I seem to be having trouble finding information related to changing the oil on my slk 230. I couldn't find anything more than what type to run (mobil 1 syn). What weight is recommended? Also, can I buy the "special" wrench for the filter online? I'm still looking for a chiltons manual or similar to help me w/ some of the basics.

I'm not new to cars, just mercedes. Thanks for any help, and nice site!
