Engine Oil Testing Services & Used Oil Analysis (UOA)

Providing ISO/IEC 17025 accredited Engine Oil Testing Services for predictive maintenance, tribology, and fleet reliability.

Proactive Condition Monitoring & Tribology

AGT Labs provides professional Engine Oil Testing Services to extend equipment life and optimize maintenance schedules. Our Houston-based laboratory specializes in comprehensive Used Oil Analysis (UOA), detecting early signs of wear, contamination, and additive depletion in diesel, natural gas, and gasoline engines.

Our Engine Oil Testing Services support fleet managers, industrial plants, and marine operators with accredited technical data. By monitoring critical parameters like viscosity, base number (TBN), and wear metals, we help you identify component failures before they occur, reducing unscheduled downtime and repair costs.

Value for Stakeholders: Fleet Managers extending drain intervals through our Engine Oil Testing Services, Reliability Engineers preventing catastrophic failures, and Maintenance Teams reducing Total Cost of Ownership (TCO).

Containers & Handling

  • Use clean, dry plastic bottles provided in our sampling kits.
  • Sample from a live zone (e.g., after the pump, before the filter) while the engine is warm.
  • Avoid sampling from the drain plug bottom to prevent sludge bias.

Transport & Logistics

  • Label with Equipment ID, Hours on Oil, and Oil Brand/Grade.
  • Ship immediately to our Houston lab for timely trend analysis.
  • Consistent sampling intervals are key for effective condition monitoring.

Frequently Asked Questions

Why track Total Base Number (TBN) in engine oil?
TBN measures the oil's remaining alkaline reserve to neutralize acidic combustion byproducts. In our Engine Oil Testing Services, tracking TBN helps determine the optimal oil drain interval, preventing corrosion and sludge buildup.
What do high Iron and Aluminum levels indicate?
Elevated Iron typically suggests cylinder liner or crankshaft wear, while Aluminum often indicates piston wear. Our analysis identifies these wear metals early, allowing you to schedule repairs before catastrophic failure.
How does fuel dilution affect engine oil?
Fuel dilution lowers oil viscosity, reducing its ability to lubricate and protect moving parts. Our Engine Oil Testing Services detect fuel leaks from injectors or pumps, preventing accelerated wear and potential fires.
Can you detect coolant leaks in oil?
Yes, we detect coolant contamination by analyzing for Sodium and Potassium (common coolant additives) and checking for Glycol. Coolant in oil forms sludge and acids, rapidly destroying bearings and filters.
