That's good to know Brian- it's just like all new Toyota suv's
I accept the knock retard sensors will allow better use of premium but I have to say, "so what?" A tad more power on the 80 is like a tad more fat on a 500lb man's neck... no one's going to notice and it doesn't make any differnce if you do.

Blue Phoenix,
premium isn't any "cleaner" than regular. It doesn't clean the engine any more than regular. That is a function of additives. Higher octane makes the fuel more difficult to detonate (thus less knock and used for high compression engines).
