Step5:Remove the Oil Filter using the "special mercedes tool" and a 1/2 drive wrench. remove the old filter, clean the encasing and remove the rubber o-rings. Slide in the new filter, and put on the new O-rings provided. (3 in all)
Step6: Get back under the car, Put the Drain Plug bolt back on (don't forget the washer) and wipe the area clean (to check for leaks later)
Step7: Pour in about 5qts of new fully synthetic Mercedes-approved Oil. I used Pennzoil 5w-30, since I live in super-sunny yet not that hot California. You can use whatever you prefer, the last time some people had issues with not using mobil1 or not using 0w-40 etc. If you live on the east coast or where its really cold, you may want to use 0w-40. My car, my choice, same with yours.
Step8: Get back under the car and check for leaks. If everything looks good, put the two plastic pieces back on and drive off the Rhino Ramps. This is very important since you want the car totally level before pouring in more oil to avoid incorrect max readings.
Step9: Pour more oil and keep checking the oil dipstick to make sure you don't go over the max level indicator. I was able to get almost 8.5 qts in... about 8.3 or so I would guess.
Step10: Follow the Service reminder reset procedure and woohoo...you're done!
