Obviously if u want run e85 u have to have a piggy back or a stand alone EM tuned to run the stuff. So as far as injectors go i guess u just need larger injectors or specially made ones?? Then all the rubber components i guess need to go as well?

Right now I run 10% ethanol and have been doing it for years. The premium I run is 94 octane 10% ethanol and my celica runs great on it.

Now if you were to run E20 or E30 in a non flex fuel vehicle would there not be enough petroleum based fuel in there to keep your engine running and keep your seals happy?

 

I've read alot of interesting viewpoints on here about E85. What seems to be missing is that the '07 4.7L Engine should have a "P" code as the eighth digit in the VIN #. Not sure exactly what the difference is in terms of E85 readiness, but have read elsewhere that it involves different materials in the fuel lines, seals, and perhaps even stainless steel in other parts. It would also involve a different programming curve to suit the higher alcohol content. The Flex Fuel 4.7L engine is coded EVD rather than the standard Magnum EVA, which has a VIN # eighth digit of N.

 

That's good info roadrnr, thanks for adding that

 

You have to ask yourself if Ethanol is OK to use in an engine that's NOT flex fuel, then why does the manufacturers warn against using it in the owners manuals?

The car companies have been producing a limited number of flex fuel vehicles for years such as the Ford Tarsus, but in '07(I think I'm correct on that year) every vechicle that came off the assembly line is flex fuel. When the government started heavily subsidizing the ethanol production, they saw the handwriting on the wall and started building everything as flex fuel. Manufacturers can even void your warranty if you use E85 in a non-flex fuel vehicle because even they know the damage it can do to the fuel system.

 

I was thinking about giving E85 a try, so i researched it and the all effects on my 5.7 Hemi engine. lucas oil has an additive to counteract the bad effects on fuel system, one bottle covers 60 gallons for just under $10. But... with the drop in mpg's, the price for the additive & price difference in virginia (60 cents), I might save $1.00 per tank-full. Not worth it for me.

 

generally I only get the stuff if I drive by the station.

The bad thing is, e85 is an alternative to gas and the government is trying to push it as a replacement, but the cost is heavily related directly to the cost of gas. Gas goes up=e85 goes up. Whats the point of using an alternative if its just as unstable/expensive as gasoline
