Regular high mileage or extended performance high mileage, the EP high mileage is actually cheaper after rebate.
I went with regular Mobil 1 HM, didn’t know the rebate structure was different with EP. a good deal none the less.

New oil and filter are in and I had it tagged and registered this morning. Wifey baby and I will take her out for a spin (including highway) this evening. This will be the first time driving it above 40. Hope it goes well!

Maybe you should take it for a long drive without the family first, JIC. 🤷‍♂️

Precisely, it's like some of these guys are in their own little world. I want to see them actually take apart an old vehicle (and all the risks entailed when things don't come apart nicely after 2+ decades) for small leaks/seeps, rather than at least give HM oil a shot. I don't know if it's an OCD thing, because it's not based on logic. If it works it works. It's not even as if it is a large price premium.
Exactly.

On my old slant 6, I've had the very best results with QS HM 10w40. After fixing the worst leak a few years ago, I had tried Maxlife, Castrol and Havoline HM's without much benefit. Some of them were 10w30's however. No obvious evidence of oil burning.
