How to Change the Engine Oil on a Harley Davidson Sportster

Model: Harley Davidson Sportster
Part: Engine oil

Video tutorial

To change the engine oil on a Harley Davidson Sportster, start by warming up the engine for a few minutes so that the oil becomes more fluid and easier to drain. Once the engine is off, position the bike on a stable surface, ideally on a stand, to ensure safety.

Locate the oil drain plug, usually found under the engine or along the lower frame. Using a spanner, loosen the drain plug, placing a container underneath to collect the used oil. Allow the old oil to drain completely, paying attention to any leaks or residues.

Once finished, reinsert the drain plug and tighten it properly to avoid future leaks. At this point, you can proceed to add the new oil. Pour fresh oil into the tank through the designated filler neck, ensuring you use the quantity and type of oil recommended by the manufacturer.

After adding the oil, restart the bike for a few minutes to allow the oil to circulate properly in the engine and check for any leaks under the bike.
