As everyone knows, gas prices are terrible. I have filled my tank with 88 the last two times in an attempt to save some money. Manual says anything with octane above 87 is fine.
I haven’t noticed any significant decrease in MPG. Does anyone have any experience with using 88? Should I stop and switch back to regular, or am I okay for now?
