too much... haha but no really i put premium (93 octane) in the stang since i run a race tune as my daily driver (too much fun haha) and i paid two arms and 3 toes.. aka $4.08.. which is low last week i paid $4.15
and yes i run premium by choice haha id rather pay a few extra bucks for the added fun i get from driving my 93 octane tune compared to 87. the people who understand what i just said understand what i mean and why i do it haha
