    Mobil 1 HM 10w40 Stops Rear Main Seal Leak MB E320

    I bet you would not notice any difference between the 5w30 and 10w40 in cold weather. I'm running M1 15w50 in my 1993 Volvo 240 and literally there's no perceivable difference between it and 10w40 or 15w40. Your car specd a 30 weight when the engine was new. I maintain that any such engine...

    Fix the air intake leak, switch to Mobil 1 5w40 and a new OEM filter, drive for 5k then change the oil again, send a sample to the lab and report back.

    Mobil 1 HM 10w40 Stops Rear Main Seal Leak MB E320

    I have a 2001 Mercedes E320 with over 280,000 miles, it had a small RMS leak and I tried adding 2 cans (600ml) of LM Motor Oil Saver to the 0w40 that was in the engine. Small RMS leak remained. A few thousand miles later it was time to change the oil again, that time I installed 4 quarts of M1...

    Best Additive For Small Rear Main Seal Leak???

    Mobil 1 0W-40, 10105 miles, Infinity 3.5L VQ35DE

    Originally Posted By: Koz1 I would try 5k and 0w-40 after looking at that report. Why not M1 10w40 high mileage? I bet it'd reduce wear across the board compared to 0w40.

    Actually the first 2 UOA are mislabelled above. This is correct:

    So the oil I installed after this UOA was a 50/50 blend of Mobil 1 10w40 High Mileage and Mobil 1 15w50 and the Pb plummeted:

    Try Mobil 1 10w40, I bet it brings the Pb down. I had high lead, switched to a 50/50 blend of M1 10w40 and M1 15w50 and the Pb wear plummeted down to 3ppm from 31. Pb drop UOA image

    Pb wear plummeted going from Castrol 5w40/K&N Filter to a blend of 2 quarts M1 10w40 High Mileage and 2 quarts M1 15w50/M1 Filter. No other changes. UOA PDF
