How Do We Flag Engine Oils?

Fluid Life strives to increase your profitability and reliability by improving the ROI of your oil analysis program. One of the ways to improve the effectiveness of oil analysis is to have the best flagging limits; cutting down on nuisance flags and alerting problems.

Fluid Life offers a variety of options customized to help you maximize the benefit of your oil analysis program. Flagging describes the act of highlighting oil analysis results that indicate an abnormal condition and may require additional attention. Fluid Life applies three flags of increasing importance on every report, denoted by the terms Reportable, Unacceptable or Severe.

SAE Engine oils are flagged based on the kinematic viscosity measured at 100°C. We also monitor the kinematic viscosity measured at 40°C for abnormal trends or changes. Viscosity flags are applied to SAE engine oils taking into consideration the oil manufacturer’s product typical values, and whether or not the measured viscosity may indicate an abnormal condition. This practice minimizes nuisance flags, improves the quality of oil analysis alerting and is generally the most effective approach for condition monitoring.

Fluid Life also offers a secondary approach. Our team of equipment reliability professionals can perform a systematic review of your entire oil analysis program to optimize your flagging. Flagging can be based on SAE grade specifications, industry standards or using customer specific flag rules.
