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 Jeep Grand Cherokee specifically, petrol is the strongest at 85.3%, and this petrol version sits 2.3 points above the 83% model average.

What it means if you are buying one

The petrol Jeep Grand Cherokee 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. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average petrol Jeep Grand Cherokee had covered 63,121 miles at test, against 76,580 for the diesel. That is around average, so condition and service history will tell you more than the odometer does.

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 Jeep Grand Cherokee page separate age from fuel if you want to isolate one.
