the manual says as long as its 87 octane. but i run 89 because my car seems to run better on it. its a feel and prefrance thing for ls/gs owners

Actually, a LS/GS/RS shouldn't see a positive gain from a higher octane. Its just not tuned for it.

its not necessarily a gain in performance but the car runs smoother. i did notice if i put premium it ran worse...but my car really does favor mid grade

I heard some gas statioins mix the lowest grade with the mid grade since you cant really notice the difference

my buddys mom use to work at a gas station. and there are only 2 tanks. they low octane and the high octane. the mid grade just sucks out of the both and you really cant tell if its a perfect mix of the 2 and i doubt it would be a solid number of octane that they say. so i would never run mid grade.

Wait... What?
the higher octane will always make you engine run better but then again it definately won't hurt it to run regular either

well im theory as long as it takes up EQUAL amounts of gas from both then you should be ok. besides its also really important that you run quality gasoline. i try to avoid the discount gas places because i feel more confident the the quality of major brands such as BP or Shell.

I don't run garbage like Wa-wa, Sheetz, racetrac, citgo,...

On an LS, you have no point or reason to run premium gas. Regular should suite you just fine.
