Hi, I own a 2002 Cadillac Seville SLS 4.6, bought it on 36000 miles it has 46000 actual miles in 9 months. I've been checking the oil level periodically (weekly) and it seem to need at least half a quarter to a quarter of oil every other week. Driving on normal conditions. I don't see any leaks and no smoke any color coming out of the exhaust. The car runs great, a friend told me it could be the head seals but I don't see any oil on the engine either. I don't know what else to do.
