Double your gas mileage.

[mfkr]

Don't know how much this would actually work. However, I do know that I was able to beat my emissions test with a 77 Buick Regal by adding a small bit of acetone.

Acetone easily hydrolyzes to to a di-ol with a very high vapour pressure. This in turn gives better fuel atomization, hence better fuel economy.

Is it safe C-Dal?

It's BS, don't buy into it. Your experience was coincidental at best.

Acetone is very bad to any plastic it comes in contact with. It will significantly soften rubber hoses for example. So extended use is bad.
Acetone does not improve fuel mileage, mythbusters (http://en.wikipedia.org/wiki/MythBusters_%28season_3%29#The_Great_Gas_Conspirac y) busted it.
Acetone reacts with the catalyst in the O2 sensor making it think it's running rich so the ECU leans out the mixture. Running lean can cause serious damage to an engine.

All it takes to improve fuel mileage is basic maintenance like he did in the video. What the video doesn't say is that any fuel left unburned is returned and reused, it doesn't go straight out the tailpipe.

I noticed that he puts 87 octane at the pump, his car requires premium gas (91+). No wonder his fuel mileage sucks. There is a reason why some engines need higher octane than others. He would more than likely yield better mpg just by using 91-93-94 octane grade.

xzinum is right, its bullshit

1. Aren't fuel lines made of steel? they tend to be exposed to a high amount of heat and I'm pretty sure the ones I changed on my parents old 1994 Ford Taurus were steel.

2. That reason is, just out of curiosity?

(not trying to be a prick, just necessarily skeptical to both those who call miracle and those who call BS)

im pretty sure acetone will completely ruin your engine

[mfkr]

So not a single one of you noticed the cat jumping out of the trunk?

[chris]

I don't know how BS the video; I've never tried it but the principle should work.
Acetone will dissolve almost anything organic so I could see the engine seals going after awhile. Don't ask me how long before the seals go, I don't know. I'd never put acetone in a gas tank, well at least not my gas tank.

What I do know is how BS the myth busters are. I wouldn't listen to a word they say, they don't know how to do good basic science. What they do know how to do is build something flashy and sell their very flawed methods. Any person who's done second year science can tear them to shreds.

They're special effects technicians, that's what m6 does, they do enough research to make sure a stunt will work, and then they do it without killing anyone. It makes for great TV. In the lab, ehh, not so much.

[Zimba]

octane is *mainly* based off the amount of compression a car is running

[ORION]

Really, I thought it was the concentration of certain hydrocarbons in your fuel.

http://en.wikipedia.org/wiki/Octane_rating

So it's the "autoignition resistance of gasoline"

Plx relate to the engines.

[Zimba]

higher compression = higher octane required, take for example a honda vtec

Plx relate to the engines.

As Zimba pointed out, a higher compression engine will require a higher octane rating. In the compression cycle of an engine, it is imperative that the ignition is done at a precise moment. Pre-ignition can severely damage vital engine parts, especially is the engine overheats at any time.
A lean mixture creates heat, heat doesn't dissipate fast enough, next compression cycle heat pre-ignites the mixture, creating more heat and so on. Luckily, there is a knock sensor that detects pre-ignition, also called engine ping. It's job is to send a signal to the car's computer to adjust the mixture and make it richer, thus cooling down the piston chamber.

Using a higher octane rating enables the engine to run leaner without pinging. The advantage of a high compression engine is to make more power out of the same volume of gas in the cylinder chamber. It does however require a stronger current to ignite it. If your car requires premium gas, putting low grade gas in the gas tank increases your chances of engine ping, which in turn will make your fuel mixture richer. A little counter productive if you're trying to save gas.

I hope this helps

im pretty sure you dont need to e-test a car if it over 20 years old..

No you don't...this was kind of an experiment we pulled at Cooksville auto wreckers a few years back. It worked...then we added some other chemicals...and watched the motor go boom.

Xzinum is winrar.

which is why i like diesels, make incredible power out of little fuel

[Mike-KT]

forget diesel, go fission!

[The Killing Joke]

forget diesel, go fission!

Damn... I forgot the diesel, and now I can't go fishin... ;)

[Xzinum]

I do believe that hydrogen holds alot of potential when it comes to making very efficient power. It's too early to tell what technology will emerge in future generations of engines. I read that in 2003, there was as many hydrogen gas stations as there was petroleum gas stations in 1903 (first Ford Model T available for sale).
