I use this oil in the lower unit of a 150hp EVinrude
The oil quality is very good for use in marine outoard lower units.

Gear lube
Very handy tube for adding or replacing lower unit gear lube in a small outboard motor. Cut small section of tube nozzle off and then nozzle fits tight in the filler hole with no leakage. Screw cap works well to seal tube when saving extra not used for another fill up. My vintage outboard (1970) called for this type of gear lube.
