This is Castrolâ€™s latest consumer ad campaign in action.
The oil manufacturer is using traffic cameras to advise drivers about the right oil for their cars.
Almost 50% of Britainâ€™s drivers are currently using the wrong grade or specification of oil in their cars and it could cost them up to Â£5k to repair any resulting damage, according to Castrol.
The campaign encourages drivers to drive past specially installed cameras in 5 locations around London safely in order to get â€˜flashedâ€™.
But rather than identifying people driving too fast or who havenâ€™t paid the congestion charge, the cameras will spot check cars and will flash a personalised message to the driver.
The roadside cameras will pick up passing carsâ€™ registrations and match them to the make and model of car via the DVLA database.
A message to the driver with the correct oil recommendation for their carâ€™s engine will then be flashed on digital billboards further down the road.
â€œThis new initiative means that for once drivers may actually be pleased about being caught on camera,â€ said motoring expert Quentin Willson.
The five trial sites in London are:
- Blackfriars â€“ Stamford Street
- Lambeth â€“ Vauxhall Cross
- Hammersmith â€“ Fulham Palace Road
- Hounslow â€“ Chiswick roundabout
- Kensington & Chelsea â€“ Warwick Road
