Why OEM Preventive Maintenance Standards Exist (and Why They’re Ignored)

OEM preventive maintenance standards are not arbitrary. They are developed through years of field data, failure analysis, and component testing. Yet many compressors in the field operate outside these standards, often with costly consequences.

The Cost of Inconsistent Maintenance

Skipping service intervals, using non-approved fluids, or treating maintenance as optional introduces cumulative damage. Components may continue operating in the short term, masking internal wear that eventually leads to sudden failure.

Common examples include:

• Extended oil change intervals

• Inconsistent oil brands or grades

• Missed receiver tank filter service

• Partial fuel filtration maintenance

Each shortcut slightly increases risk. Together, they dramatically shorten equipment life. Reference the oil chart picture on this post.  While the picture references miles and not hours the same logic holds true for diesel air compressors.  The longer that oil goes without being changed the more metal particles are recirculating in the engine and causing additional wear on the components.  

Repeat Failures Are Rarely Random

When compressors experience repeat failures, the cause is frequently traced back to unresolved maintenance deficiencies rather than defective parts.

OEM standards exist to:

• Reduce repeat repairs

• Protect high-value components

• Improve reliability and uptime

• Ensure warranty compliance

Strict adherence to maintenance schedules and inspection procedures is the most effective way to avoid recurring issues and unexpected downtime.

A Smarter Long-Term Strategy

Whether operating new, remanufactured, or used equipment, preventive maintenance remains the most reliable strategy for long-term performance. Proper service preserves resale value, reduces total cost of ownership, and keeps equipment working when it is needed most.
