Have you ever worn out an engine?
I read recommendations made about the value in changing oil. I have been operating roughly 20 diesel engines at a time over the last 30 years. Some are 40 years old and still running. I have a Cat C15...

I have once.......or sort of. 69 Chevy 350 changed oil at 3,000 miles on the dot. At 100K the cam went flat.
Pulled the cam and my dad made the decision to rebuild the engine while the cam was out. New bearings, rings valve job and timing set. It ran for another 150K before I sold it.
My 6.5 has 170,000 on it and runs like a Rolex. 7,500 oil changes.
No oil between changes except when towing in hot weather.
My LBZ has 70,000 on it and runs like a Rolex. 10,000 oil changes. No oil between changes.
Case tractor has 10,000 hrs + on it. 100hr oil changes. Runs like new. No oil between changes.
Mazda has 300,000+ miles on it. 3,000 to whenever I get around to it (maybe 8,000 mile) oil changes. Runs like new. No oil between changes.
I have many more but it's all the same story. In all the engines I have been around I have yet to see an oil related failure of one.
I have heard of a guy that leased his cars and did not change oil in them. He got burnt on one at 70K. The shop I worked at in the 80's pulled the pan and my boss said the oil looked like tar and it clogged up the pickup screen of the pump. They rolled in a set of bearings, cleaned out the tar and off he went back to the lease company. I believe my boss said he still came out ahead of the game by not changing his oil.
