Harley Oil Element
Engine Oil Change at Our Shop
Our shop is equipped with a bike lift suitable for Harleys. The engine oil change process begins immediately if the engine is hot upon arrival.
The duration varies depending on the bike model and oil used, but typically it takes about 1 to 1.5 hours to change all three types: engine, mission, and primer oils.
Please come with some time to spare, as we prefer to let the oil drain for a while after extraction.
