Correct, but in the case of vehicles designed for it, such as the Fusion referenced in my post that's designed for it, the computer will automatically advance the ignition timing and / or alter the fuel map, thereby achieving an admittedly modest power increase.

In a vehicle not designed for it, it'll do all the bad things people have listed in the thread up to and including severe engine damage.

The bottom line is use the gas recommended by the manufacturer for the most efficient and best performance.

Went to the link for non-ethanol gas stations and found one not too far from where my wife works.
I called and the woman that answered said "yes, we carry ethanol free gas". I asked was it 87 octane? Her answer was, "no, it's E85".

Was her name Joseph Heller?

Use whatever octane your car is recommended for, extra octane is not needed unless you car is knocking (the knock sensor should have retarded your timing), your MPG should have dropped. Continual use of E85 for your vehicle is not recommended, this 2 time use shouldn't have done any permanent damage, as stated it is not good on rubbers and plastics in your fuel system. I would only use E85 if I was in the middle of the desert, low on gas and that was all that was available. If you want to use a fuel system cleaner, only use Redline SI-1 or Chevron Techron, these both contain PEA (PolyEther Amine.) A very powerful solvent, is considered to be the best fuel system cleaner. There may be a couple other brands using it - as it is a Chevron proprietary additive is not universally used (cost.) You can get this at a lower ratio using Chevron gas - you can get 10X using the additive. A lot fuel system "cleaners" are some sort of alcohol as the solvent so you won't be helping by adding more of it to your gas - read the labels.

I'm not. GM trucks can (for the most part) run E85. GM publishes both numbers. The power gain is because of the engine being able to advance timing. The current 5.3 goes from 355 HP to 385 HP on the stuff.

Yes it can. A car from 2002 it will eat up fuel lines and seals and stuff like that in the fuel system that were never ever made for 85% alcohol(ethanol)......

OP- try to water it down with 93 octane gasoline.

Jimmy.. You are Wrong.. any car made since 2001 has to have fuel lines that are compatible with Ethanol.. E15 which is mandated in all states has Ethanol. and 93 oct does not have less Ethanol.. Octain is no a problem with E85 is is much higher than gas. if he wants to dilute it he needs Recreational gas with 0 Ethanol.

Correct, fuel lines that are compatible with 10-15% ethanol NOT 85% ethanol. E85 will do a real number on fuel lines, fuel system seals,fuel pump and o-ring tips on that 15 year old toyota.

Incorrect on the e15 portion. Always a good idea to read the entire thread before posting (see bottom of pg 2).
