I have not driven my car (98 E320) for a couple of months. I have been driving my SUV. I have started the car at least two to three times a week. I figured let me check the oil and it looks like a light brown muddy substance. It looks like the oil is a bit frozen. I had the oil changed before I stopped driving the car but now I extremely worried. What could this be. Keep in mind that the weather here in CT has been below freezing for the last three weeks. Any ideas?

Plus when I started the car the it was not for long just to make sure the battery did not die. Maybe on a couple of occasions I let it get real warm to running temp.

DAS E320,
Welcome to Benzforum. Take Lynn's advice and have a Mechanic look at the oil. Don't drive the car with the oil like this. This may be a serious problem. Did the car ever run hot with you? Keep us posted, good luck.

NO the car never ran hot before. I have been trying yto get in touch with a friend of the family that is a Mercedes mech. I want to have him come over and take a look at it. I will keep you posted.

If you started the car, but did not let it warm up completely (i.e., including the oil, which takes 10-15 minutes depending on use), then you actually caused the problem with your oil. Engines produce water as a byproduct of combustion, and a small amount makes its way into the oil. If you don't get the oil above 212F, the water never boils off and eventually you have the situation you describe.

You should change the oil immediately, and then drive it normally for a time and check the oil again. If you still see the "muddy" look, and particularly if it looks like chocolate mousse, you are likely leaking coolant into the oil, possibly from a blown head gasket. Take it straight to the mechanic in that case.
