Application Guide

Step-by-step instructions for optimal use of Gear Oil GL-5 80W-90 in Automotive applications.

1

Preparation

Ensure the application surface is clean, dry, and free from contaminants. Remove any existing lubricant residues using appropriate cleaning agents. For Hypoid differentials applications, verify equipment is at operating temperature.

2

Application Method

Apply Gear Oil GL-5 80W-90 using standard industrial equipment. For grease products, use automatic lubrication systems or manual grease guns. For liquid lubricants, ensure proper filling procedures and avoid contamination during transfer.

3

Recommended Dosage

Follow OEM recommendations for fill quantities. For Automotive applications, typical re-lubrication intervals range from 1,000 to 5,000 operating hours depending on conditions. Monitor performance and adjust intervals based on actual operating parameters.

4

Performance Monitoring

Regularly inspect lubricant condition and equipment performance. Check for signs of degradation, contamination, or unusual wear. Schedule oil analysis every 6 months for critical applications to optimize maintenance intervals.

Storage Recommendations

  • Store in a cool, dry place between 5°C and 35°C
  • Keep containers sealed when not in use
  • Avoid direct sunlight and moisture exposure
  • Shelf life: 5 years from manufacture date when stored properly

Safety Information

  • Refer to Safety Data Sheet (SDS) before use
  • Use appropriate PPE: gloves and safety glasses
  • Ensure adequate ventilation in application area
  • Dispose of used lubricant according to local regulations
