Which oil next? Experiment on 2018 Outback

I’m under 1,000 miles on my 4th and final Valvoline R&P oci on my 2018 Subaru Outback oil burner(130k). Full details and results coming soon!!

My next uncontrolled experiment will be to run an OTC oil long term to see if my rings stay clean. I’m willing to be a guinea pig here.

My question for you is out of these two oils easily available at Wally which would you like me to use for the foreseeable future?

Mobil 1 ESP 0w30 (I currently use in many vehicles)

or

Mobil 1 EP HM 5w30
Mobil 1 ESP 0w30

I would try both, then pick the one you "feel" worked best overall including data input for fuel mileage and usage.
In your analysis use 65% weighting on metric and 35% on touchy-feely.
I would be inclined to start with the EP HM.

Side note: It took a while to settle in with the add pack changeover, but my impromptu Mobil Frankenblend is doing very nicely in My Ford. That be a majority M1 5W30 and then 1 qt M1 0W16 added over time to thin the sump a tad. This is a 5W20 oil cap motor.
