Why do you think you need a high mileage oil? Do you have leaks that they are staving off? Generally, that's what they are geared toward. The Mobil 1 HM oil you ran doesn't have higher levels of AW additives than their other oils for example.Re Lucas @OVERKILL, @tblt44 and @fantastic - I do prefer 18cst and I’d be open to try a: a) high mileage b) 50 weight c) synthetic oil - but I’m not aware of an oil that’s oil 3. So I’ve been adding Lucas High Mileage Oil Stabilizer to Mobil 1 10w40 High Mileage and my UOA results have all been excellent.
If you want a heavier oil, Mobil 1 15W-50 or 5W-50 would be just fine by themselves. But, if these are stock engines, I can't see the need for something that heavy, considering they spec'd an xW-30 when new, correct? In which case I'd run M1 0W-40 personally, but their new Euro 5W-40 is also another solid option. Both of these have considerably higher levels of AW additives.
And yes, good for using the FRAM Ultra, lol. Nice to see it was a wire-backed OG filter.
