Maybe over emphasis on city cycle in cold weather? May no longer matter since the base oil development has continued apace.

Maybe we're approaching the oil technology era where almost all of them are so good, we're munching on the very corners of a discussion (assuming suitable OIC)? Fortunately the combination of MPG and government involvement has provided a target for the discussion - thin vs thick. :-)

Agree for sure - so, it "could" be correct, or accurate enough? Not trying to argue the point, but was looking for simplicity.

OK - how far "off" are the AI data? Substantive, or minor? I recognize accuracy is important, but was looking for an easy way to get "close enough."

Sorry - didn't realize core use was an issue.

Do you have the actual manufacturer numbers to allow for comparison? I mean, something published by Mobil? Trying to compare and contrast a few things.

OK , so now have about 2000 miles on the 0W-30 M1 ESP ... can't detect any change, but wasn't expecting to 😇 Just ordered and received another 5 qt jug from Wally ... Wix 57055 XP filter.

Doesn't BMW STILL have issues with valve stem seals? Across almost every engine?

Or, just suction the oil out ... my change is about 15 minutes now ... don't even get dirty!

So, no issues with the Ascent CVT using Castrol Transmax Universal? Would be great to see you post on the ascentforums.com site.

2021 Subaru Ascent - ran 0W-20 until out of warranty then switched to Pennzoil Ultra Platinum 0W-20, then Pennzoil Ultra Platinum 5W-30, then back to Pennzoil Ultra Platinum 0W-20 (I had an extra job), then Mobil 1 ESP 0W-30. Can't tell any difference - except MAYBE the Pennzoil Ultra Platinum...

After 43 years of storage, BSA 500 Goldstar B50SS Return to Flight with two changes of cheap Rotella T4 (15-40), then changed to Castrol Actevo 20W-50 syn blend. OK - I have been working on it for the last three years.

Actually, since 2023 model year, the Ascent manuals recommend 91+ octane when towing - says something related to reduce temps, etc.

Would certainly default to Pennzoil Euro LX 0W-30 if easy to buy here - but would require $44 for 6 quart bottles, vs $28 for 5 quart bottle. Just too easy with the Mobil 1 ESP 0W-30.

Agree and would except it is more difficult to find and more expensive - like $44 compared to $27.
