I have just purchased a 2005 CLK320 which is my first Mercedes. For obvious reasons, I want to be sure to give it the care it deserves and will be asking other owners for advice. I just hope I don't become a PITA.

Some of the questions I have regard the best oil to use in the CLK320, as well as the best finish products to use. I've heard a lot about Zaino Bros. products but know little about them except from the hype on their own website. Anyone here have experience with Zaino Bros.?

 

We're all a PITA. Join the club.

If money is no issue, use synthetic oil. It's all it's cracked up to be. Most importantly, no sludge. Longer period between changes for normal driving.

I use Zaino Bros stuff. It's the best stuff I've ever used. Easiest to use as well. You're treading on goofy ground with your question, though. The debate over the best car care products is like arguing over who's baby is the cutest.
