shadetree,
no kidding....accept I never head a pinging.
talldud,
yeah, I just need to pay attention when I do a trip.
I really drive like an ol'man (no offense to you guys over 54!). Mainly because I LOVE getting great mpg!!! What's nice though is I got plenty of hp if I get in a bind.
your right about what the manufacturer reccomends. they design the optimal performance for the octane listed.
