Mobil 1 ESP 5W-30, for example, has Mercedes Approval 229.51 & 229.52. Low ash is critical to avoid clogging the particulate filter. There are many others available, just check the container for the approval. The Mobil 1 Full Synthetic 5W-30 is not low ash.

The factory oil filter is about $18 from the dealer, so not very costly to begin with, but if you look at what’s in the box, it’s a Mann HU 711/6z which is about $13 on Amazon. I use one of those 2. Don’t buy cheap oil filters.

The air filter only requires changing every 50,000 miles unless you operate in very dusty conditions. Just get a major brand that cross references to your SUV. I plan on ordering whatever Mann air filter is listed for my GLB at the next service.

Thanks Odd Piggy for your advice. I bought Mobil 1 with an Approval of 229.51 from dealer but I heard that Mercedes-branded oil will have some special chemical that is better for the engine than the other brand and 5W-40 will be better and help the engine will be last longer. Is it true?

If you live in a very hot area, API 40 viscosity will thin a little bit less at high temperatures, but these late model engines (as opposed to 20+ years ago) are designed with much tighter clearances that are fine with API 30 viscosity.
