1) The engine manufacturer is only accountable to the 'car' buyer for the duration of the new car warranty ( presently Hyundai/KIA/Genesis offer a 10-year or 100,000-mile warranty.
2) Caterpillar Corporation studies there engine design within the context of, 10,000,000 miles duty cycle, over 7-8-years, with 25% 'wear' over that time span, before 'overhaul'.
3) My 1984 HONDA CIVIC CRX was at 337,000-miles when I 'parked it', in perfectly-running condition.
4) My 1994 Toyota T-100 pickup, with the 2.7-liter, inline 4-cylinder, is running well at 447,000-miles on the odometer ( I believe member BamZipPow's T-100 has more mileage than mine ) just changing the oil & filter at 7,500-miles.The rubber valve-cover gasket became very brittle and I replaced it, but the engine is basically 'un-touched.'

5) So, I'm curious as to these 'worn-out' cars, and how that's 'quantified'?
It seems like Toyota will do 1,000,000 miles ( 1,609,357- km ). What do people expect?
