also i drive about 700~1000 miles a week. i get my oil changed twice a month, and i can put id say about $15 in premiume gas drive all the way to hwy 16 in griffin ga pass summit racing and back. my gas light wont even be on when i get back home. at most thats about 120 miles to and from work mon thru friday. if you include the weekends, its around 1k ah week. i would say i get pretty good gas mileage in my car or else i would have been quite and found ah job closer to home.
