Mad, some parts wear sooner, others go for 200k. (Had a friend with a Pontiac 4 cyl still running the original engine, trans and clutch at 440k miles!) Some have the right oil, the right usage pattern, the right machining tolerances in the beginning. Some don't. Certainly have had to rebuild engine from many companies/countries before their time over my lifetime with cars. Transmissions too.
I'm feeling that by the time there are enough engines in the field and experience with those engines, materials science has moved on. The next generation engines use new "better" parts and then have to go through a similar cycle before the engineers truly understand what the failings are going to be on those new parts.
