Okay, could somebody do the math for me? Max octane rating for an SVX is supposed to be 91, right? In Kentucky, you have thee grades: Regular, Plus and Premium. Regular is 87, Plus is 89, Premium is 93. What mix of 93 to 87 would I need to get 91.
I know I'm splittin' hairs, BUT, this 80 mile per day round trip is killin' me.
