100/ 91 Octane Mix
I typically use the Nos Octane booster, but I recently moved near the Almaden/ Foxworthy 76 station that sells 100 octane.
What would a good mix be?
I was thinking 4 gal. 100 and top it off with 91.

I think 5 gallons of 100 topped off with 91 equals 94.xx octane. You can google "fuel octane calculator" and some links will come up.
IIRC an 02 wrx has a 15.9 gallon gas tank. If thats wrong my bad.

according to the chart I posted right after the OP asked his question, 5 gallons of 100 + 10 gallons of 91 = 97 Octane
