After reading this I'm just going to take my car to the Benz dealership for its oil change, but I think I might buy a Mobil 1 filter or K&N filter and give it to them to use. I know they cost a bit more but because of all the media inside I feel it will do a better job and let me keep it in there longer. In the owners manual it says that if your storing your car during the winter months to change the oil because of the all the condensation that builds up when it stored, so my question is this, wouldn't it make more sense to change it in the spring and get ALL the crap out and start fresh?
