Motor oil types

Motor oil isn't "one-size-fits-all." Different vehicles and equipment require different motor oil types. For example, there is gasoline motor oil, European motor oil designed for the unique needs of European vehicles, diesel oil, racing oil and natural gas engine oil. Gasoline motor oil is made specifically for gas-powered engines, which are increasingly requiring lighter-viscosity oils formulated to maximize fuel economy. European motor oil is available in a wide range of viscosities and formulations designed to meet strict European automaker specifications. Diesel oil, meanwhile, is usually available in a higher viscosity, such as 15W-40, designed to deliver extra wear protection for powerful diesel engines. Racing oil is formulated to withstand the intense environment common to high-horsepower, high-torque racing engines. Since racing oil is changed so frequently, it doesn't contain the same level of detergency additives as gasoline motor oil. Natural gas engine oil is designed to combat issues specific to natural-gas engines, like valve recession and port blockage due to carbon deposits. Make sure to select the right type of motor oil for your engine.
