how will you destroy your fuel system ? i know you need larger inj to help make up for the fuel, you need more of it, im talken like like 1 1/2 gal e85 then rest prem, in a 5 gal can

How about in said '96 Corvette? Does the same go for that? It already runs on 93 premium.

Doesn't e85 at a certain percentage eat your fuel lines?

yep, any stock or mildly modified car will have no use for the race gas. You may even lose performance.

people seem to think "race gas" means it will make the car faster, but its not like that.

the race gas is actually resists ignition to a certain point, like when you have a high compression engine, the compression alone could ignite the gas before the spark plug does, obviously that is not a good thing. therefore the race high octane gas is used.

compression causes heat, diesels do not even need a spark plug to run, because the compression alone ignites the fuel.

so unless you feel like wasting money, stick to the lower octane fuel.

from wiki, regarding e85:

E-85 ethanol is used in engines modified to accept higher concentrations of ethanol. Such flexible-fuel vehicles (FFV) are designed to run on any mixture of gasoline or ethanol with up to 85% ethanol by volume. There are a few major differences between FFVs and non-FFVs. One is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system. Another is that fuel pumps must be capable of operating with electrically conductive ethanol instead of non-conducting dielectric gasoline fuel. Fuel injection control systems have a wider range of pulse widths to inject approximately 40% more fuel. Stainless steel fuel lines, sometimes lined with plastic, and stainless steel fuel tanks in place of terne fuel tanks are used. In some cases, FFVs use acid-neutralizing motor oil. For vehicles with fuel-tank mounted fuel pumps, additional differences to prevent arcing, as well as flame arrestors positioned in the tank's fill pipe, are also sometimes used.[citations needed]

e85 can be run with the newer style gas tanks, supposedly. That would be my only concern, the o-rings are viton which is fine with e85.

I have never seen a gas station with E-85...

do a google search for e85 then try to find it localy

i have seen many gp'ers that run e85 in there gp, but they have to upgrade to 65lb inj and fuel pump, you burn more fuel to make up for the performance that you loose with reg fuel such as 93 octane fuel, so in fact your mpg goes down, but its kind of a toss up between lower fuel price and mpg, because the car i have seen run it he has a full size ic, he upgraded to 65 lb inj and converted to e85 in that he was able to drop pulleys again

What about the aluminum fuel lines and such? Or how about a fuel pump that won't ignite it?

It's not worth the hassle.

fuel pump that would ignite it ? i think you would have bigger problems if your fuel pump would ignite it lol

the only problem will be any rubber lines, not sure if there are any or not. most of the system is steel including the tanks and lines, which is fine for e85.

the only section is a small amount from the rails to the steel lines

Aha...ok so, unless I get a completely new fuel system on both cars and higher compression on the GP, e85 is a no go.

Thx guys!

hercman is right, the e85 can carry a current, regular gasoline can not so you need a pump that will work with that type of fuel (the e85 COULD allow an arc of electricity through it, and possibly cause the fuel to ignite). I am not sure if the grand prix pump would be ok or not.

Does that mean if you ran e85 your car would blow up? Well I wouldn't want to be the test mule for that!

It still takes quite a bit of work to run e85 properly, and you need to tune for the fuel. It takes more energy to burn, so you would lose power, and that is why guys drop a pulley to get that power back.

its not worth it in my opinion.

no he dropped pulleys because he added the 65lb inj to add for the extra fuel, and since he added the larger inj he dropped pulleys
