Sprinter 20,000 mile oil changes

Can a Mercedes Sprinter diesel engine go 20,000 miles between oil changes like the MB manual recommends? I use Mobil 1 ESP oil. Here are the results on my 2016 Winnebago View and the oil analysis from Blackstone labs. My motorhome is driven on mostly highways including a little biodiesel used in Florida.
