93 (or 92 at some stations) octane - 300 miles to a tank - ive never driven to where the gas light has come on but ive noticed that when my gas gauge reads half a tank i can only put about 9 gallons in it until it is completely full -so im thinking if i have a 22 gallon tank when im on empty i could actually still have a few gallons left in there - and with the difference between an entire tank of 89 vs 93 being less than $5.00 id rather just run the cleaner stuff just to be safe
--funny (sad) how in 04 people in this thread were complaining about $1.84 a gallon
