To add to the random fuel/ethanol discussion...
I ran ethanol free gas from a small local station in my town for quite a while in both of my '97s. That station did not have top tier gas, however I assumed it was decent. One day I got the feeling that I used to get more miles between fill-ups before I started running the ethanol free. So for the next few tanks I filled up with top tier gas from different stations that contained ethanol. My fuel mileage immediately got much better.
My discovery was that in my particular situation, the top tier gas mattered a lot more than the lack of ethanol. I've been running top tier with ethanol for many years now with no ill effects, both trucks are still running the factory poppet injectors. I'm sticking with top tier supplied stations regardless of the ethanol content. Here's a complete list of them if anyone's interested.
