Your Mobil Serv Lubricant Analysis report provides an easy to read, color-coded performance assessment with one of the following ratings:

Alert – Conditions exist that exceed acceptable limits or require corrective action. Steps should be taken to confirm and correct the condition.

Caution – Conditions are present that may require monitoring or diagnosis to minimize impact on equipment and lubricant performance.

Normal – Equipment, contamination, and lubricant conditions are within an acceptable range.

Sample comments are provided on the report to help identify potential problems, list possible causes, and recommend actions for follow-up.

Monitoring the trend

To assess your equipment condition:

Interpret your analysis results – Gain an understanding of your equipment’s operating conditions and its lubricated components. Limits applied to each sample can vary based on your asset's registered manufacturer, model, application, and lubricant-in-service.
Monitor the sample trend – Trend identification is important to understanding oil analysis results. You should include critical equipment and maintenance information (e.g., date sampled, hr/mi/km, makeup oil, etc.) with your sample submission. This data allows you to normalize the analysis trends to enhance your assessment.
Review the entire report – Proper condition assessment requires a complete review of the report. Changes in equipment condition typically coincide with the presence of contamination or changes in lubricant properties.
