acetone improve fuel economy?

[poconojoe]

are you saying that using E85 in my 2000 S10 that isnt designed for it will hurt it?
ive always wondered. never tried because i didnt want to find out the hard way.

Thanks,

How are you going to run it, if it isn't a flex fuel motor, since it will not know to increase the fuel flow? Is your S10 a 2.2 or a 4.3? If its a 2.2, I thought all 2000 and newer ones were flex fuel
