Transmission Drive Train Oil

PRODURO™ TO-4+ products are a line of Transmission and Drive Train Oils formulated to meet or exceed Caterpillar’s TO-4 requirements for transmission and drive line fluids.

PRODURO TO-4+ UHP can help increase equipment productivity and decrease operating costs. During a two+ year long customer trial, the fluid demonstrated the ability to meet the requirements of the Caterpillar TO-4 specification, increase equipment life by up to 6% and deliver significant cost savings based on 25 units for a large Canadian mine operating across two sites. PRODURO TO-4+ UHP is designed as an SAE 10W-40 grade although this fluid has excellent low temperature properties and meets pumpability requirements of an SAE 5W grade.

PRODURO™ TO-4+ oils are also available in six other grades: SAE 10W, 30, 50, 60, XL Synthetic Blend LoTemp and Synthetic All Season. The last two products are formulated with special base oils which confer multigrade pumpability equivalent to SAE 0W-20 and SAE 5W-30 respectively.

They have been fully tested and comply with the performance requirements of Caterpillar TO-4, API GL-3 (Inactive) and the obsolete categories of Allison C-4 (transmission), API CD (Diesel Engine), Caterpillar TO-2 and Eaton/Vickers (M-2950/I-280-S). They are recommended for use in hydraulics, manual transmissions and drive lines, where a TO-4 oil is recommended. Other OEMs include Komatsu's KES 07.868.1, Komatsu-Dresser, Dana Power shift, Tremac and Euclid Specifications.

From time to time, Caterpillar publishes revisions to lubricant recommendations for their various equipment. Users are encouraged to visit the CAT website to download the most recent version of these recommendations, document SEBU 6250.

¹Powershift and Hydrostatic transmissions applications may need higher viscosity fluids for added film thickness protection if used in continuous operation or under extreme heavy loading. Refer to SEBU 6250 (Most recent) for further details.

PRODURO™ FD-1 products are Petro-Canada Lubricants primary recommendation for the final drives and axles of Caterpillar off-highway equipment, especially those that operate under severe conditions.

PRODURO™ FD-1 60 provides improved gear and bearing life in final drives and axles and can be used in final drives and axles that previously specified TO-4 lubricants and do not contain friction material and/or wet brakes. The recommended drain interval for FD-1 60 is 4000 hours for off-highway trucks, final drive and rear axles instead of the 2000 hour interval typically recommended for TO-4 fluids.

PRODURO™ FD-1 Synthetic is for equipment that works in extreme colder temperatures with frequent heat cool cycles. It provides improved gear and bearing life in final drives and axles and can be used in final drives and axles that previously specified TO-4 lubricants. The recommended drain interval for FD-1 Synthetic is up to 6000 hours for off highway trucks, final drive and rear axles instead of the 2000 hour interval typically recommended for TO-4 fluids and provides even better extended drain capability than PRODURO™ FD-1 60.

PRODURO™ FD-1 products should not be used in compartments containing friction material unless an FD-1 type of product is specified. This product is not designed for use in engines, transmission hydraulic systems, or older Caterpillar (789 series haul trucks) final drive technology where ZDDP anti-wear additive technology is better suited.
