I know the book says regular is fine...but is it a good idea to use a higher grade? Keep the engine clean and run smoother? Maybe better MGP? :?:

More discussion of this topic here:

I tested premium and regular unleadeds on 10 tanks (5 of each) alternating and could not detect a difference in either performance or mileage.

Others tested this (discussed in the Yahoo! forums) with a dynamometer and OBD-II setup and found no difference in power with premium IIRC.

Use regular.
