leaded or unleaded fuel

All he has done is lowered the octane from 110 to 98.6

((3/5)*91) + ((2/5)*110) = 98.6

Doesn't make any sense to me

Should be no reason to not run 110 leaded UNLESS he has a Cat Converter (other than cost)

I know why I added pump gas to race gas... Expense! LOL.. race gas is 9 bucks a gallon... If I could get away with only having to use one gallon per 4 gallons let's save quite a bit of coin over a little bit of time...
