Damn...Kinda figured too good to be true...

I wonder if they ever did the crystal on the fuel line thing?... I remember when I was a kid (in the 70's) the hippy dippy types claimed that the energy from a pure crystal strapped to fuel lines would help mpg

Totally bogus to me but another good Myth Buster challenge

I have a 2003 5at sedan and ran it in there a few times (2.5 oz. to ten gallons) and went from 21 -22 mpg to 24-26 tried acetone in my 1990 ranger 2.3 liter 5 speed and every time i put it in I got 4 to 5 miles to the gallon more. But I'm too tired to do it anymore.

Does it take a lot of energy to do this or something?...

It takes hardly any energy to do this, I was just making fun of dTor's response. I've heard it works alot better on the old carburated vehicles by the way the ranger I added 3oz. per ten gallons

On my old mustang I added 1/2 a gallon of acetone to a full tank(about 15 gallons) and didn't notice anything except my injectors began leaking.

1/2 gallon=64 ounces per 15 gallons. Wow! Suggestion is to put 1-3 oz per 10 gallons.
I will try it on my dads 96 Mazda and see what happens. He is getting new car anyway soon.

Tried it and the results were inconclusive.

lol, what a coincidence...that episode of Myth Busters is on right now and I'm watching it lmao....Acetone was busted btw

On the other hand, used cooking oil was proven to be a ligitimate substitute to gasoline.

Funny! I just came here to say the same thing... in fact Acetone lowed their MPG slightly... but the farmers pants did explode from insecticide (or something)... It's a re-run I forgot I had seen in.
