$1.71/gal for 92 octane Amoco Ultimate.
$4.00/gal for Sunoco 100 octane (unleaded). The ECU in my car yanks timing and boost when it hears detonation, and the hot weather around here lately has made for some sluggish afternoon driving. Next time my tank is low, I may just treat myself to five gallons of good timing.
Anxiously awaiting the arrival of a long, mild fall . . .
