⚠️ Mitsubishi manufacturer position

Mitsubishi typically requires tank lowering or chassis access for full drain on SUV ladder-frame variants. Mis-fuel classified as misuse — not warranty.

Misfuel risk High

Diesel variants use common-rail injection at very high pressure; petrol in diesel destroys pump lubrication and can contaminate the entire fuel circuit within seconds of running.

If the engine was not started

Full drain, filter replacement, prime diesel circuit, leak test before start.

If the engine was started

Expect HP pump, rail, injector, and line inspection; contamination debris can be costly on 4N15 common-rail.

Access procedure

  1. Disconnect the negative battery terminal and relieve fuel system pressure per OEM procedure.
  2. Access the in-tank fuel pump module via the manufacturer-specified route (access panel or tank lowering).
  3. Drain contaminated fuel using approved recovery equipment into suitable containers for hazardous waste duty of care.
  4. Inspect the tank, sender unit, and lines; replace the fuel filter and any contaminated flexible lines as required.
  5. Reassemble, refill with the correct fuel grade, prime the low-pressure circuit, and check for leaks before start.
  6. If the engine was run on wrong fuel, follow OEM guidance for high-pressure pump, rail, and injector inspection before restart.

Frequently asked questions

What should I do if I put petrol in my Mitsubishi Pajero Sport diesel?

Do not start the engine or turn the ignition on. Have the fuel extracted from the tank using OEM-prescribed access methods and dispose of contaminated fuel under your duty of care (Environmental Protection Act 1990). Use a GBIFDA-certified technician where possible.

Will Mitsubishi warranty cover misfuel damage on a Pajero Sport?

Mitsubishi typically classifies wrong-fuel events as customer misuse, which is excluded from warranty. Repairs are usually funded by the driver, insurer, or breakdown cover subject to policy terms.

Can contaminated fuel be siphoned from a Mitsubishi Pajero Sport?

Most UK-market Mitsubishi models have filler-neck anti-siphon features. OEM service information normally requires pump-module access or tank lowering rather than suction through the filler neck.

Does a Mitsubishi Pajero Sport need new injectors after misfuel?

If the engine was not started, draining, filtering, and line flush may be sufficient. If it was driven on wrong fuel, high-pressure pump and injector inspection or replacement is commonly required per OEM diagnostics.
