Diesel against the other Vauxhall Frontera versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 69.1% | 369 |
| Petrol | 66.9% | 357 |
| All Vauxhall Frontera | 68.2% | 729 |
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 Vauxhall Frontera specifically, diesel is the strongest at 69.1%, and this diesel version sits 0.9 points above the 68.2% model average.
What it means if you are buying one
There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Vauxhall Frontera had covered 110,370 miles at test, against 96,735 for the petrol. That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself.
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 Vauxhall Frontera page separate age from fuel if you want to isolate one.
