STIHL Pouring Aids for Chain Oil

Aspen Two stroke oil is a fully-synthetic engine oil for all types of air-cooled two stroke engines, both for mixing with petrol when more than 2% oil is required and for engines with separate lubricating systems. It is designed especially for demanding two stroke engines used in forestry and gardening, and other small machines which are often cold started.

In general, outboard oil should be used if the motor is water-cooled. If the motor is air-cooled, two stroke oil for air-cooled engines should be used, e.g. Aspen Two stroke oil.
