It seems a lot of folks have been "easing" onto extended intervals, but I'm thinking since I received good feedback that I'm fine to increase as desired/possible.
I'm thinking I may run to 0%, reset, then run to 50% this time, if I don't pump out UOAs in a few interim mileages. With over half the TBN present, among other results, I'd imagine, all things constant or about the same, I should be in plenty good shape to run at least that long.
Changing the filter every 3k probably helps too, but that's my personal choice.
