E85 Performance

[BlackJack]

For those of you that were wondering.....

E85 (Ethanol blend) does carry a significantly higher octane rating, but adversely requires more fuel to prevent leaning out.

Do not attempt to run straight E85 in an Alero unless you tune for it.

For boosted applications, I'm running a 1/3 E85 mixed with 2/3 91 Unleaded, and trust me, makes one hell of a difference. The new turbo set up ran pretty well on 91, but once I dropped in the E-85 mix, the estimated octane boosted to 97 points, and it ran like a pure bat-outta-hell.

Coupled with the fact that the E85 cost $1.75 per gallon here, and 91 unleaded is about $2.85 per gallon, the mix also saves a bit of money.

Let me say this one more time DO NOT ATTEMPT THIS WITHOUT RETUNING
