2.0 turbo longevity questions

[Heimkehr]

When I was researching prior to and immediately after buying it in 2020 JLU 2.0 Sahara there were two things that stuck out:

1 - when it's hot out, and you plan to tow - throw in some premium (or at least regular plus).

2 - The biggest concern I found about longevity of the 2.0 was the gumming up of the intake valves due to blow by from the crankcase venting system. I now have 77k KM's on my JLU and I still haven't purchased one of these... https://www.mishimoto.com/jeep-wrangler-2018-20l-baffled-oil-catch-can.html

At the time (about 4 years ago) there wasn't much info out there on point 2 above, but maybe others on the forum have some experience with this now?

My JLU, purchased new and for which I've done all the fluid and filter changes to date, has 80K miles/129K kms on the clock. I've a Blackstone Labs oil analysis report on hand for every oil & filter change interval. The engine continues to run as well as new, in accordance with the health of the individual metrics (wear metals, etc.) plotted on the reports.

While the 2.0T doesn't have an explicit oil catch can system, IIRC, the factory design does include an accommodation to reduce and/or redirect blow-by. Possibly my good experience thus far indirectly confirms its functioning and efficiency.

I've also fed the Jeep 91+ octane exclusively, starting on the day I took delivery of the vehicle. I barely notice the 1,400 lbs. / 635 kgs. when towing at interstate speeds during the heat of summer.
