the last time i changed my oil, i lost about a quart and a quarter of oil now its been about 2500 miles since my last oil change and i check the level when the car is cold and it is a little bit below half between the two holes, then i warm up the car to normal temperature then shut it off wait about fifteen minutes and check the level again, and now theres no oil on the dipstick, wait another fifteen minutes and check again and still no oil. Does anybody know whats wrong? how can i lose that much oil so soon? i don't run my car hard very often? my friends that have b16 like i do don't lose as much oil as i do only about 3/4 of a quart every 2700 miles
