First of all, its important to establish which engine you're talking about.
Myth #1: This engine will go a million miles! Ever come across a Craigslist ad featuring an old rusty diesel w123 or w126 Mercedes and they're asking an exorbitant amount of money based on a 'bulletproof, million mile engine', extreme mileage, 'runs on any oil', etc? Well I'm here to set the record straight.ĭespite the main aim of this article being the w123 and w126, the logic outlined in this post pretty much applies to any Mercedes diesel up until the late 1990s so.
