will it run on pump gas ?

The car loves 38* BTDC timing and on 50/50 Cam2 and 93 octane she`ll do fine, but $6.00 a gallon for 110 hurts my wallet. This is especially true in a car that gets about 7 miles to the gallon. I`ve haven`t yet been able to find a compromise with timing, performance, economy, and high octane fuel. To fill up just with 1/2 110 and 1/2 93 is about $80.00.....ouch!
