Hi John, My 602 ('91 300D 2.5t) also seems to wait before it pegs - but I checked the Owners Manual and it said the Pressure should be pegged by approx. 3000 RPM. Mine is like yours and pegs at 1600-1800rpm. So, according to MB it doesn;t seem to be a problem.
I had been using 15W50 Mobil 1 but changed to the more Diesel specific Mobil 1 Turbo & Truck 15W40 oil (Walmart has the 5 qt jug for ~$20.) and while I was hesitant to change and lose the added viscosity, but it seems to have been for the best. I don't see any negative aspects after 9000 miles.
