So for the total newbie like me. My 1st Cummins truck.
I have read about several oils... Amsoil, Delvac, Premium Blue, Delo, Dino, and Synthetic.....
Read the entire thread and still don't know what to do.
I have 4,000 miles on my 2004 HO Engine.
I guess I am not putting synthetic in it until 15k. I think I am using 15W40 in it. Doing the first change at 5,000 miles.
Don't have a clue which oils are syn or not but am gonna research it.
Can we get some of the terms cleared up... Like what is DINO?? A brand or just a nick name for Oil (non syn. )
I live in Michigan where the schedules can go both ways. I do a lot of highway driving empty for work. Average about 30k per year in milage. Only about 5k -8k of haulin. Usually about 10,000lbs on the loads. Temps range in MI per day... gotta love this state.
So can I get a FINAL answer for my 5K oil change on the name(oil), weight(oil), and filter name.
Thanks to all. New to the site but love all the tech info.
And never even thought about TESTING my oil to see what is in it... Where or how do you get that done??
