I've been using Mobil 1 0w40 for the last five winters. I change to M1 15w40 for the summers. I live in Northern IL. My 83 300D has 192, 000 mi. on it, and I've put about half of these miles on as the second owner. When I got the MB even after valve adjustments, gp changes, etc., I had trouble starting it in sub 25 degree weather w/o it being plugged in. After changing to M1 0w40 and keeping up with the maintenance, since I changed to synthetic, winter starting has improved greatly over the dino stuff. BTW, I may burn 3/4 of a quart of M1 every 2, 500 mi. And...............the car has quieted down greatly. Just my experience. MikeN
