Suggested timing for sampling: 

  • Oil Sampling
    • The lubrication system cools and lubricates your generator engine and equipment. Recommended interval for oil sampling is every 250 hours or 12 months, whichever comes first. 
  • Coolant Sampling
    • Changes in coolant quality or depletion of essential elements decrease the protection of your generator's engine coolant system.
    • Recommended interval for coolant sampling is every 12 months.
  • Fuel Sampling
    • Analyze fuel samples for water and microbial contamination with lab testing methods to help prevent poor fuel quality which can result in your generator not starting when it's needed most. Recommended interval for fuel sampling is every 12 months.

The timing of oil sampling for power generators depends on various factors, including the type of generator, the operating conditions, and the manufacturer's recommendations. However, there are some general guidelines that can be followed:

  1. Newly Commissioned Equipment
    • Oil sampling is often recommended shortly after commissioning a new generator to establish a baseline for future comparisons.
  2. Regular Maintenance Intervals:
    • Routine oil analysis can identify adverse conditions in the lube oil that affect performance and ultimately help protect your machine’s operation and lifespan. Routine oil sampling is typically conducted during scheduled maintenance intervals. The frequency of these intervals can vary based on the generator type, usage patterns, and manufacturer recommendations. It could be every 3 months, 6 months, or annually.
  3. Critical Operating Conditions:
    • Oil sampling should be performed more frequently during critical operating conditions or when the generator is subjected to unusual loads, high temperatures, or other stressful conditions. The lube oil health is the essence of its success.
  4. After Significant Events:
    • Sampling may be necessary after significant events such as power outages, overheating incidents, or other abnormal operating conditions.
  5. Changes in Operating Conditions:
    • If there are changes in operating conditions, such as increased load or extended operation at high temperatures, it may be advisable to adjust the frequency of oil sampling accordingly.
  6. Condition Monitoring Systems:
    • Some generators are equipped with condition monitoring systems that continuously assess the condition of the oil and other components. In such cases, sampling may be triggered automatically based on the system's analysis.
