Oil

Do you think thicker oil would be better,when temps reach 90 degrees?Thanks!

I think most oil bottles/cans list the temperature ranges that are good for a given oil viscosity.

But I'm not a fluids expert.

Just use regular 15w40. You'll be fine.

You realize your motor runs at 100*+ right? What is your question?

Agreed.

I think he's talking about 100 deg. ambient temps?

15w40 is fine. Cold has more of an effect on an engine than heat.

LO9-2320-209-12 Lubrication order for all variants of the CUCV

I do not think you can go wrong with any diesel specific 15W40. Most if not all diesel specific oils today exceed the requirements of the original spec oil.

Thank you everybody for the help. I will go with 15W40.
