And that your engine warranty REQUIRES API certified oil.
It still does.
My choice is still dino oil and regular changes, nothing I've seen in this thread has changed my mind. Infact, there is considerable support staying with regular oil and regular servicing, and they know their Cummins will outlast them.
Obviously you have me on your 'do not view' list. If you read my posts and did the research yourself, you would see that *no* diesel engine lube is API certified, because API do not certify diesel engine lube. Thus DC cannot require it. Period. End of story.
Moderators, I believe this thread now needs to be shut down.
