Parent Petroleum Co. HT/4 Fluid 60 1042535

larger image 76 HT/4 Fluid is a shear stable transmission and drive-train fluid specially designed to meet and exceed the performance requirements of the Caterpillar TO-4 specification. It provides substantially improved friction and antiwear performance compared with older API CD/TO-2 quality fluids, resulting in longer equipment life and reduced risk of field failure. It has excellent oxidation stability, outstanding seal and friction material compatibility, and provides superior rust and corrosion protection. The SAE 10W and 30 viscosity grades also meet the performance requirements of Allison C-4.
