The NOACK Volatility Test determines the evaporation loss of lubricants in high-temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear, and emissions. A maximum of 15 percent evaporation loss is allowable to meet API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL Synthetic Motor Oil outperformed its nearest competitor by over 30 percent. The extremely low volatility of AMSOIL Synthetic Motor Oil allows it to maintain its superior protective and performance qualities throughout extended drain intervals, even when faced with severe operating temperatures. In addition, oil consumption and emissions are minimized and fuel efficiency is maximized. . . . . #amsoil #amsoilsynthetics #firstinsynthetics #reallygoodstuff #manandmachine (at Hyderabad) https://www.instagram.com/p/CIQaXQopSFU/?igshid=n1qbgk6ef7d4
