Cat® S·O·S℠ Services – Lower Maintenance Costs, Greater Reliability
Keep your equipment in top condition while reducing ownership and operating costs. With the Cat® S·O·S℠ oil and coolant analysis programme, you’ll know exactly what’s happening inside your machine — enabling smarter maintenance decisions and longer component life.
Developed by Caterpillar engineers and chemists, S·O·S tests detect early signs of wear, contamination, or imbalance before costly repairs are needed. Regular sampling helps prevent breakdowns, reduce downtime, and protect your machine’s value.

Whether you manage maintenance yourself or partner with Avesco, S·O·S℠ Services form a vital part of a proactive equipment care strategy — ensuring maximum performance, reliability, and return on investment.
Quick results - fast actions.
You will receive test results and expert recommendations within 48 hours of the samples arriving at the laboratory. The results are presented in a clear and easy-to-understand report, and any critical findings are communicated immediately. Recommendations based on alert levels help prioritize maintenance, optimize service schedules, and extend component service life.
S·O·S services are part of a proactive maintenance approach, where machine condition is systematically monitored using analyses, inspections, and service data. Combined with Avesco’s preventive maintenance and genuine Cat parts, they ensure the efficiency, reliability, and value retention of your equipment.
The way S·O·S analysis results are accessed is changing
Caterpillar is unifying its service channels, and as a result the SOS Web website will be discontinued during 2026.
In the future, SOS sample results will be available in the VisionLink fleet management system.
At the same time, the delivery method of the results will also change: the automatically emailed PDF report will be replaced by VisionLink notifications, which you can easily configure yourself.
