Hi everyone, I own two 2015 MB C400s. These cars use the 3L twin turbo variant of the Mercedes M276 engine (most nice OBDII scanners will call it an M276.8).
Now both of my cars are the same model, but their use cases (and possibly maintenance requirements) have diverged a bit.
My car only has 66K miles on it, it's tuned for about 480hp (on E30 blend which I don't always run on the street) and I do about 10-20 quarter mile passes a year. I've owned it for 3 years
My wife's car has nearly 130K miles on it and is stock. It's a highway warrior racking up most of its miles up and down the Atlantic seaboard and I-95 corridor. We've owned it for 7 years.
Under my care both cars have only ever had Castrol Edge Euro 5w40 changed annually (mine is usually at 7500miles hers is usually at 12K) with a MB filter.
I'm thinking of moving to a different lubrication solution for each.
Items to consider:
1. These engines are quad cam, with a single roller chain for each head, one for the oil pump, and one for the crank to an intermediate gear... so lots of shearing probably.
2. Two turbos (they get HOT)
3. Gasoline direct injection (though I don't think LSPI is a major issue for this motor)
What I want:
1) Oil for my wife's car capable of longer OCI, say 18 mos. (Is that even possible/desirable?)
2) A system of oils for my car that would let me run a more race oriented oil for September October(could be almost a straight weight since ambient temps rarely go below 50F) and then switch to a normal Euro style oil for the other ten months without fear of additive clash.
So what oils am I buying?
