High viscosity index and premium fully synthetic base oils providing improved oxidation control compared to conventional oils, minimizing the formation of sludge and deposits and reducing oil thickening. This ensures the oil stays in grade for longer and extends both oil and engine life. Excellent anti-wear performance protects against engine wear and prolongs engine service life. Excellent temperature/viscosity characteristics ensure the protection of engine parts operating at both high and low temperatures. Low oil evaporation loss, a feature of the premium synthetic base oil, leads to improved fuel economy and reduces oil consumption, exhaust emissions and engine wear.
