Common mix-ups
Different fuels. The same first move.
Do not start the engine. The sooner contaminated fuel is isolated, the better.
Diesel in petrol
Diesel is heavier and burns differently in a petrol engine. The vehicle may be hard to start, smoke or run poorly if the fuel circulates.
AdBlue contamination
AdBlue is not fuel. In a diesel tank it can crystallise and corrode fuel-system components, so keep the ignition off and call for advice.
