Well...this winter I am going with a 5w40 (Rotella T) for my old Mercedes diesel. Although I live in North Carolina and the winters don't get too bad here, I thought I try this weight for my first winter with a diesel. This summer I was using 15w40 Delvac.
5w-40 or 15w-40

I just love the home test labs.
I might add you won't find me outside in 10 degree weather trying to find out what oil pours better.

The 5w40 I bought was nearly twice the cost of the Delvac. So I'll probably run 5w-40 in the winter and Delvac or comparable in the summer. I am looking forward though to looking at the new Shell Syn Blend, whenever it comes out. 10w30 and 10w40, both MB 228.31 approved!

Hi,
Oldwolf - You made a wise choice of viscosity. The engine will "love" you for it!

5W is the way to go for cold climates. Also it can be used all year.
Side question. Anyone seen T6 in any store lately? I'm still looking.
Nope. I had hoped to see it when I bought the RTS a few days ago.
Dang. I wonder how long more before it shows up on shelves.
hello oldwolf. i just returned home from cary, n.c. was working there for about a year. i concur with your choice of viscosity. it doesn't get as cold there as it does here in michigan thats for sure.
