If you have a Mercedes oil question, read this FAQ

If the dealer uses a sucker to drain the oil why can't they do the same with the 5 speed lifetime transmission that never needs a fluid change. BS.
On the AMG I always have dealer change the oil for warranty considerations, there is an MB brand filter, and to show a service trail. My dealer charges me for the crush washer and new screw. Too cheap to invest in a sucker? They try to charge extra for the zero oil because "the AmG takes more oil than the regular M113 engine."


Many dealers will try to charge you extra for the 0-40 oil. They stock 5-40 oil because
it is cheaper to them in bulk, lumpenproleteriat don't believe zero viscosity is good
, you make up a reason.

It will get the majority out, especially if you extract and then let the valve body drip and then re-extract. All that will be left is a thin layer that you can remove from the pan with a towel. I always drain the 722.6 tranny with the extractor. If the filter is old, I then drop the nearly-empty pan and replace the filter. Otherwise, I just refill the oil - easy enough.

The problem is, only dealers have access to this special oil in the U.S. and they are not sold to the public in individual quart sizes (to my knowledge). The dealers buy them up in big drums. I am unsure if dealers carry individual quart bottles - will have to check.
So this leaves a problem for those DIY oil changers. The solution is to simply use Mobil 1 0w-40 oil. It also complies with 229.5 spec and is perfectly fine for use in modern benz gasoline engines (such as the M272 in my 2009 w204). The main difference is that the 0w-40 is good in colder climates, and the 5w-40 is better in warmer climates, in my experience.
ESP = emissions system protection and is NOT an additive. Rather it's lack of ash content. This is 229.51
The 5W-40 oil dealers are putting in ALL engines is the 229.51 oil--dealers have pneumatic-powered automatic oil dispensers that can accomodate one grade only. There's no "selector." 229.51 does not hurt gas engines. 229.5 indeed hurts diesel particulate filters.

The Best of Mercedes & AMG
I have a few different older MB's and have used Mobil 1 20W-50 in all including an air cooled Porsce. While the oils I use may or may not be recommended all vehicle are 21 to 15 or so years old and still run great.
My question is what if any substaintial difference is there between. 0w-20 and 0W-40. I have a new 4runner with 4L six cylinder with a manual that recommends 0W-20, but says "An oil with a higher viscosity (one with a higher value) may be better suited if the vehicle is operated at high speeds, or under extreme load conditons.
Would the Mobil 1 version of 0W-40 be of higher quality than their 0w-20?
I've taken a little bit of a bashing on BITOG webforum for having the audacity to not blindly us 0W-20. I am of course no expert on oil, but have many years experience working on cars. When I've drained oil with these thin synthtic oils it comes out like water. I can only imagine how thin the 0w-20 will be. It just seem that living in a hot humid environment where it get to be over 100 degrees F and rarely below freezing that a 0w-20 would be uncalled for. Maybe has something to do with mileage and marketing.
In fact the Austrialian overs manual for this engine recommends other oil weights.

BTW, the ONLY reason i am using the services at the dealer is to "renew" the benefits of the "free" roadside assistance. I was told that if you are not the original owner of your benz, you need to service your car at the dealership (minimum of $100) to continue receiving benefits at no charge.
help please benz enthusiasts!!

A: Check your manual.
The following applies to FSS cars: If your car is 1998 or newer, it should have Flexible Service System (FSS). This means the car will alert you (on the gauge cluster) when it needs the oil changed (generally every 10k miles or 1 year, but this varies). Oil needs to be changed generally because either the filter is full of particulates, there is too much particulate in the oil that is too small to be filtered, or the oil/additive package has degraded.
Best advice is to change at 10k or earlier depending on your local conditions, i.e. heat, dust, how you work the engine, etc. I would agree that 3k/3 months no longer applies and 5k/6 mo is not necessary for most people. But 10k/12 months is the outer limit. Of course the BMW module sometimes exceeds even this benchpost




Simple MB engines can run on ANY oil in the store, given the proper climate and change interval.
I go as far as to say 2 changes of "dino" oil will work better than 1 change of "synth" oil over the same period. That is, 6 months instead of a year or 5000 miles instead of 10,000. Slightly better chemistry of synth oil is no substiture for physically draining out contaminates and putting new oil in that has fresh friction modifiers. Extended drains are for new or difficult to service exotics. If you can and do change your own oil at 5000 miles, wth would you spend double on the oil to do the exact same job? I think young guys with only one car have a different perspective than someone with a lot of cars doing this service over decades. I've used 100s of jugs of oil. No way would I spend $45 a pop for LLubro Moly or Motul or whatever just for bragging rights.
Most any 10w-40, especially HM oils like MaxLife or Pennzoil or Mobil Clean are much better than even the synth oils from when these engines were built.
How about a premium HDEO 10w-30? https://www.texacodelo.com/en-eu/pro...XLE10W-30.html Does anyone really think an oil this good is going to harm an ancient V6? If someone says yes, it's out of ignorance.
I will stop back here and complete my post later.
