"93/94????? we can only get 91 here in california..... the only way i can get the proper fuel for my mustang is buying trick which is expensive..... luckily its not my daily driver anymore"

Another good reason not to live in California

Here in sunny, but chilly, south central PA, we have Sunoco gas which comes in both the 93 and 94 octane varieties. Both of my cars drink the stuff, and I should probably say "guzzle the stuff", since one gets 6 mpg and the other gets 10 mpg in local traffic. The 94 blend is only 1 octane point above the other, but it seems to make a big difference in starting and running. That one little octane point will set you back and additional 20+ cents per gallon over the 93. Last time I filled up the 94 was $3.39 and the 93 was $3.16. Regualr was $2.86.

I am also pleased that neither are daily drivers.
