Accidentally Put Small Amount of PEtrol in Diesel Car Suffolk
Diesel engines and petrol engines work differently. Diesel fuel lubricates the engine’s fuel system, while petrol acts as a solvent and can damage diesel engine components. When petrol enters a diesel engine, it can:
Reduce lubrication, causing metal parts to grind and wear
Damage fuel pumps and injectors
Lead to engine misfires or failure to start
Cause costly repairs if the engine runs with petrol inside
Even a small amount of petrol in a diesel tank can cause problems, so acting quickly is essential.
Immediate Steps to Take After Misfuelling
If you realise you have put petrol in your diesel car, follow these steps right away:
Do not start the engine
Starting the engine circulates petrol through the fuel system, increasing damage risk.
Turn off the ignition
If the engine is running, switch it off immediately to prevent petrol from spreading.
