My 2008 500GT was picked up yesterday with 5700 miles on it now. The owner was far from a hot roder but a collector. He says the oil was changed 1000 miles ago. which was about a year and a half ago. I do not doubt him as he was miticulous in explaining every little thing about the car, good and bad. The dipstick shows it to be 1/4 to 1/3 of a quart low on oil. This is concerning to me. I have no way of knowing the level immediately after the oil change so it may have been slightly under full at that time already. It does not smoke, has no leaks etc. Maybe I am to much of a perfectionist but fret about things like this. I have a 2006 GT that uses a quart of oil per 5000 miles which I am not happy about either. What is your experience regarding this issue?
