Although gearboxes and transmissions serve the same operational scope their lubricants differ. Generally, gear oils are used in manual gear boxes and transmission fluids in automatic transmissions. However, oils used in manual gearboxes are thicker, more viscous oils to withstand high temperatures and be able to function under extreme pressure. Those used in automatic transmissions are less viscous and thinner gearbox fluids which contain detergents and act as coolants while they contain further additives to improve their life expectancy.

BP® ENERGEAR range of automotive gear oils have been designed for use in a wide range of gear units with spur, bevel or helical gear design, including synchronized manual gearboxes, transmissions and axles under moderately severe load and pressure conditions. They were applicable for passenger cars, light and heavy trucks as well as agricultural and building machinery providing effective protection of gear transmissions and prolonging component life. The Energear EP range conformed to the requirements of API GL-4.

BP® ENERGEAR gear oils are replaced by respective BP® CASTROL® gear oils and transmission fluids developed to protect against wear, prolong gear life, and help to deliver optimum gear performance. They  are formulated to meet or exceed the highest industry standards featuring thermal stability, wear protection, seal compatibility and hydrolytic stability. A range of gear and transmission lubricants are offered for mobile and stationary equipment.
