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 G-Class specifically, petrol is the strongest at 87%, and this petrol version sits 1.6 points above the 85.4% model average.

What it means if you are buying one

The petrol Mercedes-Benz G-Class 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 G-Class had covered 49,995 miles at test, against 61,935 for the diesel. That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck.

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 G-Class page separate age from fuel if you want to isolate one.
