Newer diesel trucks are not as efficient (due to emissions systems) as previous generations? Maybe. Probably. Though it depends on the exact year, model, and version. The true potential is better than some think, and the conditions, load, and nearly everything else matters.
Tests must be repeatable and confirmable. The ECM was slightly pessimistic here, and the odometer a little fast with the stock tires.
