Determining Type of Lubrication System
What type of lubrication system is used in my engine?
To determine your engine's method of lubrication, please visit our Numerical Designation System page. By using your engine model number, you can determine the type of lubrication by the third number after the displacement. Either a 4 or 7 indicates a pressurized lubrication system. All other models utilize a variation of a splash type system.
