Police warning of ‘dirty oil’ car sale scam

Fraudsters distract car sellers and then interfere with the vehicle by pouring oil into the coolant reservoir or on to hot engine parts

WILTSHIRE Police are warning of a rise in so-called ‘dirty oil’ scams targeting people selling cars privately, where criminals attempt to force a sale at a fraction of the vehicle’s true value.

They pose as genuine buyers, often arriving in pairs and appearing enthusiastic and knowledgeable. While one distracts the seller by asking about paperwork, the boot or a test drive, the other interferes with the vehicle. This may involve pouring oil into the coolant reservoir or on to hot engine parts.

Shortly afterwards, the car appears to suffer a dramatic failure, often producing thick smoke. The fraudsters then claim the engine is ruined and offer a much lower price, suggesting they are helping by taking it ‘as scrap’.

There are clear warning signs. Buyers insisting on coming in pairs, one person keeping close to the engine bay, sudden ‘catastrophic’ failure during a short drive, and pressure to accept a low offer immediately should all raise concern. Claims that repairs will cost thousands without proper inspection are another red flag.

To protect yourself, never leave buyers alone with your vehicle and keep it in sight at all times, especially if the bonnet is opened. Have someone with you where possible.

Check the car before and after viewings for oily residue or fresh contamination, and consider taking photos beforehand. Be sceptical of sudden failures and trust your instincts.

If something feels wrong, stop the viewing and refuse the sale. Report incidents to Action Fraud at actionfraud.police.uk.
