2014 VW Passat 1.8TSI engine. 249k miles. Did the recommended oil change at every 10k until 125, then every 5 k. Transmission fluid change every 80k, looking back, will switch to 60k, just to be safe.

I did ea888 to 155k. 5k oil changes. Change the damn pcv at like 40k IMO maybe 30k. A bad pcv will give you leaks everywhere so just swap em.
Nice work. My 2012 camryil4 se gets new oil every 3k 0-20 pennzoil ultra syn. 112,000 mi.
Both of my Guzzis ran better on Valvoline. This is if you’re in USA
I like red line oils, because they have a bit more zddp which is nice for the rockers.
At the end of the day, pretty much anything in spec will work fine.
That being said, I did a bunch of research for my V85 and determined that Motorex Cross-Power does the best in high demand applications. Air cooled engines can have a really wide temp range. That's what I use.
I try and stick with Motul 10W60. But I don’t think the engines are particularly picky about brand
I had a 2017 Forester with 175k miles on it and only used factor oil and never had any issues. I did not do any off road stuff and it was only a premium model, not a wilderness model. I don’t think it matters as long as you change it regularly.
So if you review the virgin oil analysis database, it includes idemitsu 0w-20 and 5w-30 and for both, the TBN is rather weak in comparison to other more readily available blends, also, the viscosity at 9.5 cSt for a 30w, some 20w come close to that. Does any of that matter? Not a whole lot, but it shows that there's nothing special about the oil. Generally speaking, higher TBN is better.
they only say you can do that with their Mazda-branded oil. That stuff tends to be expensive.
