Just got 20L of tech 2000 (walmart) 15w40 diesel motor oil.
Does this oil have the PSD Anti-foaming agent? I sure hope so, because I cant find any single oil ANYWHERE that says Powerstroke on it...

I was gonna buy synthetic, but nobody round here sells synthetic for diesels...

 

I dont know about that oil but in your diesel manual it tells you the certification letters you should have...

 

If the oil carries the API CH-I rating, it has everything in it that you need.
