Balmerol Protomac C4 Series oils are manufactured using high viscosity index (VI) baseoil and selected additives. The synergistic blend of additives provides excellent shear stability as well as protects from rust and oxidation. These oils resist foam generation and thereby reduce wear. Balmerol Protomac C4 Series oils meet TES 228 specifications for hydraulic transmission fluid type C4 of Detroit Diesel Allison.
