Putting petrol in a diesel car is a common mistake that can cause serious damage to your vehicle. If you find yourself in this situation in Birmingham, knowing the right steps to take can save you time, money, and stress. This guide explains what happens when petrol is added to a diesel engine, how to respond immediately, and where to get professional help in Birmingham.
What Happens When You Put Petrol in a Diesel Car birmingham
Diesel engines rely on the lubricating properties of diesel fuel to keep the fuel pump and injectors working smoothly. Petrol, on the other hand, is more volatile and lacks these lubricants. When petrol enters a diesel engine, it can cause:
Damage to fuel pump and injectors due to lack of lubrication
Engine knocking or misfiring because petrol ignites differently than diesel
Reduced engine performance and possible stalling
Potential long-term engine damage if the car is driven with the wrong fuel
Even a small amount of petrol in a diesel tank can cause problems, but the severity depends on how much petrol was added and whether the engine was started.
Immediate Steps to Take After Realizing the Mistake
If you notice you have put petrol in your diesel car before starting the engine, do not turn the ignition on. Starting the engine circulates the petrol through the fuel system, increasing the risk of damage.
If you have already started the engine, stop driving immediately and turn off the engine as soon as it is safe to do so.
Here’s what to do next:
Do not try to drive the car to a garage or home. Driving spreads petrol through the fuel system.
