M278 High Mile.
Besides normal service and oil changes every 12,000 km, both turbos have been changed at 387,000 km, and 2 times Airmatic bladders.
Still really nice compression, and the oil consumption is not alarming compared to Mercedes specifications.

Congrats, that's quite an impressive distance and I wish the best to your engine for the leap to half a million km !




Actually....what is original? Car looks great, though. Clearly taken care of. Proves that "miles" aren't necessarily hard on a car. Disrespectful people are.

The Best of Mercedes & AMG



I'd like to give my engine the best chances to go as far as it could so I'm curious to how people do it.
