It takes most PCM'* 150-200 miles to adjust the computer settings, so the engine will run efficiently on any given type of fuel. You'll often notice an initial decrease in performance when you change fuel brands/grades, but it generally should clear up after a half tank or so.
that'* only if you change onctane levels. If it'* the same octane and just low quality fuel it'll run like crap no matter how many miles you put on it. water doesn't burn so well.

I have a little over 60,000 miles on it. And as far as the ethanol additive. My manual says do not use it. Also says only use 93 octane.On a trip to Olando FL. the best I could get 29 mpg Never could get 30.

Sounds like I've been really lucky... out of the past 10 years I think I've had fuel issues twice.
