⚠️ Mitsubishi Montero Sport / Pajero Sport — Moderate misfuel risk
NZ Montero Sport was petrol-only. Primary risk is diesel added at the pump. Remaining NZ fleet is aging; tank corrosion can complicate drain procedures.
If the engine was not started
Keep ignition off; drain tank before any crank attempt.
If the engine was started
If run on diesel-contaminated petrol, inspect filters, lines, and injectors; catalytic converter damage possible — diagnose per OEM.
⚠️ Mitsubishi position — Montero Sport / Pajero Sport
Mitsubishi body-on-frame SUVs typically require fuel tank strap removal and tank lowering for pump service. Misfuel is warranty-excluded misuse.
