Adding Acetone as an additive to gasoline - worthwhile?

[Lazarus]

Tom nice job with the Prius.

That a pretty huge spread on the base numbers as Metro pointed out. Also I know the acetone is diluted but I would be a little concerned about the fuel bladder in the long run. Is that pure acetone? A lot of time the finger nail remover has water in it to cut the smell down. Those that say acetone works comment that it has to be "pure acetone".

Tried it on the Del Sol
Tried it on the VX
Tried it on the Prius

In all cases, no measureable difference.

I'm sure I posted at least some of the results on GS. I'm just too lazy to look for them.

Last summer i tried acetone for two months in my 1988 Pontiac 6000 with a 2.5L . In summer driving, gas only, I averaged 28 MPG. I added approx. 36mL per 10 US GAL gas. With acetone I continued at about 28. But 1125 miles later I HAD to replace fuel injector, which also fried a transistor in the ECM, and ruined the fuel pump. The 2 cents in gas were offset a bit in repair costs.
YMMV
As a side note, about a month ago I drove this car to the scrap yard.

I did my own test adding 3oz acetone to every fill up and using 100% gas prem instead of gasohol, my avg went from 27mpg to 33 mpg, I did this test for 2 months when I had a stupid long (130 miles) mostly interstate commute and gas was $4+ for premium gas. Also, I boosted tire pressure to 40 psi (4psi under max) and I coasted as much as possible, used the cruise, left the AC off as much as I could stand it, windows up of course. My car is a classic 1991 Toyota MR2 turbo with 300k miles 5 speed epa mileage was 18+24 so I was able to see a real difference. Tried it on my wifes 99 Lexus GS400 with 200k miles and we get 2 more mpg when she remembers to use it.

Should I? Shouldn't I? Eh, what the heck:
