Z71 said:OEM's typically buy low cost and sometimes low-quality oils from lubricant manufacturers, put their labels on them and send them out for distribution at dealerships. Contrary to consumer perception, OEM lubes often are equal to the performance quality of the cheapest aftermarket oils on store shelves. Dealers can command higher prices simply because the consumer perceives it to be more appropriate for the application.
I imagine that there are companies out there doing that but that's not the case here. To look back just a few years ago Case-IH had a warrantee on their tractor engines for 5000 hours. I often see people here on this board saying that is all the life to a diesel engine. To say that they have a better blend then the average shell rottella, you bet but shell does have some better grades than rotella and when you get up to that quality of oil the shell is about the same price.
The goal of the company when they designed the 300 and 400 series engine was for 3000 hours full throttle full load. For theie gas engine it was 1500 full throttle full load.
