Petrol against the other Lexus Is versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Hybrid | 90.3% | 12,551 |
| Petrol | 87.2% | 509 |
| All Lexus Is | 90.1% | 13,098 |
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 Lexus Is specifically, hybrid is the strongest at 90.3%, and this petrol version sits 2.9 points below the 90.1% model average.
What it means if you are buying one
The petrol Lexus Is 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. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol Lexus Is had covered 67,106 miles at test, against 77,930 for the hybrid. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.
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 Lexus Is page separate age from fuel if you want to isolate one.
