Benefit - Proven 2% improvement in fuel efficiency over GF-4 oil
Sustina utilizes Nippon Oil's own W BASE base oil technology to maintain an extremely stable oil viscosity over a wide temperature range.
This technology allows SUSTINA to be very fluid at cold temperatures, reducing internal engine drag and improving fuel economy up to 2% when compared to currently available fuel conserving GF-4 oils of the same viscosity.
W BASE Technology- High Viscosity Index base oil
Typical synthetic base oil is made up of carbon and hydrogen ring-shaped molecular structures. As these structures move, they tend to collide and intertwine, slowing their movement especially at low temperatures, resulting in very high cold start viscosity.
W BASE technology realigns the carbon and hydrogen structure into a relatively straight line, allowing free movement of the molecules even at low temperatures, providing lower engine drag and improved fuel efficiency.
