how many liters oil it's for a CLK 2003 ,engine 2597 cc

there should be a sticker under the hood somewhere if not the parts store would have the info on the computer so they will be able to tell you when you pick up the oil for the oil change,, if you want the info now just google it

If you change the filter, and you should, you will need an additional quart for the filter.

its already included/factored into the amount it tells ya,, whether you get the info from a chiltons or the parts store computer the car manual or the sticker under the hood,, changing the filter isn't something ya should do its something you just do, do so when something tells ya how much oil a car takes its already accounting for the filter,,, and this is what ive consistently found online for the capacity 2003 CLK 500 Synthetic 5w30 8.5L filter and oil coolers or whatever would already be factored in this is the link where I found that info lists all sorts of years and modlels of the CLK line,, along with tons of other specs and info so I would bookmark it ,, anyways heres the link http://cararac.com/engine_oil/mercedes-benz/clk.html

All the Mercedes I had for over 45 years took 8.5 quarts of oil.I now have CLK Cabriolet which still takes 8,5 quarts.

I am getting a oil smell inside car after having oil change.
