The Good News

Diesel in a petrol car is generally less catastrophic than petrol in diesel. Because petrol engines use spark ignition (not compression), they're more tolerant of fuel contamination.

However, diesel won't ignite properly in a petrol engine, causing poor running, misfires, excessive smoke, and potential catalytic converter damage if driven for too long.

What Happens When You Put Diesel in Petrol?

Symptoms You May Notice:

  • Engine Misfires - Diesel doesn't ignite well with spark plugs
  • Excessive Smoke - Black or grey smoke from the exhaust
  • Loss of Power - Engine struggling, hesitation on acceleration
  • Engine May Stall - Could cut out completely if concentration is high
  • Check Engine Light - Usually triggers fault codes

The sooner we drain the contaminated fuel, the less chance of long-term damage.
