PETROFLO AUTOMATIC TRANSMISSION FLUID meets or exceeds the requirements of General Motors Corporation as a Dexron III product and FORD as a Mercon product and may be used in cars requiring FORD type CJ and H fluids. It can be used in off-highway transmission, power steering, and other hydraulic systems requiring an Allison C-4 fluid. It meets the exacting industrial hydraulic oil demands of Denison HFO, Vickers Vane and Sundstrand Piston Pumps. PROPERTIES AND BENEFITS: 1. Strict viscosity control promotes smooth, quiet transmission of power. 2. High viscosity index promotes high lubrication film strength at elevated operating temperatures and excellent fluidity at low starting temperatures. 3. Lower co-efficient of friction-enables clutch plates to engage slowly and gradually as the transmission shifts. 4. Outstanding oxidation stability prolongs life of oil and cleanliness of transmission by resisting deposit formation. 5. Anti-corrosion and anti-rust fluid treated with special chemical inhibitors to protect vital parts against premature failure due to corrosion and rust. 6. Anti-foam protection. Anti-wear agents protect and extend service life of precision parts subject to high friction and wear. 7. High flash point stable at high temperatures. When choosing the oil for the transmission units, they usually focus on two criteria: the specific loads acting in the mechanism and the speed of relative slip. Depending on this, gear oils are selected, differing in viscosity and the number of additives, in the first place, extreme pressure. The latter, as a rule, contain sulfur compounds that cause chemical changes (modification) of metals in critical regimes. The surface layer of the material does not break out, forming scuffs, but turns into a thin film, which subsequently becomes a product of wear. Despite the fact that the metal is chemically "corroded", the overall wear under severe operating conditions is less.
