I did a search on this but couldn't find anything:
My car as always burned oil as long as I have owned it, but I have recently noticed a trend in how it burns the oil.
When I first change the oil, it will go about 300 miles before I need to add any for top up - about 4-8oz. During the next 300 miles, it will will require another 12-16 oz. Currently about 1/2 way into the 3rd 300 mile period and already added another 1 qt of makeup oil (for a total of about 1 1/2 qt at about 750 miles).
I think it is strange that the oil usage is not uniform, that it starts of not using any oil when it is fresh, and then requiring increasing amounts of top-up oil as the mileage accumulates.
I am in my 2nd AutoRx clean cycle on this car, and I am beginning to feel that is is a futile excercise as I can't keep oil in it long enough to do anything. The oil usage rate has been relatively unchanged for about the last 2 years, and I've tried what seems like everything short of rebuilding the engine to clear it up.
