Frequently Asked Questions

LUBELINE™ Knowledge Base

What’s the difference between industrial oils and greases?

Industrial oils are liquid lubricants used in systems like hydraulics, gearboxes, and compressors, where efficient flow and heat dissipation are essential. Greases are thicker, combining oils with a thickening agent, making them ideal for bearings, joints, and slow-moving machinery where re-lubrication is less frequent or where oil would leak out.

How do I know which lubricant is right for my equipment?

  • Selecting the correct lubricant depends on:
  • Type of machinery
  • Operating temperature and load
  • Speed and duty cycle
  • Environmental conditions (dust, water, heat, etc.)

Our LUBELINE™ technical team can recommend the right oil or grease based on OEM specifications and your operating conditions.

How often should industrial equipment be lubricated?

Lubrication intervals vary:

  • Some systems require daily or weekly checks
  • Others may only need service every few months

The best approach is to follow OEM guidelines and use tools such as oil analysis to monitor lubricant condition and extend equipment life.

Can I mix different brands or types of lubricants?

In most cases, mixing lubricants is not recommended. Chemical incompatibilities may reduce performance and equipment protection. Always:

  • Check product data sheets
  • Consult a lubrication specialist
  • Flush the system before switching products

What are the signs of lubricant failure?

Warning signs include:

  • Excessive noise or vibration
  • Rising operating temperatures
  • Visible wear or scoring on components
  • Oil leaks, discoloration, or thickening

Regular inspections and oil analysis can detect early signs of failure and prevent costly downtime.

What should I consider when purchasing a lubricant?

When buying lubricants, consider:

  • Specifications – Industry standards (API, ACEA, ISO)
  • OEM Approvals – Certified by equipment manufacturers
  • Recommendations – Advisory guidelines without formal testing

While house-brand or blended oils may meet some specs, they often lack full OEM approvals. Choosing approved, high-quality lubricants ensures:

  • Better protection and performance
  • Longer equipment life
  • Reduced risk of damage and downtime
