Engine oil
I have a 2011 ml350 bluetec
I recently had the oil changed and I used Mobil1 0w40.
However the oil did not state that it was for diesel engines... It's this okay or will it damage my engine?
Thanks for your help and feedback.
merry Christmas!

I wouldn't use any oil other than oil which carries the MB specification that the particular diesel engine requires. On the 2008 pre-bluetec diesel model the required specification by MB is 229.51 or alternatively 229.52. There may have been other specifications before and the bluetec engine may have a different requirement to the pre-buetec engine. These oils are not exclusively available from the MB agents only but in the past when I've priced this oil in our area, the oil at the agents (CAD $12.18 per litre including tax) was the same price or even slightly lower than elsewhere. You could probably get the oil on the internet for less.

Thanks for the help and feedback so far guys.
Yeah the specification said to use 229.51.
The Mobil 1 I used said it's the recommended brand for Mercedes and other European cars. It's synthetic and it said (229.5) on the back. On the front it didn't have that (for gasoline engines label) that other oils normally have... Hence I thought it could have been used for both.

The MB 229.51 specification oil is designed for recent Mercedes cars fitted with EURO IV and EURO V engines and applies to some Mercedes petrol engines and some Mercedes diesel engines.
Mobil 1 certainly produces an oil which meets the 229.51 specification but I think there are other brands now that also produce oil that meets this specification.

Perhaps you noticed how ink-black the drained oil was? That is normal for diesels, but not normal for gasoline engines.
"Synthetic" is utterly meaningless when it comes to motor oils. Synthetic is not a performance criteria or standard, it is a manufacturing technique. If used right a superior product could result but just because the techniques were used is no assurance of a superior product.
Drilling down deeper 229.51 is a low ash oil, about half the ash of the best commodity diesel motor oil you'll find at Walmart. Ash is bad for DPF and SCR components in your exhaust.
