Description

BP Energear 80W-90 is a multigrade gear oil from the Energear line for manual gearboxes and other transmission units. In cold weather it makes gear changes easier than a monograde oil does.

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

Typical figures: kinematic viscosity 13.9 mm²/s at 100 °C and 142 mm²/s at 40 °C, viscosity index 101, pour point -30 °C, flash point 234 °C, Brookfield viscosity at -26 °C 120,000 mPa·s.

Application

Manual gearboxes and other transmission units that call for an API GL-4 oil.

Worth knowing

Two Energear 80W-90 oils claim GL-4: this one and Energear HT 80W-90. HT adds GL-5, MB 235.0, MAN and Scania approvals and declared compliance with ZF classes, so where the documentation calls for one of those codes, HT is the only one of the pair that will do: this oil has no official approvals. Hot, HT is also thicker, at 17 mm²/s at 100 °C. Energear Axle 80W-90 is barely different in viscosity, 14.2 mm²/s against 13.9 mm²/s, but it is GL-5, not GL-4.

It is worth setting this oil’s own figures against the SAE J306 limits. Its 13.9 mm²/s at 100 °C is only just above the grade 90 floor of 13.5 mm²/s, while its Brookfield viscosity at -26 °C, 120,000 mPa·s, leaves some headroom below the 150,000 mPa·s limit for 80W. The article on the figures in an oil data sheet explains how to read viscosity and low-temperature values.
