Acetone. Lets get to the bottom of this

[Nerys]

Acetone is a moot issue anymore. There is no possible way for the average person to determine if its DOING anything or not. The Ethanol in the fuel screws up the average cars fuel economy to such an extensive and VARIED amount that you will never ever know if an increase is due to acetone or you got lucky and got less ethanol.

My Cherokee used to get 22 city 24 highway reliably and consistantly.

Now I get 21max highway (4% ethanol) but usually 18-19mpg (6-8% ethanol) and as low as 15mpg when I had 11% ethanol

even the SAME gas station has different ethanol content from one tank up to the next tank up. Wawa is pretty constantly 6-8% ethanol so I use them.

but even still I simply NEVER get reliable consistent MPG reading any longer because of the variations in ethanol content so any road test for acetone is meaningless since there is no way to separate the numbers to gain any meaningfull data.

ONE possible way would be for someone to buy say 200 gallons of gasoline from the same place OR mix it all up really well to homogenize it.

Fuel your car off that for at least 3 tank fulls to get rid of any old gas and keep doing that till you get consistently reliable data. THEN start adding the acetone.

200 gallons will give an average car 10 tank fulls. you will need at least 3 to clean out the system another 3 to get reliable consistency.

that leaves 16 tanks left. 4 with acetone 4 without 4 with and 4 without.

See if the data makes sense from there. Otherwise its meaningless information.

I'd be the first to say acetone does nothing for fe. But I'll also say, in the wee concentrations it is suggested to use it, I doubt it'll "dissolve" anything.
