For more than 65 years, Southwest Research Institute (SwRI) has served as a technical partner to help lubricant, additive, and equipment manufacturers to improve automotive engine oil performance.
SwRI is the global leader in the field of standardized engine lubricant and driveline fluid testing for factory fill and service fill requirements. Facilities are available to evaluate lubricants against the American Petroleum Institute (API), SJ, SL, SM, SN, CH-4, CI-4, CI-4 PLUS and CJ-4 as well as International Lubricant Standardization and Approval Committee (ILSAC) GF-3, GF-4 and GF-5, and Cummins, Mack and John Deere requirements. For European ACEA lubricant specifications, SwRI has dynamometer and bench test methods to evaluate service-fill lubricants for gasoline and diesel engines. Gasoline and diesel engine lubricants are evaluated with respect to engine sludge, oxidation, component wear, oil consumption, piston deposits and fuel economy. New design engine components are also evaluated to determine acceptability with current day lubricants.
