Hi. A friend has relocated to suburban Chicago with his '81 240D, which is a non-turbo model. Would Rotella T6 5W-30 be a good choice for his occasional cold-weather starts? He intends to keep the car covered for most of the winter but does not want to be limited to only warm-weather drives.
I used to look for the CH-4 oil rating when I drove my 2000 VW TDI, but I know that designation has been superseded....and I definitely do not know what a vintage engine like his calls for and what the equivalent would be these days (I know certain current designations are backwards-compatible, but not all). The local MB dealership does not have service department hours tomorrow, which is Saturday.
Thank you!
