Petrol against the other MG 6 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 MG 6 specifically, diesel is the strongest at 69.7%, and this petrol version sits 1.6 points below the 67.7% model average.

What it means if you are buying one

The petrol MG 6 fails more often than the model average, so budget for the items that catch this fuel type and treat a fresh MOT as worth paying for. 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 MG 6 had covered 72,318 miles at test, against 70,976 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 MG 6 page separate age from fuel if you want to isolate one.
