What type of oil?
I live in NJ. On my wifes c240 we have been using 0w-40
The car has just a little over 100k
Approved engine oil viscosity in relation to temperature
Below -13°F/-25°C to Above +86°F/+30°C 0W-30, 0W-40.
Above -13°F/-25°C to Above +86°F/+30°C 5W-30, 5W-40, 5W-50
Above -4°F/-20°C to Above +86°F/+30°C 10W-30, 10W-40, 10W-50, 10W-60
Above +5°F/-15°C to Above +86°F/+30°C 15W-30, 15W-40, 15W-50
Above +23°F/-5°C to Above +86°F/+30°C 20W-40, 20W-50
So when I first purchased my 2003 E320 I had the stealership do a "Service B" and when I looked at what type of oil they put in they didn't put in the MB oil but Mobil 1 5W40.
I live in Northern California where the temperature stays pretty much in the mid-range between 30 and 100 degrees. So the 5W40 will work in that temperature range.
I figure if it's good enough for the Stealership then it's good enough for me.
You might want to have the Stealership do it once and have them do a service and at the same time to make sure that everything is working correctly. Then observe the service sheet and see what type of oil they used.
You can also save money on oil changes if you choose to do them yourself. But be sure to not neglect all of the other checks that need to be done at appropriate mileages.
Here's a good link for DIY oil changes. This guy Check Codes did his homework and provides good directions.

Good Luck and happy motoring!!!
