99% of fuel theft can be attributed to the practice of skimming. This is the terminology for siphoning off the top 25-50 litres of fuel from the tank on a regular basis. This practice makes it extremely difficult to identify theft using fuel monitoring resources. Often this theft is conducted internally; therefore these thieves are highly unlikely to damage the fuel tank. Additionally, if a 3rd party thief sees a Truck protected by TankSafe, they are more liable to attack a truck that has no device fitted.
