Wink Haynes Manual

Hey Kdubbu,
Changing the oil is pretty simple, as well as other procedures. Get the Haynes Manual 123 Diesel. lots of good stuff. It may help you understand some of these posts! GOOD LUCK! CD in SC

motor flush

ANyone ever use Motor Flush or anything similar to flush the oil system before changing oil? Is this taboo or just a waste of money?

You might also want to search the archives for sucking out the engine oil. TXBill's web site recommends the drain plug method, but many of us (including most MB dealers) use the vacuum method, sucking the old oil out the dip-stick tube. A search for "topsider" will give you more information than you can read in a week.

The Chevron Delo and Shell Rotella that Bill mentioned can be found at any Walmart. What really makes it convienent is they are both sold in 1 gallon jugs. The Chevron oil is easy to spot, the containers are blue. The Shell Rotella are white with Shell's logo on it. Personally I use the Chevron Delo 400.

The instructions on the referenced website are very good. The only differences that I do are:

Step 7.
While lowering the cover onto the canister I make sure the large O-ring stays in the groove by feeling for it with my finger tips just as the cover is lowered to meet the canister housing. I had one incidence where the O-ring fell out and was clipped into two parts (front and back) while I tightened down the cover. I did not check that area for leaks before driving off. Fortunately, I needed diesel and stopped only a few blocks away to fuel up where I had planned to check the oil level. I had lost almost all of my oil in those few blocks with a massive leak around the canister cover. Needless to say I ALWAYS check that O-ring area for leaks now immediately after starting the engine.

Step 12.
I check the oil level again now when the car is on level ground.

But that’s just me. The instructions are excellent as they are. I’d just say that for the most part you can’t go wrong with a quality 15W –40 diesel rated oil such as the ones mentioned – Chevron Delo 400, Shell Rotella, Mobil Delvac…… If you want to learn everything about oil, go to this website and do some searches:

oil change

I talked to a guy that worked for garret turbines, and he said that their turbine engines for planes take special oil, but if you are in a remote location he said through their testing they have found that shell rotella T 15W40 is the best for their turbines.

I started using it in my 83 300CD, and the oil pressure increased over using the delo 15W40.

I looked over the link shown about changing the oil, and the orings on the shaft connected to the oil can top, well my orings almost look like metal, they seem very very hard. Are they supposed to be rubber? Everytime I change the oil, I have looked at them and wondered. Can anyone tell me where to get new ones? They dont come with the heingst filters I ususally get. How can I get the rings off too without damaging the shaft?

My car has 465k miles, should I start changing the oil more frequently, what would be a good time to change the oil?

Thanks,

Austin

Mercedes Benz regularly publishes a list of recommended oils for MBs. Their latest list is here:

The two little o-rings on the cover stem serve to isolate the pressurized oil being fed to the bearings and the rest of the engine for cooling and lubrication from the bypass flow at low pressure being returned to the oil pan. If the o-rings get too old and cannot hold pressure, the pressurized oil short circuits to the pan, and you lose actual pressure to the bearings. Also, when you shut down the engine, the oil filter housing is supposed to stay full of oil, so that when you start up there is a minimum period of time before the oil system is up to pressure and the flow to the bearings is established. These o-rings prevent the draining of the oil filter housing. If the oil drains, then the engine runs without pressurized oil feeding the bearings until the housing fills up again. Another potential for damaging the engine. So they should be replaced on a regular basis, but how often is up for grabs. For the newer Diesels like my !998 the two o-rings are supplied as part of the kit with the filter, so you change them every time. Maybe that is a hint. Jim
