Viscosity testing

Your work always goes smoothly because our lab never stops working.

Show your STIHL you care
Every tool is only as good as the fuels, oils and lubricants that go into it. As you'd expect, we've developed our own rigorously tested range specially suited for STIHL machines, designed to give optimum performance and minimum wear. Because we believe the best machines deserve the best treatment.

Keep your STIHL running smoothly
During development, there are a number of questions we ask. How much residue do our fuels leave during combustion? How does the tool run from a cold start? How biodegradable is the product? What’s the oil viscosity like at different temperatures? Once the test results are in, our laboratories work hard to find the best formulae for every machine through extensive research, development and testing. Because at STIHL, we do like everything to run smoothly.
