| Advanced Lubricant Technology (Synthetic Lubricants) | | Low Friction Engine & Drive Train Lubricants commonly known as synthetic engine oil and synthetic transmission & drive train lubricants, these synthetic products can improve fuel efficiency by as much as 3% by reducing friction between parts. Synthetic lubricants are designed to withstand the extreme pressures of the engine, transmission and drive train better than traditional oils. In addition to increased fuel efficiency, synthetic engine lubricants reduce wear and increase maintenance intervals. |
