I have a very close friend, retired DC MPD, and professional driver. He campaigned Lincoln Town cars exclusively, putting 400+k miles on the last one, before trading in on the new one. Engine was still strong when he traded it.
He does/did a crap ton of idling and would often have to hustle from way out in the sticks to downtown DC, sometimes more than once. It was amazing the shape he kept his car in. Anyway, one of his religious like rituals was oil and filter change, starting at a low mileage and working up. At each change he would send a sample to Blackstone Labs for analysis. I’d have to check with him to give a guideline, but the latest report he sent me recommended 4k miles as a next interval. His numbers are --significantly-- better than Blackstone’s reported averages, I am talking 2-3 times better in some categories.
Keep in mind, that you have a low displacement, high horsepower twin turbo engine pushing a rather portly 5700 pound truck around. oil analysis isn’t very expensive and can help guide you on change intervals.
