Gas, which one?
My question is around which gas grade to use: 87, 89 or 93. 90% of my driving will be back and forth to work, 60 MPH for about 40 minutes one way. Due to the differences in cost on gas grades, what our your thoughts about me running 87 or 89 for my driving habit? I gassed up the other day and out of habit I put 87 in. I am not hearing and enginee noises. [2020, 370Z Sport Touring]
