CAMARO6 - View Single Post - Can you add 1-2 gal. of E85 to CA 91 Oct. as an octane booster?

I am in CA and all we have here is 91 Octane.

I do have a couple of 100 Octane stations near me, but at $8+ / Gal., it would be far cheaper to use 1-2 gal. of E85 to bring the octane up.

Is this safe to do on the LT1 with everything in stock form?
