| Fuel | Pass rate | Tests |

| All MG Zt | 71.1% | 1,414 |
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 Zt specifically, petrol is the strongest at 73.3%, and this petrol version sits 2.2 points above the 71.1% model average.
What it means if you are buying one
The petrol MG Zt 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. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol MG Zt had covered 86,603 miles at test, against 125,547 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 MG Zt page separate age from fuel if you want to isolate one.
