Premium only. When first got it, the engine pinged under load while using regular. Premium only for me and its only 4 dollars more per tank than the cheap stuff, so why not if it helps the motor.

93 is the highest I can get so that is what I run.

When I have run anything less than 93, I get a noticable knock. 93 is all I run and I try to buy from BP/Amoco when I can - it seems to get better mileage with that stuff for some reason.

Maybe it's just me but I run 87 in my trucks and my Maxima and it seems that it's just not lasting as long. Not a major hit but a few miles to the gallon on each tank less than I'm used to. I'm guessing it's the E10 mixture everyone is going to. Anyone else notice that?

Hope this helps.
