Abstract
A new 0W-20 gasoline engine oil was developed to improve fuel economy over ILSAC GF-2 5W-20 gasoline engine oils and to meet ILSAC GF-3 requirements. The main improvements made were to viscosity and friction modifiers. Viscosity at 80°C was adjusted to obtain better fuel economy than with 5W-20 oil in the Japanese 10-15 mode test. Therefore, low-temperature viscosity decreased to 0W and high-temperature high-shear viscosity exceeds 2.6 mPa?s. Friction modifiers and other additives were investigated to find the lowest friction characteristics. The resulting formulation shows more than a 2.0% fuel economy gain in the Japanese 10-15 mode test and the new oil has been certified as meeting ILSAC GF-3 requirements.
