regular here IS 87. You can either use 87 or mid-grade. I'm not sure of the number, but I guess it's between reg and premium. I've only see it on gas stations once that said "mid-grade" .... other than that.. i've seen reg, something reg and premium.

Your car is rated for 87 octane. If you notice any knocking, then either change brands or go up to 89 octane. Putting higher octane in it for no reason is just a waste of money.
