You can use any of their Diesel Oils that fit the DPF spec and grade. As someone that has solely used Nulon 5W30 LL (yellow 30) on my MB from 120K to 270K, I can say it has serviced me well.
As someone that has opened the intake and cleaned it, seen the cam and associated gear; has dropped the sump and seen the internals, I can say it has delivered as promised on the drum. The Yellow 30 LL oil originally had C3-12 spec but that has changed over the years as have the labels and oils specifications. I never saw the need for ultra low saps (C1-C4). I've had to trust Nulon knows their stuff and changes with the times, and by all accounts it's turned out great.
I initially thought all these label changes were **** covering, in that they've got a spec wrong but time has shown that not to be the case. At least Nulon didn't change as often as Penrite had, that was one reason I didn't use Penrite, that and the little extra cost for their oil.
either will do you fine:
Nulon 5W30 Long Life (yellow 30 on the bottle) ACEA C3, mid saps
Nulon 5W30 Low Emissions (orange 30 on the bottle) ACEA C1, low saps
As you've noticed Nulon is cheaper in the 10L drums, better when on sale too.
@ about 260K
