Mobil 1 R is a great oil!
I have been using it in my Honda S2000, my Honda Snowblower, My Garden Tractor, My power washer, My Honda Mantis, and my Ford Ranger Pickup.
The additive package of ZDDP are for extreme pressure conditions that are present in every engine.. On the main journals of the crank shaft. The connecting rod journal. The wrist pins, The Valve Train, Even the tappets.
I would be using it in my MB 230 Kompressor, but it is not a 0W-40. So I use the Mobil 1 0W-40W and add a pint of Valvoline Synpower to up the ZDDP additives.
