I guess my oil usage isn't really something to be concerned with. All my car knowledge and experience has been on gas engines. As everyone knows constant blue smoke is generally a sign of bad rings, so naturally I was concerned. With my car, even when I really get on it, I don't get a cloud of smoke. My folks were up for Thanksgiving and while they were here, I had my father follow me in his '85 300D, to see if I had any smoke. He said he didn't see anything that was noticeable. I guess I lucked out in getting a car with a healthy eng. I bought the car for $1600, that included a new Interstate battery and new exhaust flex pipe.
