i think earlier engine manufacturers claimed a life of 100,000 miles i.e 160K Km, honda then stated to claim that their engines last 200,000 Km
lately no manaufacturer put claims on engine life perhaps may be people dont keep their cars for so long in western countries
mostly nowadays manufacturers claim longer maintenance cycles
40,000km is the longest mainatenance cycle i have heard of for a holden - no chnage required not even oil. crazy to think of but that was in a program i saw on tv - but still seems exagrated.
