What does 85w90 mean?
The value before the “W” (W=winter suitability) indicates the flowability of the oil at cold temperatures. Transmission oils with 85W remain flowable up to -12 °C. The number “90” refers to the kinematic viscosity of the gear oil at 100 °C. This comprises a range of 13.5 – 18.4 mm²/s.
What happens if gear oil is too thin?
When designing the tooth profile of the gears, consideration is given to the weight of the oil. An oil that is too thin for a tooth design will cause the gears to make metal on metal contact, causing premature wear. Too thick and excess drag is caused, reducing economy and sapping power.
