This is South Louisiana and right now it's 94 in the shade by the temp on the screen porch. It's 30 minutes to the Gulf of Mexico.

Do you think I should use octane booster on fill up even with 87 or 89 at the pumps down here or use 89 most of the time? I don't want an engine issue later.
We bought good stuff when we were working but now we try not to spend any money we don't have to and fuel keeps us moving and active to keep us from the nursing homes.

Retired, every quarter counts.
