thanks for that info.
I have recently changed to high-mileage oils that have "conditioners" for valve stem seals. I put in our '91 300E with 180k. It was going through a quart every 1k +/- ... since then I am using a quart every 2,000 to 2,500 miles. I am very impressed. I used Valvoline's MaxLife 10W-40.
I just changed the oil and am now using Castrol's version and I have used no oil in some time. Whew! This is great.
I will try it in the 190E we are considering.
