Lab Services


Lubricants are commonly referred to as the “lifeblood” of machines and equipment.

Just as medical labs analyze key indicators within our blood, oil analysis labs analyze key indicators within in-service oils. When we learn how to interpret this information, we can correct problems in the early stages of development before there is permanent damage to the equipment.

An assessment of the oil condition reveals whether the system oil should be changed or if it is fit for further service. In addition, it lowers expenses by optimizing the oil change intervals. The extended service intervals are determined by the condition monitoring; when the oil condition and contamination is routinely monitored, system wear can be minimized. Detection of ingress of contaminants from the manufacturing environment, including process contaminants, dirt, and water provides warnings as to the appropriate timing for filtration.

Oil analysis can detect subtle changes in the levels of wear metals present in the system oil; failures due to worn components can be avoided before the components are beyond specification.

The Benefits of Oil Analysis:

  • Minimized Unscheduled Downtime
  • Improved Maintenance Scheduling
  • Improved Equipment Reliability
  • Reduced Maintenance Costs
  • Minimized Installation Errors
  • Extended Service and Maintenance Intervals
  • Reduced Oil Disposal (Decreased Carbon Footprint)

The Hydrotex Oil Analysis Seminar covers the following topics:

  • The Basics of Oil Analysis
  • How Oil Analysis Works
  • Customer Support
  • Evaluation Process
  • Sampling Methods
  • Testing
  • How to Read a Report


Fuel analysis is a critical component of Clean Diesel Fuel Management. Fuel analysis can be used as a predictive tool to determine any potential performance issues or sources of contamination before impacting your fleet. Fuel analysis guides recommendations for specific fuel treatment with Hydrotex fuel improvers to optimize fuel usage and fleet performance during both summer conditions and harsher winter conditions.
