Will E 85 gas work in my 1988 gmc truck 4x4?
will it run ok? Before you answer how do you know it will be ok?

It would run OK if you enriched the air/fuel mixture. The biggest problem is that the fuel system was not designed to carry E85, and it would eat away all of the rubber. It also acts as a cleaning agent, and would clog up your fuel filter.
So while it may run OK, you will end up spending a lot of money fixing your fuel system afterward.

A no .. Not well . They added just 10 % at some stations . And We lost MPG and proformance on couple of r company trucks . Go to other station and MPG is right back. Not worth it till swap out all old rubber seals .Source(s): 25 yrs wrenching
