Description
BP Energear 90 is a monograde SAE 90 gear oil from the Energear line for gearboxes that run without severe frost.
It is rated API GL-4 and carries no official carmaker approvals.
Typical figures: kinematic viscosity 16.9 mm²/s at 100 °C and 187 mm²/s at 40 °C, viscosity index 96, flash point 282 °C.
Its pour point is only -6 °C, so this oil is not suited to cold climates.
Application
Gearboxes that call for an API GL-4 oil, in conditions where cold-weather operation is not the deciding factor.
Worth knowing
At 100 °C the straight SAE 90 and this line’s multigrade 80W-90 oils sit in the same band: SAE J306 gives grade 90 a range of 13.5 to 18.5 mm²/s, and the data sheets show 16.9 mm²/s for this oil, 13.9 for Energear 80W-90 and 17 for HT 80W-90. The difference shows up in the cold. The standard sets no cold limit for a grade without a W, and this oil reaches its pour point as early as -6 °C. For Energear 80W-90 the data sheet gives 120,000 mPa·s Brookfield at -26 °C, within the 80W grade, and a pour point of -30 °C; HT 80W-90 has a pour point below -24 °C. Energear 80W-90 has the same API GL-4 and likewise carries no approvals, but whether a gearbox will take a multigrade instead of SAE 90 is for its manual to say. The limits of every gear oil viscosity grade are brought together in the SAE J306 table in the gear oil guide.
