10W30: Best all-weather viscosity grade for gasoline engines in cars and light trucks that are driven on the street on a daily basis. Reduces turbo lag and provides more power and economy while providing thicker bearing oil films at operating temperature than a petroleum 10W-40. Best all-round, synthetic oil for stock or slightly modified engines in high-performance cars that are street-driven. Best choice to replace a 5W-30 or 10W-30, petroleum-based or other-brand synthetic oil if maximum durability is preferred. Acceptable for engines that are occasionally operated in extreme cold weather.
