Recently coming home from school, around a 700 mile drive, I needed to stop and get fuel, stopped at a shell and tried to get 93 octane like I ALWAYS do, however they were out or I couldnt get the pump to work, either way I didnt get the fuel.

My question is, how bad is it if I were to use 87 or whatever the low fuel is or mid grade to get my by?

Paying for the premium fuel really doesnt bother me i mean come on its a couple bucks more in the long run.

Just a question really

 

It's fine if done in case of need. Refill/Top up with 93 when you can.
