Protect your
entire fleet

Every day, hundreds of drivers of passenger cars accidentally pick the wrong fuel.

That is normal. In the case of company cars with changing drivers, it is easy to make mistakes at the petrol station because the private car needs a different fuel or the company car is simply unknown / new to the driver. Mixed fleets with diesel and petrol cars are another problem. From the moment the wrong fuel is in the tank, the driver and vehicle are no longer mobile.

The result is that customer appointments cannot be realised and delivery times cannot be met. Downtime and loss of earnings arise for companies. This causes lots of extra work for fleet management: procurement of a replacement vehicle and claims handling. To prevent all this in a simple and cost effective way, we have developed the Tankfreund.
