Do not start the engine — this is the most important step
If you realise before starting the engine, the contamination is contained to the fuel tank and is straightforward to fix. Starting the engine circulates the wrong fuel through the fuel pump, injectors, and fuel lines — damage that can run to $5,000 or more in a modern diesel.
What No Fuel Station in NZ Can Do for You
What they can do: Ask you to move the vehicle away from the pumps, call for assistance on your behalf, and advise you not to start the engine. Some stations have forecourt staff who are trained in basic emergency response. None of them can fix the problem.
What to Do at the Fuel Station Right Now
- 1Stop fuelling immediately
Remove the nozzle and replace the fuel cap.
- 2Do NOT start the engine
Not even to move the car. Stay where you are or push to a safe spot.
- 3Tell the station attendant
They can block off the pump and may help move other vehicles. Ask them to note the time and what fuel went in — this helps your insurance claim.

Why You Still Need a Specialist — GBIFDA Certification
Under UK law, contaminated fuel is a hazardous substance. You as the vehicle owner are legally responsible for ensuring it is handled by a properly licensed operator. Using an unlicensed operator can void your insurance, expose you to environmental liability, and leave you with no legal recourse if the work is done incorrectly.
The GBIFDA (Great Britain Insoluble Fuel Disposal Agency) is the certifying body for misfuel recovery operators in NZ. Certified operators must have:
Eek Mechanical is GBIFDA certified. Every job includes complete documentation — the insurer-ready report your claims assessor needs.
Will Your Insurance Cover This?
AMI, State, and FMG comprehensive policies cover wrong fuel removal and repair costs. AA Insurance and Vero do not cover fuel contamination. Whatever your insurer, Eek provides the certified report and invoice your claims assessor needs.
