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 Ford Mondeo specifically, hybrid is the strongest at 88.5%, and this diesel version sits 0.2 points above the 72.7% 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 Ford Mondeo had covered 121,151 miles at test, against 98,064 for the petrol and 71,376 for the hybrid and 120,151 for the electric. 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 Ford Mondeo page separate age from fuel if you want to isolate one.
