Hey everyone I got a quick question....Alright so I did yet another oil change today and I've been letting it go....everyone tells me that an LS1 F-Body should take 5 1/2 quarts of oil....can anyone tell me why mine takes 6 1/2?? My motor is completely stock and I have never changed the oil pan. When I bought the car it was completely stock so I doubt the previous owner (39 year old woman) would change the oil pan. If anyone has an idea...please lemme know...voice your opinions......

 

BUMP...any ideas???
