I want it legalized so I can get better bud for the buck. Plus, it would also lower the amount of drug related busts. However, the main reason for them to do it.... Taxes. Come on. This is what will get the government to legalize it in the long run. But anyway I need to get back to watering my plants. lol
Proceed with the gaseous chatter.

That dude's got more variables in his "controlled" experiment than an algebra equation!
[*]using a mixture ratio of about 3.4 oz of acetone per 10 gallons of gas.
[*]Target addition of acetone in an optimal ratio of ~3.5 oz per 10 gallons
[*]Type of gas used: Unleaded Plus (88 octane)
[*]Type of gas already in tank: Unleaded Reg. (85 octane); 5.140 gallons short of a full tank.
[*]Calculated amount to...bring equivalent of 3.5 oz per 10 gallons: 4.62 oz.
[*]Actual amount added: 4.46 oz
[*]On 2nd acetone run, added ~1 oz of acetone to balance fuel to the approximate same ratio
[*]To measure, used 8 oz graduated cylinder. first marking is 2 Oz, estimated a half-way point.
[*]The procedure used was inspired by

The dude lists his procedure based on a test of engine oil. He also bases his procedure on adding 3.5 oz, when a careful reading of the site recommends something in the 1.5 to 2.5 oz per 10 gallons range, and clearly stated that amounts HIGHER than that may result in actually LOWERING fuel economy.
Everything the guy did is guessing, adding some here and there to "get 'er back to the proper level", which is high for testing purposes, and then not even bothering to get his high mixture correct, and for some strange reason, using a higher-test gas.
The only thing I can make heads or tails of based on his results is to ignore his results.
I start my run-out of regular gas tomorrow, as long as it doesn't rain. I have to fill up every other day, so I'll give it three-ish weeks.
Next week will be with 1.5 oz/10 gals mixture. Week after that will be with straight gas. Final week will be with 2.5 oz/10 gals mixture, after which point I'll let you know. I've already got my container of acetone from HD, and I'm raring to go - GMC Sierra 2500 4x4.
I believe it already gets somewhere in the 2 mpg range....I dunno actually, as I've got a midget strapped to the side filling my gas tank when I put the riding crop to 'im....mebbe I'll throw 'im a pad and pencil to keep track ;)
HaRuMaN:
Adding acetone does not increase your octane rating. Octane rating is a percentage of octane present in the gasoline. When oil is refined, you end up getting hydrocarbon chains of different lengths. Different length chains handle compression better than others. As it turns out, the octane chain is the best. 89 octane gas has 89% of the 8 carbon hydrocarbon chain. (Hence the name "oct-tane".) Octane is C8H18, while acetone is C3H6O.

it's been a while since ive flown, but im pretty sure you could get 105 (or 110) octane AVGAS. so how does one get 105% of anything into any given volume of liquid? (other than using the TARDIS).
