In a world where sustainability and innovation are increasingly important, Tunap has emerged as a pioneer in chemical maintenance and cleaning products for vehicles. This German company, founded in 1974, develops solutions that not only make vehicles perform better, but also take people and the environment into account.

A sustainable vision of maintenance
Tunap is more than a manufacturer of maintenance products; it is a partner for car manufacturers and garages offering smart and sustainable solutions. With its own laboratories and production facilities in Western Europe, the company ensures the highest quality standards and focuses on both preventing and solving pollution problems in modern internal combustion engines.
Sustainability is a core value here. Tunap combines economic, social and environmental responsibility to make a positive impact. This is evidenced by eco-friendly production processes, compliance with strict environmental legislation and initiatives such as the TUNBottle, packaging made from 80% recycled plastic. Tunap also works with ClimatePartner to fight plastic pollution in oceans and support renewable energy projects.


Continuous development of new solutions
Behind Tunap’s cutting-edge products is a team of 25 experts in its laboratory in Wolfratshausen, Germany. Every day, they analyse materials and processes to develop new solutions for contemporary and future challenges. This intensive research process leads to innovative patents and high-quality products that are used worldwide.
With more than 30,000 customers and a team of 700 employees across Europe, America and Asia, Tunap offers a complete service: from development and production to sales. This makes the company not only a reliable partner for the automotive industry, but also a player shaping the future of sustainable maintenance.
Tunap proves that technological progress and care for people and the environment can go hand in hand. With a continuous focus on innovation and sustainability, the company continues to pave the way for a cleaner, more efficient and environmentally friendly future.
Modern injection techniques require maintenance
Diesel injection systems have advanced enormously in recent years. Everything here is aimed at reducing harmful emissions. Of course, favourable fuel consumption also plays a role.
Diesel fuel has also changed over the years. Just a small amount of contamination can lead to expensive repairs.
To keep your fuel system in top condition, preventive maintenance is necessary. This can easily be combined during maintenance operations. This involves using a cleaning fluid when changing fuel filters. In addition, a diesel additive is added to the fuel tank. In this way, the entire system from the fuel tank to the injection is addressed and failures can be prevented.

Powerful problem solvers
In the unlikely event that contamination problems do arise, Tunap offers a powerful solution. Running a diesel engine concentrated on a cleaning fuel can effectively remove contamination. This can prevent the early replacement of costly injectors in many cases.

In addition, diagnostic equipment can be used to measure injection system correction values. This makes it easy to take stock of the end result of a cleaning. A cleaned injection system contributes to optimal operation and minimal emissions.
All the facts at a glance
- The share of biofuel is rising.
- There is varying quality of organic blends.
- Biofuel attracts moisture (hygroscopic).
- Biofuel can degrade and cause pollution.
- Injection systems are becoming more sophisticated and sensitive to contamination.

Indispensable in the workshop
Tunap combines innovation, sustainability and high technology to make vehicles perform optimally and reduce harmful emissions. With indispensable maintenance and cleaning products, garages can prevent and solve pollution problems, improve engine performance and reduce costly repairs. Thus, Tunap is not only a sustainable choice, but also an essential partner for an efficient and reliable garage.
