Hightec ADDITIVES —

A BIG PLUS FOR YOUR CAR

ROWE stands for German engineering skill and high quality lubricants that are 100% made in Germany. Uncompromising quality, efficiency and reliability are the standards we also apply to our fuel, engine and coolant additives. Our high-performance additives are more than just supplements – they are key technologies for clean engines, sustainable performance and smart problem solving.

CLEAN. PROTECT. MAINTAIN.

Engines operate under extreme conditions. Even the smallest deposits can significantly impair performance, efficiency, and service life. Additives play a key role in cleaning and maintaining the fuel system. In short, they fulfill three functions: cleaning, protecting, and maintaining. Of course, they are no substitute for proper maintenance, but they have a decisive influence on clean and safe vehicle operation. When used correctly, our products improve the performance, efficiency, and service life of the vehicle—whether it is a used or new car.

MOTORSPORT DNA FOR YOUR EVERYDAY LIFE

With our additives, we offer one of the highest-quality
product ranges on the market, which meet our high standards—not least known from the motorsport activities of ROWE RACING. Our high-performance lubricants are also able to meet the highest demands of modern vehicle technology. Not only do they ensure extremely effective cleaning of internal engine components, they also perfectly complement our high-quality lubricant portfolio – for clean systems, maximum efficiency, and maximum service life.

EFFECT THAT GOES UNDER THE HOOD

Every engine has its own story. Some have millions of kilometers on the clock, others have just opened their first chapter. But no matter whether old or new, every engine deserves care that goes beyond the ordinary. Our additives are the invisible heroes inside your vehicle. They clean where no wrench can reach. They protect components that work under maximum load every day. And they maintain your engine so that its performance remains at a consistently high level. Our fuel, engine, and coolant additives bring together what drives us—quality, passion, and responsibility. Discover our products and see for yourself:

FOR GASOLINE ENGINES

Our high-quality gasoline additives deliver increased performance and efficiency. They clean the entire fuel system, prevent deposits, and reliably protect engines from wear. For noticeably better performance and sustainably clean operation.

FOR DIESEL ENGINES

Our diesel additives are of the highest quality, promote clean injection, increase the cetane number, and offer reliable protection against corrosion. They increase fuel efficiency and extend the service life of modern diesel engines—even under the most demanding conditions.

FOR ENGINE OILS

Our highly effective engine oil additives increase lubrication performance, reduce friction, and prevent harmful deposits. They ensure long-lasting protection, maximum cleanliness, and maximum efficiency—so that engines continue to operate reliably and powerfully even under extreme loads.

FOR COOLING SYSTEMS

Our proven coolant additives keep systems free of deposits, prevent corrosion, and ensure consistent heat transfer. They offer robust protection for a wide range of cooling systems—for reliable engine performance and longer component life.
