Petrol against the other Mitsubishi Grandis versions

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 Mitsubishi Grandis specifically, petrol is the strongest at 63.2%, and this petrol version sits 2.7 points above the 60.5% model average.

What it means if you are buying one

The petrol Mitsubishi Grandis 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. 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 Mitsubishi Grandis had covered 114,631 miles at test, against 134,185 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 Mitsubishi Grandis page separate age from fuel if you want to isolate one.
