Gear oils

Gearbox oil is essential to unlocking the range of performance your vehicle needs. Discover Castrol's gear oils from standard mineral to synthetic oils.

Gear oils

Industrial gearbox oil plays a pivotal role in sustaining the optimal performance of various machinery. Castrol offers a diverse range of gearbox oils and transmission fluids. This includes options for industrial gearbox oil, meeting every need from standard mineral-based to advanced synthetic formulations.

 

Understanding gear oil

Gear oil is a specialised lubricant that safeguards transmissions, transfer cases, and differentials across various industries, including automotive, aerospace, mining, and more. It typically possesses high viscosity and incorporates additives to withstand pressure and reduce wear.

 

When to change gear oil

Gearboxes and transmission systems constantly endure heat, wear, and friction. As fluids leak or degrade, they trigger gear grinding or slipping, indicating an imperative need for a prompt gear oil change.

 

Transmission oil vs. gear oil

As a general guideline, manual gearboxes utilise gear oil, while automatic transmissions employ transmission fluid. The distinction arises from their functions and designs. Gear oils possess higher viscosity, providing superior heat endurance in manual gearboxes. In contrast, transmission fluids are thinner and contain added detergents, catering to the intricate mechanisms of automatic transmissions.

 

FAQs

Q: Can I use transmission fluid in an industrial gearbox?

  • A: Occasionally. Some industrial gearboxes may accept transmission fluids. Always consult your Owner's Manual for the recommended fluid for your specific system.

Q: Can gear oil be utilised in an automatic transmission?

  • A: No. Gear oil's higher viscosity makes it unsuitable for automatic transmissions, potentially causing clogging in its components.

Q: Is there a universal rule for changing industrial gear oil?

  • A: No. The frequency of change depends on application and usage rates.

Q: What are the signs indicating the need for a gear oil change?

  • A: Detectable grinding or slipping sensations within the gearbox signal a necessary oil change.
