Petrol against the other MG Zt-T versions
| Fuel | Pass rate | Tests |

| Diesel | 60.9% | 368 |
| All MG Zt-T | 65.6% | 776 |
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-T specifically, petrol is the strongest at 69.6%, and this petrol version sits 4 points above the 65.6% model average.
What it means if you are buying one
The petrol MG Zt-T 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-T had covered 100,513 miles at test, against 144,695 for the diesel. That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust.
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-T page separate age from fuel if you want to isolate one.
