Red Line Gear Oils are designed to provide excellent low-temperature characteristics and improved gear protection at higher temperatures. Red Line Gear Oils will reduce differential temperatures 10-70 degrees F. Efficiency improvements between 1-5% are typical. The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line gear oils to carry higher loads compared to petroleum lubricants.
