Valvoline DT Transmission 30 is a heavy-duty transmission oil formulated for construction, mining, and earthmoving equipment that requires robust drivetrain lubrication under extreme operating conditions. Produced from high-quality base oils and specially selected additives, this oil meets the most rigorous performance requirements demanded by modern heavy equipment in severe service environments.

The SAE 30 viscosity grade provides a thicker oil film that delivers superior protection under heavy loads and elevated operating temperatures. This makes DT Transmission 30 the preferred choice for equipment operating in warm climates, tropical conditions, or high-ambient-temperature environments where higher-viscosity lubricants are needed to maintain adequate film strength and prevent metal-to-metal contact in heavily loaded components.

DT Transmission 30 is designed for use in transmission systems and as a hydraulic fluid in heavy equipment. It provides excellent wear protection for gears, bearings, clutch packs, and hydraulic pump components, helping to maximize service life and minimize repair expenses. The oil's carefully formulated friction characteristics ensure smooth and reliable wet brake operation, which is essential for safe equipment handling on slopes, in confined spaces, and during precision work.

This oil is recommended for Caterpillar heavy trucks, excavators, wheel loaders, dozers, and other earthmoving equipment, as well as any machinery that requires lubricants meeting advanced drivetrain performance specifications. It is not intended for use as engine oil. Equipment managers and maintenance professionals rely on DT Transmission 30 to deliver consistent, dependable performance in the harshest construction, quarrying, and mining applications where equipment reliability directly impacts productivity and safety.
