In sunny SoCal, the best price I have found for 87 octane Standard/Chevron is $1.55 - most places about $1.65-69. About a dime higher for mid grade 89, and ditto for not so high test 92 octane. The cheapest ARCO (what's that pinging sound?) is about 3-5 cents less, and COSTCO or ultramar is about 2 cents less than ARCO. Of course, all the gasoline is liberally laced with methtertbutylether oxygenators, which we were told made the gas cost more when they were first added. Now that they are being taken out, you guessed it, it is going to cost more to remove it!
