I still have a ton of COOP DMO mineral 15w40 and syn 0w40, probly around 250L combined, any issue to continue running in my 2020 f350 diesel?COOP Lubes
Seriously doubt you would have any issues with it. Ford went off the rails about CK-4 and set their own specification that was not revealed until a few weeks before the debut of CK-4.At this stage of the game, they (Ford) typically states that >1000PPM of phosphorus is the limit for oils they prefer. I would run it without thinking twice.
Thx gents, I'll keep running it, mineral for the summer, syn for the winter. Still has the 10w30 factory fill, will be doing UOA's with every change. I have a dozen or so sample kits here. Cheers!
x2 Looks like a good blend. Phosphorus and zinc are above 1000 ppm. Decent bit of boron as well. That is from a uoa i found posted in 2012. Assuming they didn't change the formula....
