Why Putting Petrol in a Diesel Car Is a Problem

Diesel engines and petrol engines operate differently. Diesel fuel acts as a lubricant for the engine’s fuel system, while petrol is more volatile and designed for spark ignition engines. When petrol enters a diesel engine, it can cause:

• Damage to fuel injectors and fuel pump due to lack of lubrication

• Engine knocking and misfiring because petrol ignites differently

• Clogged fuel filters as petrol contaminates diesel residues

• Potential engine failure if the car is driven with the wrong fuel

  
  

The severity of damage depends on how much petrol was added and whether the engine was started after the mistake.

Immediate Actions to Take if You Put Petrol in a Diesel Car

Do Not Start the Engine

If you realize the error before starting the car, do not turn the ignition. Starting the engine circulates the wrong fuel through the system, increasing the risk of damage.

Turn Off the Engine Immediately if Already Started

If you have already started driving or the engine is running, switch it off as soon as possible. Continuing to drive will worsen the damage.

This process minimizes damage and gets your car back on the road safely.

How to Prevent Putting Petrol in a Diesel Car

Preventing this mistake is easier than fixing it. Here are some practical tips:

• Double-check the fuel pump label before filling up

• Look for diesel-specific signs on your car’s fuel cap or near the filler neck

• Use a key or cap that only fits diesel pumps if available

• Avoid distractions at the pump and take your time

• Inform other drivers who use your car about the correct fuel type

  
  

These simple habits reduce the chance of costly errors.

What Happens If You Drive After Putting Petrol in a Diesel Car

Driving with petrol in a diesel engine causes the wrong fuel to circulate through the system. This leads to:

• Reduced engine performance and power loss

• Increased exhaust smoke and unusual noises

• Potential stalling or failure to start

• Severe damage to fuel injectors and the fuel pump

  
  

If you notice any of these symptoms after refueling, stop driving immediately and seek professional help.

Cost Implications of Putting Petrol in a Diesel Car

Repair costs vary depending on how quickly you act and the extent of damage. Early intervention can keep costs low, mainly covering fuel system cleaning and filter replacement. Delayed action may require:

• Replacing fuel injectors

• Repairing or replacing the fuel pump

• Engine repairs or rebuilds in extreme cases
