My Hemi has a 26 gallon tank and requires 89 octane. My Jeep has a 20 gallon tank and runs fine on 87. My Vette has a 20 gallon tank and requires premium. My boat has a 200 gallon gas capacity and burns 87.
Bob, it's hard to feel bad for you...there are many other people in America that are having problems just filling up one tank.
