I just had an oil change done on my truck. Chevron Delo 400 SDE CK-4/SN oil.
It says on the jug that it meets Cummins specifications.
In fact, it meets nearly every engine manufacturer's specs EXCEPT Ford!
Fact is Delo engine oil never met Fords internal oil specification which has been around for years.
Just be aware that the Delo has a maximum of 800PPM of Zinc and Phos due to the API SN gas rating.
