Changing my Oil with a Extractor pump!
Hey guys i have a Mityvac extractor pump and the oil change is due in about 2k miles. Going to replace the oil with

and use the pump. I am curious, since i will be doing it through the dip stick, as it is called by the service manual to be done like that, does anyone have any anti friction additives i can add to the oil prior to doing this?
Regards,
Mario

I've been using a Mityvac for about 15 years. Very good product that gets the job done quickly and with relative ease. One thing I've learned the hard way is don't store the oil in the pump for more than 36 hours. The membrane of the pump get saturated with oil and then comes out the handle next time you use it. It's a mess.

I'm a little skeptical about using suction to remove your oil, I prefer the old fashion way of letting the oil drain out of the pan. Because with suction, do not get all the oil out.
Granted, one can never get 100% of the oil out, it's impossible. But with draining both the oil pan and oil cooler, I can feasibly removed 98% of it. But that is my opinion, and my way of doing it.
I'm not saying that your way is wrong, we just have different ways of accomplishing this task.

No. Just the MB spec 229.5 oil. I've used MB and Mobil but any with the specs 229.5 should be fine. I used Castrol in a BMW Z3 for over 10 years and liked the result very much. I may switch to it if I can find it.
About 50 years ago, I used various additives but I believe they are like snake oil of old. Good marketing but doesn't actually do anything positive for the car. I suppose if you have a particular situation it might be wise but otherwise use what the manufacturer recommends.
Good luck

Those of you who think draining will get more oil out than suctioning, try the following experiment.
Suction your warm oil then crawl under the car and remove your plug to see how much additional oil you drain out. The amount will be : ZERO.
Your suction unit (in my case a MityVac) should attach to the top of the dipstick tube, which reaches to the lowest point in your oil pan, in many cases actually lower than the drain plug. Some insert a plastic tube through the dipstick tube but that is counterproductive and only slows the extraction.
This is the way I have done it on all my Benzos and is the way your dealer does it also.

Rocky Raccoon, I agree with using the suction method and would like someone to test your point.
However, two things to consider. I just removed my upper and lower oil pans in a 07 CLS550. It has the oil pickup tube and lower oil pan in the rear.
1. I removed the lower oil pan without removing the dipstick tube yet. I witnessed (total bummer that I didn’t take a picture) that the tube does not extend below the drain plug which is in the side of the lower pan. Exactly how far they are a part I do not know. I could have easily measured if I knew this was a point of debate.
2. People that insert tubes into the dipstick tube can absolutely get to the lowest point of the lower oil pan but it creates other drama as stated.
With that said. It sure would be awesome if someone with a vacuum would do that and then open the drain plug and measure what comes out. I don’t expect it to be much but it won’t be zero in my car.
i also wouldn’t say to do one method over the other because the dealer does the vacuum method. They are into speed and could care less if one leaves a bit more than the other. Research the posts about trans flushes and them not draining the converter.

I have conducted the experiment as described with the described result. Full disclosure is that I did it on my 1983 300CD. I have not done it on my wife's 2008 E320 since she still takes it to the dealer for service. I have verified with them that they use the suction method.
There will always be a little old oil left in the engine hoses and galleries. My diesel OM617 engine holds almost 8 quarts and my wife's diesel about the same as do most Benz engines. A few ounces of old oil hurts nothing.
Attaching to the upper end of the dipstick tube is done at the dealer with a special fixture. There are myriad ways of doing it at home using tubing and hose clamps or drilled rubber corks. I adapted a hardware item. The MityVac includes a drilled cork-like fixture.

This obsession with getting all of the old oil out during an oil change reminds me of a trick my father always did when he changed oil. Once all the oil had drained out, he would start the car. It would run for only couple seconds and then he would turn it off. Sure enough a little more oil would drain out. Never seemed to harm the car but the small amount of additional oil left didn't seem to hurt it either. I must admit that back when I rode motorcycles I tried it a few time. Since the oil capacity was much less that a car, getting more old oil out seemed more useful. However, turning the motor over only yield a couple ounces so I stop doing it there too.
