I have always heard that don't quote me on this but, The gas mileage difference in 87 and 93 actually equals itself out, not to mention a lot less carbon buildup. Not to mention I think I would feel bad putting anything but 93, Like giving your kid spoiled milk or something!

i only see 87 89 and 93 everywhere i go. the manual says it needs 91 but i always get 93.besides if you dont run the right octane over time it screws up the engines timing cause the octane for those who dont know the higher the number the longer it burns before the actual combustion so if it explodes at 87 octane timing in a 93 engine its obviously not timed right and youll get bad performance and eventually engine problems.
