Abstract
A canister for releasing oil additives into oil in an internal combustion engine, hydraulic equipment, or automatic transmission includes a container having an inlet, outlet, and interior volume. Partitions divide the interior volume into a plurality of different individual compartments, and a plurality of discrete shapes of thermoplastic material with oil property improving additives are disposed within at least a plurality of the individual compartments. The partitions may comprise a metal grid, the container may be disc-shaped with perforated end walls, and the container desirably fits between the engine block and a conventional oil filter. Alternatively the container may comprise an elongated tube having first and second end faces with the partition comprising disc-shaped elements extending in a plane substantially transverse to the dimension of elongation of the container. The inlet may have a metering tube, and the outlet a screen, and the container is connected between the engine block and an oil filter.
