I have a 39 320 which is virtually the same engine as yours for all intent and purpose. I am running Chevron Delo 400 15 - 40 multi-grade. This is similar to the Shell Rotella O_D mentioned. They are both oils formulated for use in diesel engines and have additive packages a bit more conducive to our older engines.

The concern is the modern oils formulated for gasoline engines have a lacking additive package due to modern pollution requirements.

Best of luck,
Jim
