NOTICE
Biodegradable chain oil must be resistant to aging, since it
will otherwise quickly turn to resin. This results in hard
deposits that are difficult to remove, especially in the area of
the chain drive and chain. It may even cause the oil pump to
seize.
NOTICE
Waste oil does not have the necessary lubricating properties
and is unsuitable for chain lubrication.
