AVENO TO-4 SAE 40 is a special transmission oil for supplying construction machinery and tractors. AVENO TO-4 SAE 40 meets the increased demands of the Caterpillar TO-4 specification and is therefore suitable for use in gearboxes, final dives, hydraulic systems, wet brakes and clutches which require this specification.

Application notes:
AVENO TO-4 SAE 40 ensures maximum wear protection in various gearboxes, such as side drives and differentials, it optimizes the friction coefficient in power-shift transmissions, wet brakes and clutches and guarantees maximum service life for the units.
