Gulf ARROW GT40 5W-40 Full Synthetic Engine Oil, 4L, for 4-Wheel Gasoline Vehicles

This is an environmentally friendly, high-performance fully synthetic engine oil with API SQ-level performance. By using an ultra-high viscosity index (PAO) with low evaporation, it achieves a high VI of over 200. Compared to typical commercial oils, it has a much more stable viscosity-temperature profile—higher at high temperatures and lower at low temperatures. It also minimizes oil consumption. It uses an unparalleled, high-performance VI improver, and its high shear stability, proven in races, maintains an adequate oil film even at high temperatures, helping to protect the engine and reduce oil consumption under severe conditions. This VI improver with a well-balanced molecular weight also contributes to excellent low-temperature starting, ensuring quick oil distribution to key engine parts immediately after starting in cold weather. Furthermore, the ester base provides excellent oiliness and lubricity, and the oil modifier organic molybdenum is blended to reduce friction and improve fuel economy. This results in smooth, quiet engine rotation, as well as quick response and torque to the accelerator. In addition, the antioxidant boost extends engine life, making this engine oil ideal for motorsports, where engine performance is at its peak. Of course, it's turbo compatible. Recommended for European vehicles as well. Gulf is a global oil brand with over 100 years of history, founded in Texas, USA in 1901.
