93 atleast... sometimes 100 at the 76 station if i'm going out to abuse some people on the weekend

 

Forgot to mention: If you are going to store the car for a while, premium fuel will degrade slower then regular. Course, stablizer is helpful for this too.

I won't specifically say what company i work for, but this is standard practice for machines that must be filled with just enough fuel to move them in and out of warehouse before going to customers, sometimes months later.

 

regular here....i also used premium like once or twice and saw somewhat of a difference...but not really....so yeah....
