Variability in Oil Analysis Results Two consecutive samples, at normal sampling intervals from the same machine, are never expected to have exactly the same results, but occasionally the second set of results appears to have either changed by more than a normal amount, or possibly have shifted in a counter-intuitive direction (i.e. gotten better without…

What is in these oils, and which one is better?

What is in these oils, and which one is better? A relatively common request to an oil analysis lab is to identify the ingredients in samples of new lubricants and/or determine which lubricant will perform better. While this is possible with laboratory testing, it requires vastly different testing than is routinely performed. The predominant analysis…

Oil Analysis Test Frequency Guidelines

Oil Analysis Test Frequency Guidelines There is no universal formula for determining oil sampling frequency, but most experts consider monthly sampling to be optimum for critical machinery.  However, when making this decision, it is important to consider the objectives of the oil analysis program. If the only objective is to perform condition-based oil changes, the…

Oil Analysis Trending vs. Alarm Limits

Oil Analysis Trending vs. Alarm Limits Many static alarm limits are based on statistical analysis of a common grouping of machines under similar operating conditions. As long as machine is operated under similar conditions (load, speed, temperature, ambient environment) for a similar sampling and drain interval, the limits may have merit.
