Well, you've been running non-spec oil for two years, hopefully you dramatically shortened the oil change intervals.
There are two, and only two, Mobil1 oils that meet the Mercedes spec for your engine, 0W40 and 5W40.
There are NO non-synthetic oils that meet the spec for your engine.
Any synthetic oil that meets the spec for your engine will say so on the label (meets MB 229.3, 229.5, 229.51, etc.)
0W40 Mobil1 meets the spec whether you live in the hot desert of Arizona or the chilly reaches of Siberia. Why in a blazing hot climate a mechanic would recommend a thinner oil I can't begin to comprehend. And why an alleged Benz mechanic would recommend a NON SPEC oil for your car is even more of a puzzler.
So here's the straight dope:
Use ONLY an oil that meets MB 229.3 spec, minimum.
Use ONLY the fleece oil filter.
Follow the FSS for oil change intervals.
If you for some reason do not want to use Mobil1 there is a list of approved oils in the DIY/Help stickies at the top of this forum.
You'll save money and probably some more lousy advice if you buy a topsider and change your own oil. Plus you have the convenience of doing it when you want without driving anywhere.
Take care and enjoy the ride,
