Petrol against the other Vauxhall Insignia 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 Vauxhall Insignia specifically, petrol is the strongest at 77.7%, and this petrol version sits 3.8 points above the 73.9% model average.

What it means if you are buying one

The petrol Vauxhall Insignia 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 Vauxhall Insignia had covered 75,352 miles at test, against 106,398 for the diesel. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.

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