⚠️ Mazda Mazda2 — Low misfuel risk
NZ Mazda2 is petrol-only in recent years — diesel in petrol is uncommon but harmful if cranked.
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 tank drained 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.
⚠️ Mazda position — Mazda2
Mazda New Zealand warranty excludes improper fuel. Use Mazda Workshop Manual / M-MDS diagnostics for SKYACTIV systems and approved drain sequences.

Frequently asked questions
What if I put diesel in my petrol Mazda Mazda2?
Do not start the engine. Diesel in a petrol tank will not ignite easily but can foul spark plugs and the fuel system. Drain the tank per OEM procedure and replace filters as specified.
Will misfuel damage void my Mazda warranty in New Zealand?
Mazda warranty terms typically exclude damage from incorrect fuel or contaminated fuel. Keep invoices from an authorised repairer or NZIFDA-certified operator; disputes may be referred to the Motor Vehicle Disputes Tribunal or Commerce Commission (Fair Trading Act 1986).
Where is the fuel pump access on a Mazda Mazda2?
On most NZ-market examples, access is via a service panel under the rear seat or in the load area — confirm in Mazda workshop manuals for your chassis code. Saddle-tank designs may need both sides drained.
