Mixing fuel

[Ryan]

Stupid question.

If I mix 2 different octane ratings. Will it be the average between the two ratings? Or am I wrong?

I always mixed Torco 110 with 93 premium when I was running a Red's 100 chip with 0 KR and 770-800Mv O2 readings. I always used 10 gallons of Torco with 6 gallons of premium.

Would that make a 101.5 mix?

(10 x 110) + (6 x 93) / 16 = 103.6

I missed the second part of the post. Thought it was an equal mix.

Yes Ryan, you are correct. I always put a little extra Torco in just to be safe. I used to like to run my GN the same on the street as at the track. Car ran awesome on this mix, but the O2 sensors did not care much for it.
