In the US, there is no recommended weight. I think most dealers in the states use pump in either 5W-40 or mabe 0W-40.

In the owner's manual, MB provides a chart with temperature limits for each of the 4 approved multi-visc oils. The two oils with the max hi and low temperature limits in the US are 0W-40 and 0W-30 , based on the last few years.

Do they provide these charts in the Hong Kong owners' manual, to aid the owner in oil selection?

Generally in Hong Kong most cars are either dealer serviced or Indy shop both of which are learned a certain type of oil to use for each manufacture. Plus in the engine bay of our Benz there is a sticker specifically stating Shell Ultra. The manual provides just about the same info as stateside manuals, just most owners leave it to the dealer or shops to pick the correct oil. This is based on the generalization that most Benz owners in HK are not that deeply involved with their cars.

In the states, there is a general tendency for the dealers to supply Mobil1 Formula M 5W-40 oil, that is ONLY sold at Mercedes dealers. Many owners on this board use what is considered the superior Mobil1 0W-40, and they either bring it to the dealer / indy. I've heard of 1 dealer that used an approved 5W-30 Shell Ultra.

In the states, under the hood is a general "Mobil 1" sticker.

So I decided to flip to page 250 just randomly today and came across this. Really relevant right now. I usually wait for a stable idle and go. Didn't know long wait could be damaging.

about 10 seconds, then drive easily until up to temp.

start and go - no intentional delay - of course I have to turn off ECO, set mode to sport and config CarPlay ...

what kind of gas mileage do you get standing still?

If I'm home and the car is ice cold, il go start it and come back inside. I let it idle for a few minutes and when I'm not leaving my house, il let it idle for about a minute and won't let it rev over 2000rpm until its at least 60-70 degrees. Right now with -25 C temperatures and no garage, it's almost a must to let it idle and get some heat going before driving off.

I do let the engine idle for a short while, up to a minute or so, depending on the temperature.
One reason for this is that the tranny is being programmed to hold first gear somewhat too long after a startup from cold.
This is done to speed up the heating of the catalyst.
But I just don’t like to be driving along like auntie Mathilda with high rpm at a low speed.
To avoid this I often do induce an upshift by nudging the gearshift to the right.
But at the very beginning the tranny does refuse this and sticks to first gear.
So the way I do it is:
Get in, start the engine, buckle up, start the sat nav, activate the Bluetooth connection on my cell and then roll off.
Most times I’m able to coast along in idle for a short while.
And then I do take it very easy on the car as I want to to enjoy many, many more years with this great set of wheels.

I wait until the RPM drops on its own to 500-600 RPM then go. This usually takes about 30 seconds. Anymore than this, and you're unnecessarily slowing down the warming up of the engine by not driving which is not ideal. This has been debated in all the MB threads.

At most maybe 30 seconds or so. Once the RPM drops to normal then I am off. By that time the fluids had a change to move a little bit. If it is really cold like -20' like it was a couple days ago I give it like 5 min.
