2-STROKE ALKYLATE GASOLINE FOR SMALL ENGINES
WITH ASH-FREE FORMULA
2-stroke engines are still extremely popular. They are compact, of simple design and powerful. These advantages are in particular demand for hand-held equipment. To reduce the impact of pollutants on users and the environment, it is now standard practice to use alkylate petrol. As of July 1, 2015, it has been mandatory under the new Swiss standard SN 181163 for any added 2-stroke motor oil to have an ash-free formulation. The oil that has been used in Aspen 2 for around two years now complies with the new standard and is the result of the partnership between MOTOREX and Aspen.
