I changed the oil on my '02 C320 this past weekend. The hardest part was getting the garage from -4 to a reasonable comfortable temp. :-)

The process was very easy if you have ever changed oil on any car before. First, I put it up on the new "Rhino" ramps, slid under and removed the 2 plastic under-carriage pans. It's true that you only need to remove the rear on, but I took them both off and cleaned the dirt, etc. The drain plug is obvoius with it's copper washer gasket. Undo the plug and be prepared for a little clean up on the floor since it's near impossible to guess where the stream will initially go. While that is draining, unscrew the filter housing and remove the old filter assy. Pretty straight forward replacing it. Remove and replace the o-rings push on the new cartridge and screw it back in. I torqued it to 25nm as specified. Put the drain plug back in. Put in 8 qts. Mobil1 0w-40, fire it up and check for leaks. Pans back and you're done.

Having now changed the oil at 4800 miles, I can tell you it certainly could have gone longer. Not that I will though :-) (anal oil changer) The oil that came out was almost as clean looking as the oil that went in. I know that's not necessarily a good measure of "good oil" - just an observation. The wifes Exploder's oil is BLACK at 3500 miles. MB = Clean engine!!!

Thanks Brian. I was talking with someone recently on how easy was it to change the oil on the newer cars. Sounds like the '02 C320 is pretty easy.

Have you checked into pulling the oil out from the top? Use the search feature with the key word: Topsider

Never gave the topsider much thought. I like the idea of draining the oil from it's lowest point. Makes more sense (to me) that doing this has the best chance to get ALL of the oil and crud out from the bottom of the pan.

Brian

Draining via the drain plug is not the lowest point of the engine because of the thread of the drain plug. The topsider way is a great way to easily change the oil without going underneath the car. Especially since you have a new c320, I wouldn't worry about sludge and crud at this point of the engine's lifetime. MB has designed these engines to have their oil changed via suction. How much did you get the OW-40 oil for?

if you use the topsider...you don't have to "warm" the garage .
Let's get ready for another "oil thread".

=====================

Let me tell ya something...
At -2 you NEED to warm lots of things:-) Oil change kit consists of oil, filter, BMF propane heater for the body and good Brandy, Cognac, or other non-freezing spirit for the insides.....

Now you've done it. I have to drill a new hole in the bottom of the pan!!!

With the car on ramps, tilted towards the plug side of the pan, it doesn't get any lower. If you're really anal (I am), flush a half qt of fresh oil through with the plug still off. I won't worry about sludge ever if I continue to get ALL of the old oil out..


I got the oil from Autozone for 4.95/qt

Brian

Autozone seems to be the only place (besides dealers) that carries Mobil 1 0w40. Some Autozones will match prices, so they'll honor the occassional Kragen sale coupon for $3.99/qt Mobil 1.

brian,

Good job! Draining with the plug will get out at LEAST as much as drawing through the dipstick tube on this engine. I have looked at the location of the drain plug and done the oil change just as you did on my C240 which is the same configuration.

Whether one doesn't want to get under the car or not, the main thing is to change it and change it often.

Those that THINK they are actually drawing more oil out with their gadgets than they could get out by pulling the plug are just justifying their method in their minds. In some engine configurations they MIGHT get out a negligible amount more, but in other cases they won't get out as much.

Draining with the plug is my way, keeping ones hands cleaner might be someone elses way, but just change it regardless of method!

Have a great day,
Change oil hot and change oil often.

I understand how to change the oil .. but i just got my C320 and i do not know how to Measure the oil.. it doesnt have the conventional way of measuring oil... like through the stick.. there is a plug i suspected a stick for measureing the oil would be there.. but it wasn't
What do i do and how do i measure my oil?? thank you

8 qts. of Brandy and 6 oz. of oil?
You're messed up man.

read the owners manual, it is done through the dash display and the menu buttons on the steering wheel. Car level, key in postion zero or one, press the upper left button on wheel till oil level message shows and follow directions.

Just so you know, these vehicles are factory-designed to have their oil drained from above. That's the way the dealerships do it (although they use a vacuum extraction device that uses the dipstick like a giant straw). For the truly anal, tests have shown that Topsider oil extraction actually removes more oil than gravity draining (although Larry and others will probably dispute this). It probably isn't enough of a difference to worry about, when you consider the significant amount of old oil which stays in galleries, etc. anyway.

Obviously, you can change oil any way you want, but to me, it's really handy to do it from above, esp. in bad weather (can do it in the garage -- I wouldn't be able to do that using ramps).

The other point that non-Topsider-owners forget is that it's a good deal less messy -- you drain the oil right into the container you use to take it to the recycling center. Heckuva deal if you ask me!

The other point that Topsider owners forget is that part of an oil change is to perform an inspection of the vehicle. I usually check for loose/worn suspension components, fluid leaks, condition of rubber parts, brakes (since I rotate the tires as well), tire pressure and check all fluid levels.

I sacrifice a messy oil change any day if I can catch a potential problem before it becomes an expensive problem.

The Explorer oil is black because it probably has dinosauer oil in it, put in Mobil 1 and it will stay clean also.
