That's pretty amazing you ran 10k on dino. I'd be scared to death to do that. I cringed when the PO of my MGM told me he would occasionally go 7k miles, just because he didn't feel like changing the oil (I can understand that, lol). I guess I'm just so used to the picky nature of the 3v Modular like what's in my F-Series pickup that makes me want to be such a nut with maintenance, especially on Modular V8s.You can easily triple or quadruple the 3k mile OCI in those cars ...
Please read these reports of my two MGMs before you say I'm a heretic.
5w-20; Ford 4.6L engines; UOA testing

Those engines don't care one hoot about what lube is in the crankcase nor what filter is hanging off the side of them as long as the products are reasonably selected for the application. The Ford 2v mod-motors will last nearly forever with anything from 0w-20 to 10w-40 and everything in between. And as far as filters go, the hypothesis here on BITOG far, far, far exceeds the proof about how much filter differences matter in short to moderate OCIs (15k miles or less).
