Petrol against the other Chevrolet Trax 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 Chevrolet Trax specifically, petrol is the strongest at 70.4%, and this petrol version sits 2.6 points above the 67.8% model average.

What it means if you are buying one

The petrol Chevrolet Trax 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 Chevrolet Trax had covered 72,845 miles at test, against 91,123 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 Chevrolet Trax page separate age from fuel if you want to isolate one.
