Petrol against the other Alfa Romeo 147 versions

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 147 specifically, petrol is the strongest at 64.6%, and this petrol version sits 2.2 points above the 62.4% model average.

What it means if you are buying one

The petrol Alfa Romeo 147 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 Alfa Romeo 147 had covered 87,565 miles at test, against 114,160 for the diesel. That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures.

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 147 page separate age from fuel if you want to isolate one.
