I think it is more common for vehicles to have the ability to last longer than they did then. However with the dealers telling people to change oil at 8-10 thousand miles is taking out timing chains and engines.
That and I think the oil life monitor systems really should be removed and just go by the mileage again like our fathers always did. Going by that oil life monitor is really bad and is likely the reason my wife lost her motor because the people before us ran that down to near zero. We checked the carfax, but they must not have changed the oil at a shop that recorded that stuff.
