Everything Needed for the Engine Oil Change
AMSOIL 20W-50 V-Twin Oil
Each kit contains either four or five quarts of AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil, depending on the kit.
It is formulated for air-cooled V-twin heat, viscosity stability and motorcycle service.
AMSOIL Motorcycle Oil Filter
Each kit contains one AMSOIL motorcycle oil filter. The black and chrome versions provide the same basic kit choice with a different visible finish.
Drain-Plug O-Ring
Each kit includes one replacement drain-plug O-ring. Replace the seal rather than automatically reusing an old, flattened or damaged O-ring.
Black Filter or Chrome Filter?
The black and chrome kits are separated so the visible oil filter can match the motorcycle. Choose the finish you prefer after confirming the correct oil quantity and filter application.
Black Oil Filter
The black filter generally blends with blacked-out engines, dark exhaust systems and motorcycles with less chrome.
Choose HDBK for the four-quart package or HDMB for the five-quart package.
Chrome Oil Filter
The chrome filter works well on motorcycles where the filter is visible beside chrome engine covers, exhaust or other bright finishes.
Choose HDCK for the four-quart package or HDMC for the five-quart package.
How to Find the Correct Kit
Select the Exact Model Year
Do not choose the nearest year and assume the engine, capacity or filter remained unchanged.
Select the Full Harley Model
Street Glide, Road Glide, Road King, Softail, Sportster, Trike and CVO applications can use different capacities and filters.
Confirm the Engine and Displacement
Twin Cam, Milwaukee-Eight, Evolution and Revolution Max motorcycles do not all share the same oil-change requirements.
Use the Listed Oil Change Kit
The AMSOIL motorcycle lookup will display the correct kit where an oil-change kit is available for the selected motorcycle.
Choose Black or Chrome
Once the quantity and filter application are confirmed, select the filter finish that best matches the motorcycle.
Do Not Guess Based Only on Engine Family
Four-quart kits are generally listed for most 1999–2016 Harley-Davidson applications. Five-quart kits are generally listed for most 2016–present applications. That does not mean every bike built in a particular year uses the same quantity.
Four-Quart Kits
HDBK-EA and HDCK-EA are intended for most listed 1999–2016 Harley-Davidson motorcycles.
These kits are commonly associated with many Twin Cam-era applications, but the exact motorcycle lookup remains the deciding source.
Five-Quart Kits
HDMB-EA and HDMC-EA are intended for most listed 2016–present Harley-Davidson motorcycles.
These kits are commonly associated with many Milwaukee-Eight-era applications, but there can be model and year differences.
Harley Oil Change Checklist
- Confirm the exact motorcycle and correct AMSOIL kit before draining the oil.
- Warm the engine enough to help the oil drain, while avoiding burns from hot oil, exhaust and engine components.
- Verify the engine oil drain plug. Do not accidentally remove the transmission or primary drain plug.
- Inspect the drain plug, threads and sealing surface before installing the new O-ring.
- Lubricate the new oil-filter gasket with clean engine oil before installing the filter.
- Tighten the filter and drain plug according to the proper service information for the motorcycle.
- Start the engine and inspect for leaks before the motorcycle is returned to service.
- Check the final engine oil level using the procedure specified for the exact Harley-Davidson model.
Protection for Air-Cooled V-Twin Service
Extreme-Heat Resistance
Air-cooled V-twin engines can expose oil to high temperatures during summer riding, slow traffic, rallies, parades, heavy loading and modified-engine operation.
Viscosity Stability
The oil must resist thinning and viscosity loss while protecting heavily loaded components under demanding motorcycle operation.
Engine Cleanliness
Oxidation resistance and deposit control help protect piston rings, maintain compression and keep hot internal surfaces cleaner.
Three-Compartment Capability
AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil can also be used in the primary and transmission where recommended, although the oil-change kits contain only enough product for the engine service.

Common Questions
Which AMSOIL Harley oil change kit do I need?
Use the AMSOIL motorcycle lookup with the exact year, model and engine. The lookup will identify the correct available kit. Four-quart kits generally cover most listed 1999–2016 applications, while five-quart kits generally cover most listed 2016–present applications.
What is included in the AMSOIL Harley oil change kit?
Each kit includes four or five quarts of AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil, one AMSOIL motorcycle oil filter and one drain-plug O-ring.
Does the kit include primary fluid?
No. The kit is packaged for the engine oil change. Primary fluid must be ordered separately when servicing the primary chaincase.
Does the kit include transmission fluid?
No. Transmission fluid must be ordered separately when servicing the transmission.
What is the difference between HDBK and HDCK?
Both contain four quarts of AMSOIL 20W-50 V-Twin Motorcycle Oil and a drain-plug O-ring. HDBK includes a black oil filter. HDCK includes a chrome oil filter.
What is the difference between HDMB and HDMC?
Both contain five quarts of AMSOIL 20W-50 V-Twin Motorcycle Oil and a drain-plug O-ring. HDMB includes a black oil filter. HDMC includes a chrome oil filter.
Is the black or chrome AMSOIL filter better?
Choose the finish that suits the motorcycle after confirming the correct filter and kit application. The practical buying difference between these paired kits is the visible filter finish.
Can AMSOIL 20W-50 be used in all three Harley compartments?
Yes, on most Harley-Davidson motorcycles for which AMSOIL recommends it. It can serve as engine oil, primary lubricant and transmission lubricant. The oil-change kit itself only contains enough oil for the engine service.
Does the kit include a new drain-plug O-ring?
Yes. Each of the four AMSOIL Harley oil change kits includes one drain-plug O-ring.
Should every quart in the kit be poured into the motorcycle?
Follow the proper filling and oil-level procedure for the exact motorcycle. The packaged quantity does not replace the final oil-level check. Do not overfill the oil tank simply to empty every bottle.
How often should Harley-Davidson engine oil be changed?
Follow the applicable motorcycle service schedule and lubricant recommendation. Severe heat, repeated short trips, stop-and-go operation, engine modifications, racing and contamination may require shorter service intervals.

Enter the exact year and model in the AMSOIL motorcycle lookup, confirm the required four-quart or five-quart kit, then choose a black or chrome oil filter.
