Diesel into Petrol Car London:  Devastating or Now Fixable?

Diesel into Petrol Car London:  Devastating or Now Fixable?
Driving mistakes can happen to anyone. One of the most common ones is accidentally putting diesel into a petrol car in London. While it may seem like an innocent mistake, it can seriously affect your vehicle’s performance and engine health. If this has happened to you or someone you know, don’t panic.

This article will provide helpful tips and advice for those who have accidentally put diesel into their petrol car in London, including where to get help and advice from experts.

So, if you’ve done the deed and need some help, read on, and we’ll take you through what to do next.

First Things First: Don’t Start the Car

Although it might be tempting to start the car after discovering your mistake, resist the urge. Diesel mixed with petrol will cause significant damage to your car engine and fuel system if allowed to circulate through. Starting the vehicle will only worsen matters and increase the repair cost significantly.

Diesel into Petrol Car London: Where Does Diesel Go?

It is essential to understand how diesel enters your petrol engine and where it goes once inside. This will help you determine what parts need replacing or cleaning and how much you should expect to pay for repairs eventually. 

Diesel fuel typically enters the petrol tank when refueling, but sometimes it gets sucked up through ill-fitted or insecurely installed air filters. Diesel then circulates through valves, injectors, spark plugs, catalytic converters, and other components of your vehicle’s fuel system before reaching the engine itself.

What Happens When Diesel Enters a Petrol Engine?

When diesel mixes with petrol in a car’s combustion chamber, several things happen that can lead to catastrophic damage and decreased performance:

  • The wrong fuel mixture affects the combustion process due to differences in properties between diesel and petrol. This includes density and octane ratings, resulting in poor acceleration, knocking sounds from the engine due to misfiring, or complete failure of ignition systems.
  • Diesel withstands higher temperatures than regular gasoline. This means it will stay liquid longer at high temperatures. This causes excess heat build-up over time that can eventually melt components such as spark plug tips.
  • Diesel contains higher sulphur levels than gasoline. Sulphur reacts with certain metals forming deposits that clog up fuel lines. This leads to increased pressure build-up during combustion cycles. The result is valves and gaskets blowing out and wear on piston rings.
  • Diesel has lower lubrication characteristics than gasoline meaning its presence can severely reduce oil quality inside an engine. This leads to wear on delicate internal components that could result in costly repair bills. This damage can include premature valve stem seal failure or camshaft destruction. These issues are mainly due to a lack of lubrication throughout critical engine parts.

How to Mitigate Diesel Damage 

To prevent long-term damage from happening due to diesel entering a petrol engine, these steps are recommended by experts:

– Before starting the vehicle, check for any signs of leaking fuel around valve covers, spark plugs, or intake manifolds. Change oil immediately if there appears to be any contamination with diesel fuel.

– Have all filters changed or thoroughly cleaned if possible (air filter is the priority.) Inspect all hoses connected directly to the motor area for any signs of leakage.

– Drain the tank completely if more than 15 litres (4 gallons) were put into the petrol tank by mistake. This prevents a further dilution cycle within the gasoline/diesel mix inside the motor compartment.

– Replace all spark plugs (especially those closest to cylinders) since they are most likely covered by sulphur residue left behind by the diesel combustion process. This makes them prone to malfunctioning at some point – even after a successful flushing procedure.

– Run the ‘flush procedure’ only when necessary (adding a specific type of chemical detergent into the tank while running the engine on a low rpm setting, then switching back to the original gasoline grade afterward).
