Compressor Oil Analysis: Critical Tests to Prevent Equipment Failure | Eurofins TestOil

Compressor Oil Analysis: Critical Tests to Prevent Equipment Failure | Eurofins TestOil
Industrial compressors operate under demanding thermal and mechanical conditions that accelerate lubricant degradation and increase the risk of unexpected equipment failure. For reliability engineers, compressor oil analysis provides critical diagnostic information about lubricant condition, contamination, and component wear before performance deteriorates.                 Unlike many other industrial lubrication systems, compressors expose lubricants to repeated compression cycles,…

Plain (Babbitt) Bearing Oil Analysis: Recommended Tests for Reliable Performance | Eurofins TestOil

Plain (Babbitt) Bearing Oil Analysis: Recommended Tests for Reliable Performance | Eurofins TestOil
Plain/Babbitt bearings are engineered to operate under demanding loads while maintaining a protective hydrodynamic oil film. Their soft, conformable bearing surfaces accommodate minor shaft misalignment and embed small contaminants, but these advantages also make them vulnerable to lubrication deficiencies.                 For reliability engineers, the challenge is distinguishing normal bearing behavior from early-stage deterioration before it…

The Business Case for Used Oil Analysis in Transit Operations | Eurofins TestOil

The Business Case for Used Oil Analysis in Transit Operations | Eurofins TestOil
For public transit agencies and private transportation operators, maintenance performance has financial implications extending well beyond repair costs. Unplanned vehicle downtime affects service reliability, fleet utilization, labor productivity and, ultimately, operating margins. Used oil analysis provides a measurable opportunity to manage these risks through condition-based maintenance. Moving Beyond Scheduled Maintenance                 Traditional preventive maintenance programs…

Zinc in Locomotive Engine Oil: Anti-Wear Protection and Bearing Risks | Eurofins TestOil

Zinc in Locomotive Engine Oil: Anti-Wear Protection and Bearing Risks | Eurofins TestOil
Zinc-based anti-wear additives have long been key to protecting heavily loaded engine components. However, in certain locomotive engines, the chemistry that protects one component can create compatibility concerns for another—particularly silver-plated bearings. Understanding this distinction is essential when selecting lubricants and interpreting used oil analysis results. The Zinc-Silver Compatibility Challenge                 Zinc dialkyldithiophosphate (ZDDP) is…

Fuel Contamination in Bus Engine Oil and How It Affects Engine Health | Eurofins TestOil

Fuel Contamination in Bus Engine Oil and How It Affects Engine Health | Eurofins TestOil
Fuel contamination can be an important indicator of both lubricant condition and developing mechanical problems in bus engines. When unburned fuel enters the crankcase and mixes with the engine oil, it changes the lubricant’s physical properties and can compromise its ability to protect critical components.                 This contamination lowers both oil viscosity and flash point.…

Glycol in Bus Engine Oil: An Early Warning Sign of Coolant Leaks | Eurofins TestOil

Glycol in Bus Engine Oil: An Early Warning Sign of Coolant Leaks | Eurofins TestOil
For transit fleets, coolant entering engine oil can turn a relatively manageable maintenance issue into a major engine failure. Detecting glycol in the lubricant provides an important early warning that allows maintenance teams to investigate the source before extensive damage occurs.                 Glycol contamination usually points to an internal coolant leak involving components such as…
