Petrol against the other SEAT Leon 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 SEAT Leon specifically, petrol is the strongest at 82.4%, and this petrol version sits 2.5 points above the 79.9% model average.

What it means if you are buying one

The petrol SEAT Leon 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 SEAT Leon had covered 64,810 miles at test, against 104,336 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 SEAT Leon page separate age from fuel if you want to isolate one.
