Great all-weather viscosity grade for gasoline engines in cars and
light trucks that are driven on the street on a daily basis. More power
and economy while providing thicker bearing oil films at operating
temperature than a petroleum 10W-40. 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.
