I want to share my experience with the Polytron products.

For more than two years I have used the Polytron products in all my machines. To know:

– Ponsse ergo Wood harvesting machine
– stihl ms661
– stihl brush cutter

The Ponsse runs on a full synthetic motor oil 10w40 from Polytron, addition to the fuel and Polytron MTC in the pump casing, hydraulic oil, high / low bucket and final drives. The extension crane is also lubricated with Polytron spray and the entire machine with Polytron EP2 grease. The Ponsse has now been running 11600 hours.

My stihl machines are two-stroke engines running on alkyd fuel (aspen or motomix) and I add Polytron FC to the fuel.

After more than two years of use, I can conclude that I have less loss-related damage. The fuel consumption of the Ponsse has also dropped from 13 l / h to 12 l / h.

A number of components, such as the gearbox for the crane’s swing, have already passed their expected service life and are not yet up for revision.
I also have a reference, colleague entrepreneurs with Ponsse machines that replace expensive components on a much larger scale.

The savings are not just less damage, but also less service. The change intervals for the engine and grease-lubricated components have been considerably extended.
An important difference is that I have determined by measurements before and afterwards that the operating temperature of the pump box of 90 degrees Celsius is now around 70 degrees Celsius.
