There is a racing gas station down the street that sells 94 97 100 octane gas i wanted to know the advantages of using this fuel will i get better mpg will it improve my hp just wondering kuz the 100 octane sells out here for $5.00 a gallon and thats only $1.00 extra compared to 4 a gallon
for 91 is it safe to use in a stock b18a1 with a b18c1 head and stage 2 cams
