It probably recommends MB229.51 and MB229.52. It is readily available in Wal Mart: Pennzoil Euro L 5W30 (MB229.51). You can order Mobil1 ESP 5W30 that meets MB 229.51 online or numerous other oils. Mobil1 ESP 0W30 X1 meets MB229.52. If manual states MB229.51 or .52, forget MB229.71.
Maintenance of emission system (GPF) depends on SAPS in oil There is nothing magical about 0W20 grade. However, 0W20 allows MB to achieve better CAFE results. That is it. Only reason why MB wants you to use 0W20 is mpg results and certification by EPA. Personally, I would not touch MB229.71 with 10 foot pole if MB229.51 or .52 is allowed.
I have the same engine in my 2018 E300. It calls for either 229.5 or 229.6 engine oil, no grades specified. 229.51 and .52 are diesel specs, so that probably would be a poorer choice than the old tried and true 229.5 (Mobil1 European Vehicle 0W-40)
229.6 is a 5W-30 spec mainly, though other grades are available, once again probably for the CAFE rating.
For a large car or SUV like these to get 40 MPG (on occasion, not average) is astonishing to me.
A question for the MB tech, MontyPix. What is the bare metal crossover tube that protrudes through the engine cover? I'm assuming some kind of exhaust crossover or waste gate for the turbo. That sucker gets HOT!!
Also, do these engines in fact have a particulate filter, or is low saps just being spec'd to avoid cat poisoning?
