Low-Volatility Motor Oil Helps Unlock Your Vehicle’s Performance John Baker | May 26, 2015 3:16:00 PM Modern engines, particularly those equipped with performance-enhancing technologies like direct fuel injection and turbochargers, generate increased heat compared to their predecessors. At elevated temperatures, such as during severe service or when driving in hot summer weather, the oil’s lighter-weight molecules can volatilize, or literally “boil off.” The more volatile a lubricant is, the lower the temperature at which the lubricant will begin to evaporate. The more it evaporates, the less oil is left to protect equipment and the faster a user must replace the lost oil. You may have experienced this phenomenon by owning an automobile that “uses” motor oil in irregular intervals. Volatility affects more than the rate of oil consumption. When light elements in oil evaporate from heat, the oil’s viscosity increases. This thicker oil forces the engine to work harder, resultin
