has a lower energy content per volume than that of gasoline. I just looked recently at the EPA's mileage estimates of gas powered vehicles vs. e85 vehicles of the same make and model and the e85 mileage is FAR worse than that of gas. Granted adding tiny amounts of acetone to your tank probably doesn't change the energy content that much, but it's also a factor that this "beat the system" guy does not discuss.

Save your money folks and use tried and true methods. But frankly we drive GTO's so why bother anyway, I didn't buy the car for mileage. :D

Just as a side note, what is the energy content of acetone vs. gasoline?

A quick search reveals that the HHV for gasoline is 47 MJ/kg, while the LHV of acetone is 28.548 MJ/kg...sorry I did not give you an apples to apples comparison. I am not feeling overly ambitious this evening. :o

This is true, and on NA applications E85 is almost useless as anything but a cheaper fuel, the advantage of E85 comes in its higher octane rating, at around 105 octane, this is an advantage on FI applications because they can increase the the amount of boost they can inject into the engine and thus increase horsepower to overcome some of the inefficiencies of the engine.

I remember hearing that the 2.0 Turbo saab engine jumped 30HP from running E85..thats a good 50-60 or so on larger engine...approximately.

Here's the BEST way to get better mileage from your car....


Always have your car hooked to the back of your buddy's car with a bar...half the time you push, half the time he pulls. When you're not pushing, shut your engine off. LMFAO!

nice one mechanic.....oh
run corn oil
LMFAO

I recall an episode on "Mythbusters" on fuel saving. They debunked the acetone in gasoline myth actually getting less MPG with it.
