Catch 'em early enough with PCV, ATF etc and you'll see 300K+ miles very easily. Else, some get lucky and see 200K, but most not much over 150K.
I've just sent one 'shed' to the breakers at 400K, and it still had life in it. Just so tired it was easier to be rid. Seems 400K is not that much, there's many reports of 500-600K.
