DIY Oil Change on 2006 - 2007 C230

The eninge on the 2006 - 2007 C230s is a bit different than the earlier models . . . So I thought I would post a DIY thread for changing the oil; which I did today

1) Warm the engine a bit so the oil will flow more readily.


2) With the front portion of the engine cover removed, the oil filter is located on the front of the engine, slightly to the driver's side.





3) I could not locate the drain plug, probably under the splash panels. So, I pumped the oil out (2006 model has a dipstick)





4) I replaced new filter and 3 O-rings and re-install the filter. I noticed that there is a paint mark on the filter cap, so you can use that to tighten it the same amount.





5) I filled the oil with with 8 qts (+/-) Mobil 1 0W-40. Turned ignition to on (but not start) for 10-15 seconds before starting engine (I believe there is an electric pump that will prime the new filter). Then, I started it and ran for a while to make sure everything was OK.



6) Now to Re-set the maintenance indicator . . .
-- Ignition to on (but not start)
-- Page dash display to odometer
-- Arrow down to Service Indicator
-- Press Reset Botton (left side of instrumentcluster) 6 seconds until is asks to reset
-- Press again for 3 seconds to reset.
-- The next maintenance interval should display (13000 miles)

That's it, piece of cake.

Great DIY!! I need to do this soon too. Got a question though... what pump did you use to take oil out? Are you sure there's no drain plug?

every vehicle on the road has a drain plug for draining oil. on the newer benz's with the 272/273 engine the drain plug is located on the lower oil pan (black pan). have to remove the underbody panels to get to it.

First, thanks for the detailed DIY post, don't think I would of tackled the job myself w/ out it.

Did the oil change yesterday... I now know the real beauty of my Benz is under the plastic covers of the engine compartment and under the car.


Used a STP filter, only one Autozone had in stock, but looked better quality then stock (guranteed to exceed stock blah blah blah). I came w/ the three o-rings for the filter housing and also two more, both smaller than the the two oil filter o-rings. Used one for my dip stick, saved the other just in case someone knows what it's for.

I did it the old fashion way, drained from the bottom. Bought a set of Rhino Ramps (great investment for $45) and drove up on them to raise the front of the car. Had to remove first the front plastic cover and then the mid section cover from the bottom. Easy, thin plastic w/ 8 hand tight screws holding them in. Then drained the oil, plug on the side of the oil pan ( plug was located on a small dropped down area to get every drop out. Warning... plug located on the side and comes out real fast. I then took a floor jack positioned under the diferential and jacked till level to get every drop of oil out.

Filled w/ 8 quarts, ran , and checked, then put all covers on and lowered vehicle. Checked when lowered, level was low, added half a quart, still low, added the rest and just about perfect. Level was to the "a" on max which may be about a 1/8 of a quart high.

Anyways draining from the bottom gets every drop out, and if pumping from top leaves a quart in..... then I'll be crawing underneath every time.

Thanks OP for the pics. I just did it this weekend using your instructions.

A couple of things to add:

1) There are two plastic panels you have to remove underneath the car to get to the drain plug. The panel closest to the front of the car has 6 screws you need to take out. I used a 5/16" socket.

The second panel has 4 screws to take out, also 5/16"

2) The drain plug is 1/2" and is located on the side of the black pan as others have mentioned. Watch out for the crush washer falling into your oil drain pan. I didn't realize it until I drained my dirty oil

3) It'll take 9 qts to fill up the oil.

In summary:

Tools you'll need:

5/16" socket
1/2" socket
oil filter
9qts of Mobil 1 0-40

That's all! Easy job and you'll save yourself a ton over going to the dealership.

Great pictures. You are right, it's very different on the pre-2005 cars. Back then MB included free maintenance, just bring it in, they give you a loaner, you get your car back in a few hours with new oil. But your way sounds like it's more fun.
