Mine dump truck at 42 L per 100 km: is that normal?

25 t dump truck, 3.2 km round trip, 8% grade on the loaded leg.
Fuel is 42 L per 100 km, against about 36 last year.
Drivers say power is unchanged; we want to separate machine from road.

Check intake and intercooler first; a clogged filter is not felt in power but shows in fuel.

Has the road been regraded? Compaction changes rolling resistance; we have seen this.

Measure injector return flow; over-limit injectors over-fuel. Test individually first, replacing four is costly.
