Using CFR engines, SwRI measures the antiknock characteristics of finished gasolines and determines motor octane numbers.
 

The Scanning Brookfield measures gelation index of engine oils by continuously lowering the test temperature while recording.
 

Vacuum distillation test for biodiesel samples.

Extensive capabilities are available at Southwest Research Institute (SwRI) to conduct ASTM International, ISO, EN, and other standardized test methods.
