oh no, without top-tier gas how did cars work years ago!
Little crazy folks. Throw in some add once a year to clean and maybe some MMO to gain MPG and be done...I have used FP and FP+ but MMO wins for mpg gains.
I have used Citgo, Flying J, Mobil, BP, Shell, Pride, Hess, BJ, Stop and Shop, Conoco and a few others.... and auto works great...
