Why the fuel type changes the number
Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.
On the Mercedes-Benz C specifically, hybrid is the strongest at 87.6%, and this petrol version sits 1.2 points above the 78% model average.
What it means if you are buying one
The petrol Mercedes-Benz C 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 petrol Mercedes-Benz C had covered 76,080 miles at test, against 95,767 for the diesel and 66,318 for the hybrid. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.
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 Mercedes-Benz C page separate age from fuel if you want to isolate one.
