of dangerous remainings when it is combusted, which
keeps the components of the engine more clean. This
extends the life of the engine. Husqvarna alkylate fuel is
not available in all markets.
Two-stroke oil
CAUTION: A poor oil quality and/or too high

formulated for air-cooled engines. Consult your
servicing dealer when you select an oil.

engines, also referred to as outboard oil.
