Diesel against the other Toyota Hi Ace versions
| Fuel | Pass rate | Tests |

| All Toyota Hi Ace | 67.4% | 92 |
Why the fuel type changes the number
Diesels carry DPFs, EGR valves and stricter smoke limits, so emissions and exhaust faults account for failures petrol cars never see.
On the Toyota Hi Ace specifically, petrol is the strongest at 73.1%, and this diesel version sits 5.6 points above the 67.4% model average.
What it means if you are buying one
The diesel Toyota Hi Ace is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Toyota Hi Ace had covered 149,317 miles at test, against 125,525 for the petrol. That is very high mileage. Clutches, dual-mass flywheels and head gaskets have usually been through at least one repair by this point, so ask for evidence rather than assume the car is original everywhere.
Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Toyota Hi Ace page separate age from fuel if you want to isolate one.
