hey whats up everybody, i got a 95 seville sls. this morning i filled up @ the BP around my way (central va) and i noticed on my way to work i had a increase of 3.5 miles per gallon w/o the cruise control on (because it don't work). i usually go to chevron and fill up. i got 2 questions: does anybody know anything about BP new gas called "invigorate" and does driving with the air conditioner on have anything to do with gas mileage?????????
