7 Ways to Avoid Wrong Fuel in Your Car – Tips & Prevention

Putting the wrong fuel in your car can cause serious engine damage and expensive repairs. Whether it's petrol in diesel or diesel in petrol, acting quickly is crucial. Here are seven practical ways to avoid misfueling and what to do if it happens:

1. Check Pump Colour Codes – Most UK stations use colour-coded pumps: red for diesel, green for petrol. Always double-check before pumping, especially at night or in unfamiliar areas.

2. Look for Misfuel Caps – Some pumps have a small cap that covers the fuel nozzle. If you see a cap, it's likely diesel. Remove it before pumping to avoid accidental petrol refills.

3. Use the 'One-Pump Rule' – Only use one fuel pump per refuel. Switching between pumps mid-fill can confuse the system and lead to wrong fuel.

4. Be Mindful of Rental Cars – Rental vehicles often have identical fuel caps and pumps. Always confirm with the rental company which fuel type is correct before refuelling.

5. Park Facing the Pump – When parking, position your car so you're facing the pump. This reduces the chance of accidentally pumping the wrong fuel.

6. Use a Fuel Identifier App – Apps like FuelCheck can scan pump codes and alert you to potential mismatches. Available in the UK, these tools add an extra layer of safety.

7. Never Start the Engine – If you suspect wrong fuel, do not start the engine. This prevents contamination of the fuel system. Contact EEK immediately for tow-to-workshop recovery.
