Should I run 93 octane in my Z?
#2
93 all the way...even with these high gas prices. i tried running 87 one time just because i though i was saving a few pennies, my car knocked like a diesel. put some fuel treatment in it and filled back up with 93 and no more knocking after that. i feel stupid for even trying to switch to 87... ran like crap, but some may have better experiences with it. i sure didnt.

It should say on the fill/cap door "Premium Fuel Recommended". You would only save like 3.00+/- per fill up and to fix the problem with a bottle of good fuel treatment is going to cost about $5, so your not going to save $$ at all. Use the good stuff.
