Oil question
 

I have a 2002 clk 320, and I just opened the oil cap and there is some goopy looking yellow stuff on the cap. Can anyone tell me what it is, and what would cause it? :eek:

It is water, condensed from vapor in the crankcase. Short trips will cause this.

Here's a pic I just took. Is this anything I should be worried about? http://i546.photobucket.com/albums/h...man/oilcap.jpg

Clean it off as much as you can, but yeah, its from condensation. I see this on at least one car per day.

The engine operates better using motor oil, not peanut butter.:D

I had that on my 76 volvo with the v6 renault engine. I found the crankcase breather tube was clogged.

I use synthetic Peanut oil, only the best for my Benz. :D

Right, cars just aren't made for short trips. If you have only a short ways you must go the long way and then circle around a few times. Getting lost for a while is good idea too. This is an absolute must. The only other alternative is to get an older car that isn't a piece of crap.
