Hi Folks,
I just had my 3 cylinder 201 cid diesel engine rebuilt for my 1971 Ford 4500 TLB. I had been using Rotella 15w - 40 oil which I thought would be fine for a 45 year old diesel engine.
Now that the engine has been completely rebuilt I see that the Ford owners manual recommends SAE 20 for temps between 32 - 90 degrees. Does anyone have any suggestions, thoughts or recommendations on using a 20 weight oil on a newly rebuilt engine?
Thanks,
Ray
