Probably time to change the oil.

I mean technically you never need to change the oil on any car if you're willing to just drive it into the ground.

  I wonder how long a full synthetic could run in an engine that, for whatever reason, doesn’t push oil hard. 20k miles?

    You can find these stories in the mechanics subreddits, typically it's some Toyota came into the shop dying at around 60k miles with the factory oil turned to sludge.

  What I omitted on purpose is that Ive also only driven it like 4k km during that time period ( ･ั ﹏･ั )

    Oil is a consumable with both a use lifespan and a time lifespan. So it needs to be changed at the lesser of either of those intervals. Same with tires, which a lot of people don't realize.

      True, and I'll probably have to change it soonish, but 5 years/4k km is not in a problematic range.

Motor oil is a wear product with a lifespan. It will become saturated with microscopic particles of metal and end up with lower lubricity. You are just slowly grinding away all the metal off the moving parts. Eventually the tolerances will fail, usually a rod bearing, leading to self-destruction of the motor.

“I haven’t brushed my teeth, but I don’t have a cavity - so I’m good”. Don’t get me wrong, my “fun” car (an old, beat up Jeep) is going on 2 years with the same oil (I barely drive it), but I known I need to change it soon. Oil degrade with oxygen. Every time you drive that car, the oil are being re-oxygenated and continuing to degrade (along with being exposed to combustion byproducts). Also, the type of wear you get often isn’t noticeable until it becomes catastrophic. In my case, a 30 year old car that’s already on its last legs “catastrophic” is more like “time to finally drag it to the scrap yard”.
