Petrol against the other BMW 730 versions
| Fuel | Pass rate | Tests |

| Petrol | 79.1% | 340 |
| All BMW 730 | 85.4% | 9,330 |
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 BMW 730 specifically, diesel is the strongest at 85.6%, and this petrol version sits 6.3 points below the 85.4% model average.
What it means if you are buying one
The petrol BMW 730 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. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol BMW 730 had covered 123,593 miles at test, against 104,518 for the diesel. That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself.
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 BMW 730 page separate age from fuel if you want to isolate one.
