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 Alfa Romeo 159 specifically, petrol is the strongest at 63.2%, and this petrol version sits 2.4 points above the 60.8% model average.
What it means if you are buying one
The petrol Alfa Romeo 159 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 Alfa Romeo 159 had covered 95,823 miles at test, against 127,657 for the diesel. That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust.
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 Alfa Romeo 159 page separate age from fuel if you want to isolate one.
