According to the owners manual, you should use only 91 octane. By the way, where do you live that you can buy 91 octane, all they sell here (texas) is 87,89, and 93? mike_fm2002 <paul.sweet@xxxxxxxxxxxx> wrote: What octain level of gas should I be using, 87, 89 or 91? Will the engine run better at higher octains, or am I damaging anything by using one over the other.
