All I can say is, I've been using Shell Rotella T 15w40

I agree. Shell Rotella is one of the few remaining fleet oils that have both a CD and SM ratings. I have six gas engines and two diesels. I buy Rotella 15W40 and run it in everything.

I did a lot of research before making this decision and consulted with some friends (crew) that run agricultural equipment leasing companies.
