Accidentally filling your diesel vehicle with unleaded petrol can be stressful, but it's important to stay calm and act swiftly to minimize the risk of damage. Diesel engines are highly sensitive to the type of fuel used, and petrol can have a detrimental effect if not appropriately addressed.
Why Unleaded Petrol Can Harm Diesel Engines
Diesel engines operate differently from petrol engines and require a specific fuel type to maintain performance. Here's why putting unleaded petrol in a diesel vehicle can be problematic:
Petrol affects diesel lubrication: Diesel fuel provides essential lubrication to the fuel pump and injectors, which helps the engine function smoothly. Petrol, however, strips away this lubrication, leading to increased friction and potential damage to these components.
Contamination of the fuel system:Even a small amount of unleaded petrol mixed with diesel can lead to a breakdown of the fuel system, clogging fuel filters and damaging injectors.
Engine misfiring and stalling:If petrol circulates through a diesel engine, it can cause the engine to misfire, lose power, or stall completely. If left unchecked, this can lead to costly repairs.
What to Do If You've Put Unleaded in Your Diesel Vehicle:
Don't start the vehicle: If you realize the mistake before starting your engine, you've saved yourself from significant potential damage. Leave the engine off and avoid turning on any electrical systems that could cause the fuel to circulate.
Stop immediately if driving:If you've already started the car or driven a short distance, stop the vehicle as soon as it's safe. Turning the engine off prevents further damage to the fuel system and engine.
Get professional help immediately:The only way to fix the issue is to drain the unleaded petrol from your diesel tank and flush the system. You'll need an experienced technician to carry out the procedure safely.
