Doubling Oil's Useful Life
To reduce oil use while properly maintaining its heavy equipment known as ‘yellow iron,’ Republic Services’ West California office looked at reducing the number of oil changes by using synthetic oil blends. Synthetic oil lubricants cling better to the equipment components than mineral oils do, dispersing heat more efficiently and extending the oil’s useful life. Using these superior oil blends reduces the amount of oil used, and decreases the amount of oil and filters that need to be disposed of.

Within 7 months of beginning its program, Republic Services had tested and extended drain intervals on approximately 60 machines with the following outcomes:
  • Engine oil filters are replaced every 500 hours instead of 250 hours
  • Hydraulic oil filters are replaced every 4,000 hours instead of 2,000 hours
  • Transmission oils get changed every 2,000 hours instead of 1,000 hours
The program is beneficial for the environment because there is less overall waste, and creates cost-efficiencies through reduced labor and parts.
