What type of oil is 75W90?
Product Description Mobil Synthetic Gear Oil 75W-90 is a fully synthetic gear lubricant formulated from synthetic base oils and an advanced additive system. It is designed for use in many railway gearboxes and provides excellent load-carrying capability where extreme pressures and shock loading are expected.
What does 75W90 mean?
SAE 75W90 meaning The value before the “W” (W=winter suitability) indicates the flowability of the oil at cold temperatures. Gear oils with 75W remain flowable up to -40°C. The number “90” refers to the kinematic viscosity of the gear oil at 100 °C. The oil is not viscous. This comprises a range of 13.5 – 18.4 mm²/s.
What is 75W gear oil?
Mobil Gear Oil FE 75W is a high performance gear oil blended from high quality mineral base oils and an advanced additive system to meet Peugeot’s & Citroën’s specification. Mobil Gear Oil FE 75W is specially developed for PSA’s (Peugeot / Citroën) manual gearboxes with integrated differentials.
How do you read gear oil viscosity numbers?
Multigrade SAE gearbox oil grades include two numbers separated by a ‘W’ (75W140, for instance), with the initial number before the ‘W’ indicating performance at 0°C and the number after showing the lube’s performance at 100°C. As with monograde oils, the higher the number, the greater its viscosity.
What transmission fluid does my car need?
The type of transmission fluid you should use depends upon the make, model and year of your vehicle. For example, many General Motor cars will require a DEXRON fluid and Ford cars commonly specify a MERCON fluid. Always follow the vehicle manufacturer recommendation for proper fluid use and change interval.
What happens if gearbox oil is too thick?
If the oil is too thick or too thin excess wear will be caused on the synchronizer rings and they will not engage smoothly. Bearings need the right amount of oil flowing to and from them otherwise they suffer from overheating and premature wear.
