Misfuel risk Moderate

UK G70 is petrol only — diesel in petrol is the main forecourt error.

If the engine was not started

Do not start the engine or cycle the ignition to RUN (diesel pre-heat). Have the vehicle recovered if needed and fuel extracted from the tank before any crank attempt.

If the engine was started

If the engine ran, spark plugs, injectors, catalytic converter, and filters may need replacement after draining and flushing per OEM limits.

Access procedure

  1. Switch off ignition, apply parking brake, and disconnect the 12 V battery negative terminal where OEM procedure requires.
  2. Relieve fuel system pressure per workshop manual (fuse pull or diagnostic command).
  3. Access the fuel pump module via the approved panel or by lowering the tank as specified.
  4. Extract contaminated fuel with an approved extraction unit; label waste for hazardous waste consignment.
  5. Replace fuel filter(s) and inspect lines; flush if OEM specifies after misfuel.
  6. Refit components, reconnect battery, and prime the fuel system before a short road test.
  7. Record tank capacity drained and disposal paperwork for duty-of-care compliance.

Frequently asked questions

What if I put diesel in my petrol Genesis G70?

Do not start the engine. Diesel in a petrol tank will not ignite easily but can foul spark plugs and the fuel system. extract fuel from the tank per OEM procedure and replace filters as specified.

Will misfuel damage void my Genesis warranty in the UK?

Genesis warranty terms typically exclude damage from incorrect fuel or contaminated fuel. Keep invoices from an authorised repairer or GBIFDA-certified operator; disputes may be referred to the Motor Ombudsman or Trading Standards.

Where is the fuel pump access on a Genesis G70?

On most UK-market examples, access is via a service panel under the rear seat or in the load area — confirm in Genesis workshop manuals for your chassis code. Saddle-tank designs may need both sides drained.
