Engine oil

Tom- is it possible you have a slight oil leak that is giving you that smell ?

Rotella has it's very own distinctive smell..
 
I don't see the Ford Powerstroke approval. Am I overlooking it? I thought we determined that T4 met the Ford spec?
 
Cpurvis- IDK about Fords. But I read this.

I don't have a Ford Powerstroke, either, but I have a friend who does. That's what got this whole thing started--I bought him a case of Mobil Delvac only to find out it didn't make the Ford approved list. I don't even remember what made me look into that but I'm glad I did. I'd hate to be responsible for the demise of his Powerstroke.
 
Well, your heart was in the right place.. I think Ford /like Harley would prefer to sell their 'own' brand of oil, or pay to be on the approved list. They do that with Dexos approved for GM oils.
