What kind of oil do you put in a Harley Davidson shovelhead?
Using Harley-Davidson’s Screamin’ Eagle oil is recommended. Use 4 qts. of 25W-50 weight oil for engines that have had minor or major modifications to either the valvetrain or pistons. The 50-weight oil is also recommended for stock Shovelhead engines in cold climates or in high altitudes.
Why is the oil coming out of my Shovelhead?
