Caterpillar and Allison have both set standards for these types of products, becoming guidelines for the cross reference of acceptable fluids. PRO-TAC IV Excel exceeds the specifications established by these manufacturers, setting a standard for fluid life and protection.

Texas Refinery Corp.’s PRO-TAC IV Excel offers excellent low temperature fluidity. PRO-TAC IV Excel’s ability to flow well in colder temperatures helps to assure that vital components are protected and will not experience increased wear, especially during cold weather start up.

Equipment is run in a variety of environments and by a variety of operators. Foaming, heat, seal deterioration, and wear are common to units using TO-4 fluids. Often run for extended periods of time or over greater distances than originally recommended, PRO-TAC IV Excel provides the added protection designed for the added work these units experience.

With industry experts touting the advantages of extended drain intervals, we encourage equipment owners to use products designed to accomplish this feat. Not all products contain adequate additive packages or begin with the quality base oils necessary to establish effective, safe, and cost efficient extended drain intervals. PRO-TAC IV Excel was designed with this purpose in mind.

A truly unique characteristic of PRO-TAC IV Excel is the addition of tackifiers. This additional additive helps to maintain superior protection to gear components. By maintaining a film of protection, wear is reduced dramatically. In addition, as wear is reduced the oxidation process is slowed and the product performs more effectively for a longer period.
