If someone were to move to 5w40... would that plug up our DPF and CAT?
I wish I could find a DEF delete for my ML250.

I ma not sure that your MB calls for certain weight. I think it calls fro MB 229.51, and there are various flavors, 5W30, 5W40 or 0W40 in the US.
I used in BMW X5 35d Valvoline 5W40 MST that is MB229.51 approved bcs. I got bunch on sale. But one could not beat performance of Mobil1 ESP Formula 5W30 back than.
