I am a new MB owner with the purchase of the GLC300. I am old school and cringe at leaving the original oil in for 10,000 miles. I have always done the first oil change at 1500-2000 miles. For the first oil change I prefer to drain rather than suck it out through the oil filler tube.
My question is how to access the oil drain plug. I just glanced under the car and it appears the entire bottom cover has to be removed and then hopefully I can see the drain plug. I am used to cars having an access panel to enable easy access to the drain plug.
I guess I will find out if I can replace the filter without removing any of the intercooler ducting etc.
I have the filter from the dealer and Mobil 1 0-40W that meets MB 229.5.
First, I don't think you need to change oil at 3000 miles unless you drive in a really dirty environment.. if you really want to change it earlier then 5k or 7.5k is reasonable. Mercs use synthetic high quality oil and I believe a larger amount is stored in the car so the oil gets dirtier slower.
I think you can refer to the w205 forum for knowledge on the oil change. The engine is the same.
The oil filter is easily accessed since it is on the top of the engine(I believe just under the engine decorative cover in the front somewhere). If I were to do this I would probably buy one of those oil suction pumps off Amazon/car part store etc.. and go through the dipstick hole rather than mess with lifting the car and dealing with the oil plug.
Lots of videos on youtube as well. Search on amazon: oil vacuum pump
is it something like this Mityvac 7201 Fluid Evacuator Plus. many different manufactuers.
Not sure which pump is the better one since I haven't done this yet!

I haven't done our GLC yet, but I did our old 2015 C300 and it is basically the same platform. I removed the cover on the bottom to drain the oil. Piece of cake. I do however have a two post lift in my garage. That makes a lot of things easier.
Wow, you have a lift in your garage and live in SoCal? Nice! That would be my dream to have a garage like that. Off the top of your head about how many pop-it clips have to be removed to take off the cover? As soon as my maintenance plan expires I plan on doing my own oil changes.

Honestly I don't remember now but it's no biggy. Don't be afraid to do it. Just keep receipts and your good.
I have been doing oil change for my 2016 GLC for a few times, and have been doing it on my previous VW TDI 7+ years. Instead of trying to access the drain plug, I use an oil pump instead. Link here:

Super convenient, and from my experience it can suck more oil out than letting the gravity doing the work.
I have used this approach for at least 20 years on several MB models. The engines are designed to have the oil pumped thru the dipstick and this same method is used by the dealers. It gets out all you can hope to get.

I still like pulling the bottom cover to inspect other components during maintenance. Everyone to their own preferences.
I have been changing my own oil for over 25 years and last week used the Topsider for the first oil change in my 2019 GLC. Worked very well (and clean).
I vac out the oil too. I use a little electric transfer pump I bought for $20 on Amazon. Total time for oil change including cleaning up and putting everything away is about 15 minutes and everything is accessible from the top of the motor. I will never go back to using a drain plug again.
I regularly do the engine drain of my 2017 GLC 220D
I perform a traditional drain because with the suction, you do not remove everything and the "dirt" that normally does not flow.
for my GLC engine OM 651 I used the oil Mercedes 229.52 with the filter it is 6litres 5W30
new oil specification
MB 229.52 is for high performance oil for engines with diesel particulate filters and extended oil change intervals.
Specifically designed for the latest generation of lBlueTEC diesel engines to

I tended to do this on my motorcycles as well, but at 400. Never purchased a car new, so never have had the need, but if I did, I would do this as well.
The reason? Engine break in. You would be surprised how much tiny pieces and slivers of metal you find in the first change even at 400 miles. Maybe the bikes have less tolerances, so their break-in produces more crap, but then again, I also have a separate rinse bucket when I wash my car as well. These are small slivers of metal and rubber, so I am assuming piston, rings and other excesses. Probably more paranoia than a big difference overall, but I have been more happy knowing that crap is not floating around.
Also note bene - for the 2nd change, those things were not seen.
Personally I prefer to remove the drain plug on a warm engine and let it go till it stops dripping but that`s what I have always done with my vehicles. I usually use the time this requires to do other tasks on the vehicle like rotating the tires. I restored a 1970 Benwil 2 Post Lift that was laying in a field rusting about five years ago and that has made oil changes and vehicle maintenance a pleasure relatively speaking.
I have completed oil changes on my 2018 GLC using a oil suction pump. The oil filter is easy to get to and the entire process takes no more than 20 minutes.

I wonder how does changing oil yourself effects warranty ? If something happens with the engine, can the dealership say 'seems like you never changed oil so the issue is because of that'? and you wouldn't have any proof (no invoice/payment receipt)?
Save your parts receipts and log when you changed it and at what mileage. I buy MB filters. They cannot refuse a warranty claim because you did it yourself. Just keep records of everything. Same goes for having a private shop do the work.

I do all of the A & B services myself. Just buy approved parts, save your receipts, and they can't say a thing. You also don't need to buy "MB" parts as long as they're approved parts. E.g. I wouldn't trust anything but Liqui Moly in my engines. Just make sure whatever oil you use is 229.5 approved.
