As a business owner or equipment operator, you know that keeping your machines running smoothly is crucial for your bottom line.

Regular maintenance is key to maximizing uptime and minimizing costs, but there is one aspect of equipment maintenance that is often overlooked - oil analysis.

Oil analysis can provide valuable insights into the condition of your equipment, allowing you to catch potential problems before they become major issues.

In this article, we'll explore the world of oil analysis and how it can benefit your equipment maintenance program.

What Is Oil Analysis?

Oil analysis tests are a diagnostic tool used to evaluate the condition of lubricants in machinery and equipment. The analysis involves testing a sample of the oil to determine its physical and chemical properties, as well as its level of contamination. Through routine oil analysis, technicians can gain insight into the condition of the equipment it is used in.

How an Oil Analysis Works

To perform oil analysis, a sample of the lubricant is sent to a lab for testing. The lab will test the sample for several properties, including:


Viscosity is a measure of how easily the oil flows. If the viscosity is too high, it can cause the equipment to work harder than necessary, leading to increased wear and tear. If the viscosity is too low, it can lead to inadequate lubrication, which can cause damage to the equipment.

Acid Number

The acid number is a measure of the acidity of the oil. If the acid number is too high, it can indicate the presence of contaminants or oxidation products in the oil. These contaminants can lead to corrosion and other damage to the equipment.

Base Number

The base number is a measure of the alkalinity of the oil. If the base number is too low, it can indicate that the oil is becoming acidic and losing its ability to neutralize acidic contaminants.

Water Content

Water is a common contaminant in lubricants. Excessive water can lead to corrosion and accelerated wear of the equipment.

Wear Metals

Wear metals are particles of metal that are a result of normal wear and tear in the equipment. By measuring the concentration of wear metals in the oil, technicians can gain insight into the condition of the equipment and identify potential problems.


Contaminants can come from a variety of sources, including dirt, dust, and other debris. By measuring the level of contaminants in the oil, technicians can identify potential sources of contamination and take corrective action.
