Petrol against the other Mazda 6 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 74.3% | 32,906 |
| Petrol | 75% | 28,464 |
| All Mazda 6 | 74.6% | 61,393 |
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 Mazda 6 specifically, petrol is the strongest at 75%, and this petrol version sits 0.4 points above the 74.6% model average.
What it means if you are buying one
There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol Mazda 6 had covered 83,746 miles at test, against 101,636 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 Mazda 6 page separate age from fuel if you want to isolate one.
