Description

BP Energear 140 is a high-viscosity monograde SAE 140 gear oil from the Energear line for manual gearboxes and for spur, bevel and helical gears in cars, trucks, agricultural and construction machinery.

It is rated API GL-4 and carries no official carmaker approvals.

Typical figures: kinematic viscosity 29 mm²/s at 100 °C and 420 mm²/s at 40 °C, viscosity index 97, flash point 196 °C, density 912 kg/m³. The data come from the data sheet for the Middle East market.

Application

Manual gearboxes and spur, bevel and helical gears in cars, trucks, agricultural and construction machinery.

Worth knowing

Three oils in the Energear line share the hot grade 140, and apart from this one only Energear 85W-140 claims API GL-4. The winter part of the designation is what separates them: for 85W, SAE J306 allows no more than 150,000 mPa·s at -12 °C, while for a straight 140 it sets no cold limit at all. Hot, this oil is slightly thicker, 29 mm²/s at 100 °C against 26.5 mm²/s, and both figures sit inside the grade 140 band of 24.0 to 32.5 mm²/s. A shared hot grade does not mean that a unit specified for SAE 140 will take an all-season 85W-140, though; that is the unit maker’s call.

The third 140 oil, Energear Axle 85W-140, is GL-5 rather than GL-4. According to the article on choosing between GL-4 and GL-5, a GL-5 oil goes into a gearbox that calls for GL-4 only with the gearbox maker’s express permission.
