I try to calculate mpg each time I fill up... on average, it's been between 26-29.
I do mostly hwy driving 85% of the time.

I tried prestone fuel inj. cleaner about two tanks ago, my mpg i must say has gone up to 32mpg. I plan on using it with every oil change.

34k miles on it now...plannig to clean intake valve..
