FAQ:

What is 75W-140 gear oil used for?

• Lucas 75W-140 gear oil is specifically designed for use in heavy-duty applications such as differentials and gearboxes, especially in vehicles subjected to high temperatures or heavy loads. It offers superior protection and lubrication, ensuring optimal performance and reduced wear in extreme conditions.

What does the 140 mean on gear oil?

• The number '140' in 75W-140 gear oil refers to the oil's viscosity at higher temperatures. In the Society of Automotive Engineers (SAE) viscosity grading system, the higher number indicates the oil's viscosity when operating at elevated temperatures. A 75W-140 oil provides better protection and remains thicker than lower-viscosity oils under high temperatures and loads.

Can I use 75W-140 instead of 75W-90?

• While both 75W-140 and 75W-90 gear oils have similar viscosity ratings at cold temperatures (75W), the 140 and 90 respectively denote the oil's viscosity at higher temperatures. It's generally recommended to adhere to the manufacturer's specifications for your vehicle. Using 75W-140 instead of 75W-90 could provide added protection under extreme conditions, but it's essential to consult your vehicle's manual for compatibility and recommendations.

What is the meaning of SAE 75W-140?

• The SAE 75W-140 designation denotes the oil's viscosity rating under different operating temperatures. The '75W' signifies the oil's viscosity in colder conditions, ensuring smoother cold starts. The '140' indicates its viscosity at higher temperatures, offering enhanced protection and stability in extreme heat or heavy-duty applications.
