Background:

This ties along with FMS VI (and a later un-named article).
Your gas mileage could be great! It could even break the laws of physics... By sucking and blowing at the same damn time. But either way, we definitely need to increase it by any means possible. Gas is getting expensive...

Theory:

Gas additives... All either use something to raise octane, clean the fuel system, or decrease the surface tension of the gas.

Why not use high octane? Because higher octane creates less power... It is *MORE* stable. The only reason to run HIGHER octane, is to be able to run MORE ignition advance than you could without facing detonation (pinging/pre-ignition, it's all the same)

Why not clean the fuel system? Because a $5 can of seafoam does that extremely well!

Let's decrease the surface tension of the gas!!!

This means several things:
It will pump slightly faster, and transfer/expel heat slightly faster. Both of those are so small, it's negligible.
It will atomize better when it leaves the fuel injector. Here's your gain folks!
Fuel will also break up better every time it hits the wall on the way to the combustion chamber (for that matter the valve too)


Instructions:


Mix acetone in a 2-5oz per 10 gallons of gas ratio.You'll have to find your sweet spot (mine is 3.5 in my 3vz-fe, 4.5 oz in the '99 4.6L f150 and 3 in mom's '02 maxima) We want 100% acetone (nail polish or real, the fragrance in nail polish doesn't bother us).
16 oz of nail polish commonly sells for $2.50. 32 oz of Acetone goes for $5-6.5, One Gallon $10.
Acetone doesn't eat away any part safe for gasoline. While being readily available, and cheap enough to pay for itself.

This lexus gained roughly 2 mpg from it. The F150 went from 17mph (avg) 19mpg (best ever seen) to 20mpg (avg) 22.5 (best ever seen). Mom's maxima went from getting 27 (avg) and 30 (when i drive it on long, all highway trips) to 31 (avg) and 35 (long trips)

If you only get 10% on 19mpg, that's an extra 35 mile range (5 miles more than the distance between your low fuel light coming on, and your ECU ****ting your engine off before the fuel runs out) A gallon of acetone will pay for itself in a tank or two. Maybe faster. (someone on a forum reported a prius going from 44/47, to 55)

I challenge everyone to give acetone at least a 16 oz bottle's worth a try! That's the cost of only one gallon of gas in a lot of places now...

Will I run into any problems if I try this while using 10% ethanol fuel (89-90 octane rating)? Also, where is the best (and cheapest) place to look to purchase a gallon of acetone?

 

I think A beauty supply store might be your best shot.

 

Is acetone actually safe for an engine? Or will I be getting better MPG because the fuel systme won't be able to use as much fuel because there's acetone in the way?

 

Damn, that sounds risky. Any research done on this. Scientific like, that this will not harm the car? How long have you been doing this? Thanks

See, acetone is highly flammable and it's used for making plastics. So, I don't really know how safe I'd feel putting that stuff into my car. What if it dries out and doesn't clean itself out of my fuel system?

 

if you don't feel safe using Pheonix's MPG trick.. just go and get yourself a bottle of fuel injector and put it in the gas tank... i bought a bottle of Mystery Oil and i recall it has acetone.

edit: Pheonix knows his *****, i would trus his idea. i will try this trick in a few month right after i'm done using this mystery oil(i got 3 bottles)...

 

Oh i believe Pheonix knows his stuff, but i'm just a little skeptical of putting an unusual chemical into my luxury car's fuel system...

 

I think i'll wait for when I get a hybrd to save on gas. I have f#cked up way too many things in the my past. Sounds like a very good trick...
