DRIVERS have been told to urgently check their cars after fuel was 'contaminated' at a BP garage.
Experts have revealed the key signs to look out for if motorists think they have used dodgy petrol.
The incident unfolded in Rayleigh, Essex, where customers saw their vehicles grind to a halt shortly after filling up.
Weighing in on the mishap, experts said that one of the most common signs is involuntary speed fluctuations and failure to start.
John Wilmot, CEO of LeaseLoco told GB News: "Fuel contamination can cause your vehicle to break down and lead to costly repairs depending on the severity of the damage.
"Inspecting the appearance of the fuel in the tank can also help identify contamination - fuel should look clear and bright, so if it appears dark, cloudy, and has a layer of sludge, it indicates possible contamination."

He also said that there may be a "strange smell" produced by the suspicious liquid.
Similar issues unfold when drivers put diesel in a petrol car and vice versa - which happens 150,000 a year according to the RAC.
Bosses at BP have since confirmed that the contaminated pump at the garage in London Road has been closed.
The "affected tank" has been isolated with the site now open again and operational.

An investigation is now underway to prevent further incidents like the one on January 10.
BP is also looking into the number of people who may have been affected.
The chain has 1,200 stations across the UK but it appears only the Rayleigh station was affected.
A BP spokesman said: “We have identified an issue at the site with a potentially contaminated tank, which is currently under investigation.
“The affected tank in question has been isolated and the site is now open and operational.
“We are taking steps to assess the potential impact and determine the number of people who may be affected.
“Any customers with concerns should contact our careline for support [email protected].”
