The World’s Source for Engine Oil Data

Testing & Quality Assurance

Institute of Materials’ Engine Oil Collection

An exacting collection process was followed by IOM trained collectors living in the countries from where collections are made, to ensure only the carefully selected brands, viscosity grades and service classifications are obtained. Custom collections follow this same quality process.

Ensuring Data Quality

IOM inspects each engine oil, then assigns it a blind-code sample ID to eliminate any brand perception biases. 

Samples are sent to pre-selected independent laboratories that specialize in lubricant testing and are:

  • Recognized leaders in the industry
  • ISO 9001 Quality Management System Certified
  • ISO/IEC 17025:2017 Accredited
  • Participants in the ASTM Proficiency Testing Program for engine oils  

IOM is ISO 9001:2015 Quality Management System Certified by ABS Quality Evaluations, Inc.
