Firstly, if it's fuel injected, there is no choke. That cold start mode is actuated by the computer. IF it has a carb on it, the choke is opened a little to keep it running with a vacuum line connected from the choke dashpot to the carb base when cold till warm-up, then a heat spring pulls the choke full open. Your gonna have to make up your mid as to whether it fuel injection or natural aspiration with a carburetor.

Straiht 50?? Are you driving in the desert....

Extended use could verry likely cause engine damage, I would stick to the genuine oil, or at least use correctly grade and type.

Mercedes usually run a synthetic 5w/30 or 10w/40..

run the fault codes and look for TCM problem. Check fluid level and condition. Replace if brown and while the pan is off to clean the filter have the bands and clutch pack adjusted.

go to an auto spares shop and read the oil spec catalogue for your vehicle. Go to a fuel depot and ask them for the recommended oil specs. Read a owners hand book or go on line and type in recommended oil for merc diff c200K. Generally if it is an ordinary diff the an OEP 80/90 oil be ok and if it is a LSD diff then an OEP LSD oil will be ok. I am suspicious of a dealer that will not say what can be found out as general knowledge as they may be using any old oil but loading up the price claiming to be a special merc oil. I have found in business that to be helpful to people generally creates the opportunity to foster a business relationship and after all that is how I keep repeat customers.
