When an emergency vehicle is out of action, it is missing exactly where lives are at stake. Shift work, changing drivers, stress and fatigue make reaching for the wrong nozzle a daily risk, all the more so in mixed fleets of diesel and petrol vehicles. The [Tankfreund misfuelling protection](https://tankfreund.de/en/misfuelling-protection) hangs in plain sight above the fuel cap: on ambulances and patient transport vehicles, on police patrol cars, on the command vehicles of fire brigades and THW (Germany's Federal Agency for Technical Relief), and on the cars of care services. Whoever refuels has to lift it and sees the right fuel.

It is GTÜ-tested, fitted in two minutes and, on request, printed with your organisation's logo. More than 10,000 vehicles are already fitted with it, at aid organisations such as the German Red Cross (DRK), Johanniter, Malteser, ASB (Arbeiter-Samariter-Bund) and THW.

The maths

[**around €500**for a pump-out](https://tankfreund.de/en/misfuelling#costs)[**€5,000 to €10,000**for engine damage](https://tankfreund.de/en/misfuelling#costs)[**under €3**per vehicle for the Tankfreund](https://tankfreund.de/en/misfuelling-protection)

A single pump-out costs as much as Tankfreund tags for 100 vehicles. Insurance you will hopefully never need.

### All vehicles equipped with the Tankfreund

“When an ambulance is misfuelled, the damage quickly comes to €10,000 to €15,000 per incident. That is why we have equipped all our vehicles with the Tankfreund.”

**M. Stürmer**, DRK-Kreisverband Lüneburg

![Malteser logo](https://tankfreund.de/hubfs/website/logo-malteser.svg)

### Guaranteeing operational readiness

“We rely on the Tankfreund in our emergency vehicles to keep the volunteer units of disaster and civil protection ready for action at all times, to avoid lengthy and costly workshop stays and to prevent the effort and expense of a temporary replacement vehicle in the event of misfuelling.”

**C. Cossmann**, Malteser Hannover

![Rettungsdienst Oberbergischer Kreis logo](https://tankfreund.de/hubfs/website/logo-rettungsdienst-oberbergischer-kreis.png)

## Questions from emergency services

You'll find more answers on the product, fitting and ordering in the FAQ.

[All questions](https://tankfreund.de/en/faq)

How long does fitting take?

Around two minutes per vehicle: clean the surface above the fuel cap, peel off the protective film, press on firmly. No tools needed.

We already have stickers on the fuel cap.

Stickers are easily overlooked. The Tankfreund has to be lifted to refuel; Cambio CarSharing found it “considerably more effective than the usual stickers”.

It hardly ever happens to us.

The Tankfreund works like an insurance policy: a single pump-out costs about as much as Tankfreund tags for 100 vehicles.

Is it also suitable for fire brigades?

Yes, for all cars and vans, such as command cars, incident command vehicles and crew transport vans. It is not designed for trucks such as fire engines.

Can we have it with our logo?

Yes, with your organisation's logo and text. The design work is included, and the samples we send are unbranded.

## Test first, then decide.

We will send you a few Tankfreund tags free of charge to try out.

- Free of charge
- In the fuel you need
- No obligation
