Hello,
I am in search of the best engine oil for my Dodge Cummins. I have ruled out Group IV an Group V synthetics becasue I do not wish to take advantage of extended drain intervals to offset the additional cost.
I am very happy with the Delo 15w40 and have received very good oil analysis with it during my 3000-4000 mile oil change intervals. My problem is I don't feel the Delo 15w40 is the way to go for winter use up here in Michigan, especailly when I unable to plug the block heater in.
I am considering the Schaffeurs, but I am strongly thinking about a 5w oil for no other reason than winter startup. The Group III oils have become affordable and offer the advantage of the 5w for cold weather startup. I would consider a 10w30, but I don't think the 30 would offer the best protection when the engine is at operating temperature.
I appreciate all of your suggestions and comments.
Thanks!
