Petrol against the other Subaru Legacy versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 70.3% | 4,363 |
| Diesel | 64.1% | 761 |
| All Subaru Legacy | 69.4% | 5,139 |
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 Subaru Legacy specifically, petrol is the strongest at 70.3%, and this petrol version sits 0.9 points above the 69.4% 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 Subaru Legacy had covered 112,035 miles at test, against 114,746 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 Subaru Legacy page separate age from fuel if you want to isolate one.
