Is anyone else having problems finding anything higher than 90 octane.Everything in the Texas panhandle I have been toso far have been 86 88 90. Is it ok to use 90 octane?
I dont know when it happened, i never owned a vehicle that required premium so i never really paid much attention, I had to stop at 5 different stations when I drove the car back from Dallas just to find one that sold premium, they didn't even offer it.
im in dallas and all ive ever used in any of my cars is 93, never had trouble finding it either, werid[&:] but if they will run on 91 cali **** you should be okay
