Where do they stand? By next year, their entire line up will be DI. Yes, thus far they are "spot free". No, their trim levels are actually leaner than most DI applications.

My understanding was that 2013 C300 & C350 are using exactly the same engine, just different size of rotation wheels?(axis?sorry that exact terminology is escaping my head right now...)
From what i remember, C300 has the smaller wheels whereas C350 got the bigger ones, hence the power increase...i might have the orders backwards but u get the idea.
Please correct me if i'm wrong.
the reasoning i got from the MB techs, was so they dont have to design 2 types of engines (and assembly lines) for 2 models that are essentially the same...all they had to do was just swapping out the wheels for a particular model.
again, please feel free to correct me if i'm wrong

No..i'm not talking about the rims, i was talking about the wheels in the engine. i would assume it's the wheels with the belts wrapped around. and yes a salesman told me this but he wasn't talking about rims either.

If there are going to be issues like in the Audi, I'm not going to purchase this car after my lease is up.

I've (wife) been driving my '13 for about 500 miles now. Do you foresee any issues with this new M276 engine and our crap quality gas here? I use Shell premium 98% of the time, but premium 100% of the time. My W211 has almost 126k and is still running perfectly using Shell. No filter change.

Haha I had mine for only a month now and almost at 2000miles love the thing yes recommended is 91 octane but I have been issuing 90 there isn't much difference and I talked to the engineers and they said 90 is just fine. As far as which has station to get gas from Mercedes is not that picky. It is built to last. So as long as you use the right octane it will be just fine, all though yes shell and chevron are one of the best for fuel.

..If you look up UOA's of the tried and tested C300 after 10000 miles, the flashpoint is still around 385F and TR levels of fuel dilution. This would mean an increased probability of more intake valve caking.
You may wonder why we just don't tune our engines to run stratified injection like in Europe, but the answer is the NoX levels. If we run stratified injection, our NoX levels would be above EPA recos.

But a few questions:1) does MB rotate the intake valve (offset contact @ top of valve stem), so all parts of the back of the valve get sprayed?
2) did MB modify the pvc/egr systems to prevent sludge build up in the intake manifold, or worst case in the head port?
