you only NEED to use what is called for on. some people use premium when not needed, and are pretty much just wasting money. i, on the other hand, NEED to use premium in my 03 expy!

It's the Octane number that counts

In the intermountain area, regular drops down to 85 or 86 octane. Personally I find that the owners manual recommendation is accurate: 87 Octane works well. I get some pinging at 85 octane.
