Agreed.Looks good but I would say not to push the mileage beyond this.
Thanks - I think I'm comfortable sticking to 7.5k.Looks good. I would do 5-6K but its your engine. Who needs the boutique oils.
What would be your technical reason for switching oil?It's ok. I'd cut back a bit just to be sure since a 2.1 tbn is getting there. I'd suggest switching to a any SP rated euro. I'm using quaker state euro 5w-40 at the moment, not gonna bother with 0w-20 even if I'm still under warranty.
In short it's better formulated. Better suited for the engine protection and drain intervals and there's no lspi concern with it. Costs just a few bucks more.What would be your technical reason for switching oil?
With the report showing as good as it did, there’s no sense in bumping up another grade. The only thing stopping him from going farther is TBN, and the shelf Euros don’t address this either. Short of name dropping the only oil that could likely double or triple this OCI, OP looks fine to use what he’s got, and stick to 7-7.5k changes.In short it's better formulated.

Uh yeah.. standard pcmo fs 5w-30 definitely has the same drain interval potential as any euro oil with a3/b4, mb 229, vw 504, porsche a40, and bmw ll-01 for ratings and clearly wouldn't do better tbn and tan wise after an equal run...With the report showing as good as it did, there’s no sense in bumping up another grade.

Unless he’s going to go all out with an oil with >11 starting TBN, nothing the Euro oils will do for him justify any additional spend. The oil’s still in grade. Iron wear is 1ppm/1k miles. Insolubles 0.1%. Flashpoint is a little low at 395*F and TBN just above condemnation limit… OP is perfectly justified to continue on current plan; there’s just nothing that will be measurably improved by using QS Euro 5w40… the data doesn’t support it.
