acetone improve fuel economy?

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

4.3
and i wasnt sure what was all done when E85 was used. thats why i never tried it and asked. lol
so trying it would not be a good idea?

I don't think the injectors in the 4.3's can flow enough fuel to safely run E85

ok. ill take your word for it.
im going to be putting a 5.3 in it sometime in the future, will E85 work with that?

You have to edit the stoich AFR and maybe the OLFA/PE tables... you will find that the injectors then need to flow more, so they may have to be upgraded.

What year 5.3 are you planning on putting in it? The Gen3 5.3's can be made to run on E85 with the right tune, I'm pretty sure some of the later one came already set yp for it

thanks Joecar.

We dont know on the year, it'll be from the salvage yard. any certain ones to look for?

Thanks,
