Fuel analysis in the Fuels and Lubricants Research Division at Southwest Research Institute (SwRI) offers virtually every standard industry test, including ASTM, UOP, SAE, and federal tests to evaluate fuel, lubricant, and functional fluid quality. CFR octane and cetane engines measure antiknock characteristics of finished gasolines and the ignition quality of diesel fuels.
