So I went to change the oil in my clk320 and when I opened the oil fill cap there was this white film, meaning there's moisture/water coming from somewhere. The oil doesn't smell like gas, and isn't turning white, and the coolant level hasn't dropped. I noticed there wasn't a rubber gasket on the cap and wasn't sure if it's even supposed to. Any ideas as to what it could be? Am I looking at doing headgaskets soon?

Thanks
Josh

I bet you are getting a little bit of condensation. You could probably take an oil sample and get it tested or just change the oil, run it for a few thousand miles and pull the cap again and see if the same thing happens. do you use synthetic and how long do you run between changes?

I use mobile 1 5-30 and change it every 2000 miles.

I believe 5-30 is what is listed on the oil fill cap. That's what I use for my BMW M as well.
It's your car, you can use whatever you want. However, there is a history of people experiencing severe engine damage after prolonged use of unapproved oils. On the other hand, you could be seeing condensation from short trips where the oil doesn't get above 100C. Below those temps, the water doesn't boil off.

This is a list of the 229.3 approved oils:
76 Pure Synthetic Motor Oil 5W-40
Castrol Syntec 5W-40

You might be even more surprised if you were to read the owners guide that MB included in W 208's. Specifies oils and viscosities.
MANY GRADES AND OILS NOT LISTED ABOVE ARE IN YOUR MB OWNERS GUIDE ON RECOMMENDED OILS

That list is old euro anyway. You want to check the publicized date for being outdated.

Your advice sounds reasonable on its face, but I wouldn’t recommend the maintenance manual (which you referred to as the owner’s guide) or the "Approved Service Products sheet" that "MB included in W 208's" as you say. You see, the newest W208 is eight years old. So are the docs that were originally included with the cars. I find it more reasonable to use the newest, updated list as supplied directly from Mercedes-Benz. BTW, that list I posted is from Mercedes-Benz USA, and I downloaded it this year. :D

Just so you don’t feel I dismissed your advice without giving it consideration, I happen to have both a digital copy and a hard copy of the original maintenance manual that Mercedes-Benz supplied with my car. Following your recommendation would lead me to page 6 of the maintenance manual where under the “Recommended Synthetic Motor Oil” one of the oils is “Mobil 1 Tri-Synthetic Formula 0W-40”. I’ve attached a JPEG of the page. Wasn’t Mobil 1 Tri-Synthetic Formula discontinued years ago? Go to the Mobil1 website and do a search. You'll see it's not listed. That’s another reason to use the list that I posted – it’s current.

You can get alot more useage from your oil than 2000 miles especially modern synthetics. I don't have a link to the article but there is research out there that suggest that dirtier oil has more lubricating properties than new/clean oil. don't shoot the messenger but oil doesn't break down, it just gets dirty and the microscopic particles that contaminate oil don't cause engine ware. as the article that Marcus's link suggests, the vast majority of engine ware occurs during cold startup.

Thanks for pointing out the backroom, closed door MB policy allowing only those who "slip an envelope of money under the table to an MB exec. guaranteeing; "approved status"

Alot of those blends aren't readily available here in US or Canada.

By the way I do use Castrol Syntec.
IN MY SONS 85 TOYOTA VAN. I'd never use that crap in my CLK let alone an AMG.
We used it in a 1jz, a factory twin turbo motor, IT STARTED SMOKING.
Went to Mobil 1 , fine.
