Car dies on the highway.. engine possibly trashed??

[Eric***]

I always change my oil twice a year, no matter how little I drive, or every 10.000 km anyway. This despite the car manual only says oil needs be changed every 40.000. Also, whenever I start a trip longer than 200km, I check the oil and add a little if it's dropped any.

I've started doing this less than 10000 km / 3000 mi, since the manual does indeed give more room.
