As we all know this V6 is a flexible fuel engine.

Has anybody here used *E85* or equivalent (I'm not talking about premium gasoline and some octane booster) in their engine instead of gasoline?
From what I've been able to find out so far is that *E85* is quite a bit cheaper, more on the order of regular gasoline or less. It supposedly carries a higher octane rating but alas has less energy per gallon than gasoline.
If anyone here has used it would you mind commenting on the advantages and disadvantages. Thanx.
