Delo or Rotella. Your choice of straight 30W or 10 to 15W-40. Make sure it's diesel engine rated, I think they're up to CJ now. I strongly urge you to avoid synthetics. Tends to attack seals, not good, especially for the oil pan seals. I've had 15 ears of experience with our 1986 M25, similar engine.
Good luck.
