About Us

"Every year, at least 150,000 UK-based motorists will fill their diesel vehicles with petrol."

AA, RAC and Green Flag

"You bought a diesel car for better economy. Then, one day, you put petrol in the tank. Whatever you do next, DON'T UNLOCK THE DOORS."

Many diesel vehicles use the unlocking of the doors as the trigger for the fuel pump to prime the engine. If this happens, it may already be too late to prevent expensive damage to the vehicle!

Our Solution

Our solution (Patent No: GB2435037 and 0719853.4) 

The Fuel Angel Misfuelling Prevention Device replaces the existing filler cap and, once fitted, prevents you from accidentally putting a petrol nozzle into a diesel filler neck.

The device can be fitted onto most existing diesel vehicles - whatever the age. If you would like to fit the device to all the vehicles in your fleet, please enter your details in the Expressions of Interest form and we will give you a quote for a fleet discount.

The Fuel Angel - Misfuel Prevention Device provides the solution while adding intrinsic second-hand value to any diesel vehicle.
