shell 93 is the only thing i put in the mustang, when take it home to cali in june it'll be running off of a mix of 110/91. but i dont drive it much so i dont really care about the price. not like it's gonna do any good to care.

the truck i put shell or bp or post gas in usually. 27 gallon tank and it does ok, 15-19 or so combined, depending on conditions.
