T5X® Heavy Duty Motor Oil
Heavy-Duty Monograde Diesel Engine Oil
T5X Heavy Duty Motor Oil is a high-quality diesel engine oil designed for use in a wide variety of applications, including off-highway diesel equipment, farm machinery, marine engines, 2-stroke cycle diesel engines (in the appropriate viscosity grades) and mixed commercial fleets. It also may be used in some heavy-duty manual transmissions in trucks and buses.
T5X Heavy Duty is formulated to provide excellent wear protection, to minimize the formation of sludge and varnish, to protect against rust and bearing corrosion, and to resist foaming. It has excellent soot dispersancy to protect against abrasive wear and soot-induced oil thickening, and excellent oxidation resistance to help minimize deposit formation. The SAE 30 & 40 grades have low ash content to help minimize ash deposits and keep intake ports clear to maintain good power output in 2-stroke cycle applications.
T5X Heavy Duty SAE 30 and 40 meet or exceed the performance requirements of API Service Categories CF-2 and CF, and also may be used in applications where API CD quality oils are specified. They are particularly recommended for use in 2-stroke cycle diesel engines in transit buses and marine fleets running on low-sulfur diesel fuel.
T5X Heavy Duty SAE 50 meets or exceeds the performance requirements of API Service Categories CF and SL. It is primarily recommended for use in off-highway diesel equipment and mixed commercial fleets with both diesel and gasoline vehicles.
T5X Heavy Duty SAE 10W is intended for use in the hydraulic systems and hydrostatic transmissions of Caterpillar and other off-highway construction equipment. It is not recommended for use in engines.Applications
