well i got all int info i needed from the shop foreman @dealership
to change the oil on the 06 clk you have to buy the oil filter removal tool $25- and filter 20- then remove the engine panel under the car
there is a oil drain plug on the left side of the pan thats it !!
it takes 7.5 quarts not 8 and if you over fill it thats bad , the car will only tell you if its above or below range the book says 7.9 qt (( yes mobil 1 only))

the dealer changes the oil by sticking thier sucker machine DOWN THE RED DIPSTICK LOOKING PLASTIC CAP AT THE BACK OF THE ENGINE this is how they do it fast !!!!

also this car has 25 COMPUTERS !!!
as far as changing the tranny fluid its only @100 k miles - dont i takes a special machine to PUMP the fluid in the tranny and hey for 250-350$ ill pay for it , apart from that the car is maintence free ,

 

Hello, I am unclear on how I am supposed to get the oil out, if the dealer uses a sucker machine. What do I use, if I don't have the machine? I assume that taking the filter off will not allow me to drain all of the oul out. Thanks

nope the filter housing is black plastic and you must use thier tool to take it off , other wise it will break or crack spend the 25- asd but the oil removal tool ,
there is two ways to change the oil 1 is ger under the car pull of the plastic panells and use a murror and flashlight to locate the oil drain plug ,
second is look at the back of the motor you will see the red cap this is the hoke the dealer puts a 5/1 od tube down and uses some sort of suction device /
to suck all the oil out ive looked around but there is a few but i dont want a hankey - pankey sucker i want a real sucker !!!!
im off to check out the local snap- on catalog + mac tools. ill keep ya posted
