Petrol Fiat Stilo: MOT pass rate

62.1% of petrol Fiat Stilos pass the MOT first time, measured across 531 DVSA tests on that fuel type alone. Average mileage at test was 87,233.

Petrol against the other Fiat Stilo 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 Fiat Stilo specifically, petrol is the strongest at 62.1%, and this petrol version sits 1.8 points above the 60.3% model average.

What it means if you are buying one

The petrol Fiat Stilo 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 Fiat Stilo had covered 87,233 miles at test, against 111,560 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 Fiat Stilo page separate age from fuel if you want to isolate one.
