That OCI plan in mind, you might as well buy the least expensive HDEO you can find on sale each time, because your short OCI plan is NEVER going to use the whole capability of any oil, regardless of brand/grade you select. Therefore, if peformance is not an issue, then price is. Just know that 5k mile OCIs in a Dmax is a total waste of money, no matter what oil you use. At the very least, I would suggest using the OLM, and the low-cost oil of your choice.

We need to put that link to the GM OLM discussion up so these folks can develop some confidence in it.

I think most people still think it is simply a mileage reminder.
