Engine oils

When changing the oil, it is important to use the correct oil. And selecting the right product is becoming increasingly complicated. Modern engines in passenger cars and commercial vehicles are becoming ever smaller and more powerful. Manufacturers are prescribing complex synthetic oils that can withstand higher engine pressure and at the same time achieve the desired fuel economy. We do not leave you alone in deciding on the optimum oil and advise you on selecting the right engine oil from our product portfolio.

Drivetrain lubricants

With the continuous development of vehicle technology in recent years, components around and in the drivetrain of passenger cars and commercial vehicles are becoming increasingly complex and require advanced oils to ensure their proper and reliable function. Only by using the right oil for your vehicle can you ensure that the transmission can perform its task without damage for the entire service life of the vehicle. In our product portfolio, we offer you a large selection of modern transmission oils for automatic transmissions as well as manual transmissions, axle and universal transmission oils. We will advise you personally on the selection of the right oil for your drivetrain.

Hydraulic fluids

Our selected product portfolio of high-performance hydraulic fluids from Aral and Castrol for commercial and construction machinery offers you excellent lubrication and cooling performance to optimize the efficiency and longevity of your hydraulic systems. Our range includes hydraulic fluids that meet and exceed the manufacturer specifications of e.g. Caterpillar, Cummins, Mack and Volvo. We will advise you personally on the ideal choice for your needs.

Lubricating greases

Vehicles and systems that are used under extreme conditions need the right greases to protect important components. Our product range includes a large selection of multi-purpose and special greases from leading manufacturers for outstanding protection even under the highest operating conditions. Whether lubricating bearings in commercial and construction vehicles or using greases according to manufacturer specifications in classic cars – the optimum grease can extend the service life and maintenance intervals of machines, increase productivity in the vehicle fleet and optimize bearing function. We can advise you personally on the right choice of synthetic multi-purpose and special greases for individual applications.

Brake fluids

The use of high-quality brake fluid is just as important as high-quality brakes. High stresses such as high-speed driving, heavy-duty transportation or extreme loads on the brake system due to downhill driving demand a high level of performance from the brake fluid. Selecting the right brake fluid for the respective type of car or commercial vehicle and changing the brake fluid regularly are essential for safe driving. We offer brake fluids for all types of vehicles and for driving under difficult conditions, as well as products with an extended safety reserve. We will provide you with personal advice on the right product.


High-quality and modern coolants ensure maximum protection against high thermal loads in car and commercial vehicle engines. The use of modern coolants can extend the lifespan of engines and minimize potential damage as well as downtimes. We offer a wide range of coolants from our partners Aral and Castrol. Together we will find the right coolant to meet your specifications and requirements.
