Hey guys,

Has anyone opted to use 87' or 89' octane to experiment the difference (extra 10ft-lbs w/Premium) in torque with the Premium grade vs. the lower grades?

I haven't gotten my Mustang yet, but will arrive on Saturday!! It's still on a railcar! HURRY! HURRY! HURRY!

Honestly I don't notice any difference except in the amount I have to pay.

Maybe you can notice a difference if you get a tuner for the car....

I noticed no difference either, but I will be getting a tuner shortly so I've been using 93 in preparation.
