STIHL fuels and lubricants

Designed for People, Machines and the Environment.

As the manufacturer of STIHL engines, we know precisely what our equipment requires to perform. That's why we develop and test the oils, greases and fuels for our machines ourselves in our own STIHL laboratory, at numerous testing stations and in field tests around the world.

At STIHL, chemists, engineers and users of our tools work together. In so doing, we achieve optimum results for people, machines and the environment. We call this principle the STIHL Optimum System.

The STIHL Optimum System

More than 500 employees work in the cutting-edge STIHL development centre with its in-house laboratory. Engineers and chemists work to harmonise STIHL fuels and lubricants with equipment to get the best out of them.

STIHL fuels and lubricants and equipment undergo extensive functional and endurance testing at over 100 test stations and machines can only make it to the market once they have passed this extreme strength testing.

In field tests, lubricants, fuels and equipment are tested under a range of different
operating conditions as no climate is the same.
