Red Line 10W30 Synthetic Motor Oil

We use Red Line Synthetic Oil in all of our BMW PRO3 and Spec Miata race cars, as well as our customers' race cars. 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 10W40. Best choice to replace a 5W30 or 10W30, petroleum-based or other-brand synthetic oil if maximum durability is preferred. Acceptable for engines that are occasionally operated in extreme cold weather.
