How to Change engine oil on a Mercedes Benz C230 Kompressor

This DYI show you how to do an engine oil change on a 2004 MBenz C230 Kompressor. You will need the following ( see FIG1) :
1- 6 quarts of Mobil1 synthetic motor oil
2- OEM oil filter, MANN HU514X
3- oil drain plug gasket, DORMAN 0950101
4- Ratchet
5- 13mm socket - for the oil drain plug
6- 8mm socket - for the bolts holding the plastic cover under the vehicle
7- 27mm low profile socket - for the filter housing cartridge

the first step is to raise the car off the ground so you can slide under it to drain the engine oil. To do this, you can either use a jack and two jackstands or a ramp like a Blitz Rhino Ramp (see FIG2). If you're not planning to do brakes and other maintenance by yourself, then a ramp may be better for you since it gives you more clearance under the car compared to a jack and jackstands of comparable price. If you go with a jack and jackstands and this is your first time jacking up the car, make sure to jack up the car at the jacking points located at both sides of the vehicle. Do not jack up the vehicle at the body panel as this will cause a dent, and of course do not jack up the oil pan or the transmission.
For our oil change, we will be using ramps (see FIG3).

loosen the oil filler cap to remove any pressure in the system(see FIG4).

Step 3:
Slide under the car and remove the 6 bolts holding the plastic cover under the vehicle using the 8mm socket and a ratchet (see FIG5, FIG6 and FIG7).

Now you can see the oil drain plug (see FIG 8). Break that 13mm bolt loose using the 13mm socket and ratchet. Remember the rule : a bolt has to turn counter clockwise To break loose.
Remove the bolt, let the oil drain completely (see FIG 9), then put the bolt back (see FIG 10) and tighten it using the 13mm socket and ratchet. don't forget to use the new copper oil drain plug gasket.
Note: I don't follow any torque specification when tightening that bolt, just make sure it is nice and tight but don't tighten the heck of it

Remove the oil filter housing cartridge using the 27mm low profile socket and ratchet. the filter housing is located on the driver's side behind the engine compartment (see FIG 11, FIG 12, FIG 13, and FIG 14). Slide the filter and the old rubber gaskets off the cartridge and put in the new rubber gaskets and the new filter (see FIG 15). Then, put the filter housing back in its place and tighten it.

put 5.8 quarts of MOBIL1 oil into the engine (see FIG 16) and tighten the oil filler cap.

slide under the car and make sure there is no leak from the oil drain plug, then put the plastic cover back and tighten the 6 bolts.

Step 8:
turn on the engine, drive the car off the ramp into a level surface and check the engine oil level at the dashboad. It should say engine oil level is OK (see FIG 17). You're good to go

Nice first post, very informative. You should also post this on the W203 forum since that's what car you have. Welcome to BW!
