After Break In Oil

The change in the diesel oils is based on the mandatory low sulfur diesel fuel now available. Supposed to be cleaner burning and lower soot emissions. Diesels are also evolving to an OBD2 type of engine management control that will allow then to be emission tested like 96 and newer cars, no codes and fully active it will pass, no tailpipe probe. Many already have catalytic converters. As far as oils, as long as you have good film strength to keep metal to metal apart you should be ok. Diesel and synthetics have it, there are additives for regular oil to increase it's strength.
