The Cost of Neglecting Oil Maintenance

Failing to maintain clean gearbox and hydraulic oil leads to far more than dirty fluid—it leads to lost time, money, and critical system failure. Without a proper oil change-out program, operations face serious consequences, including:

The Problems

  • System faults and mechanical failures

  • Unplanned equipment downtime

  • Shortened fluid and component life

  • Increased maintenance and repair costs

  • Lost revenue and reduced productivity

The Warning Signs

  • Accelerated mechanical wear

  • Corroded metal surfaces

  • Loss of lubricity

  • Additive breakdown

  • Viscosity variance

  • Bearing failure

The Root Cause

Contaminated oil is the #1 cause of component failure in hydraulic and lubrication systems. Studies show that 70–75% of failures are linked to surface degradation from poor fluid quality.

  • Water, particulate, and unfiltered oil are major contributors to wear

  • Even new oil can introduce contaminants if not filtered properly

  • Contamination leads to abrasive wear, corrosion, electrical conductivity issues, and early system failure

  • Meeting ISO 4406 cleanliness codes before introducing oil into a system is essential

Maintaining clean, dry oil can extend component and equipment life by up to —while preventing the costly failures that come from ignoring fluid health.
