This website, and another Mercedes site I checked, clearly shows a preference for the topsider method.

I've never used a topsider before, but with all of the posts from concerned owners, I think I'll give it a try. I used to always change my own oil...that way I always knew what was going in...and the quality of the filter installed. I haven't had the time lately, but I think that I will find the time in the immediate future. I'm not paying $80 for a change I can do myself on a car that I love.
