"About 500 blends a month are created at the center. Each blend consists of 15 to 20 different components on average, and by volume breaks down as 75-85 percent base stocks and 15-25 percent wear additives and friction modifiers. Real-world testing begins in the motor shop, where blends are run in cradled engines to obtain high-speed, high-load and high-temperature performance numbers. After testing, engines are disassembled and digital microscopes are used to inspect part surfaces for wear.
In another area of the center, vehicles of every make and model are strapped to dynamometers to test oil blends, sometimes against competitive brands. Cycles can be custom-programmed to generate data for high speeds, stop-and-go traffic, long durations, or any combination of driving conditions."
