After all the info. I got from your nice people about which oil do I use so, I called around the benz shop and to my supprised none allow me to bring in my motor oil (they all use other than mobil 1) So, what do I do?! Should I bring it into the dealer? But, they are all book till Nov!!! and for a oil change is $70...(it only cost $40 in South Carolina) Maybe I 'll just bring it to Jiffy lube and
