Understanding the Importance of Oil Upgrades

Oil serves as the lifeblood of your Harley Davidson engine, lubricating vital components, reducing friction, and dissipating heat.

Over time, the oil’s effectiveness diminishes due to contaminants and breakdown.

Upgrading to high-quality oil ensures optimal engine performance and longevity.

Types of Harley Davidson Oil

Conventional Oil: Conventional oils are affordable and work well for regular riding conditions.

They provide basic protection but may require more frequent changes.

Synthetic Oil: Synthetic oils offer enhanced performance and durability, especially under extreme conditions.

They have a longer lifespan and provide better protection against engine wear.

Selecting the Right Oil Viscosity

When choosing oil for your Harley, it’s crucial to understand viscosity.

Viscosity refers to the oil’s thickness at different temperatures.

The Society of Automotive Engineers (SAE) viscosity grade is typically shown on oil containers with two numbers, such as 20W-50.

The first number (20W) indicates the oil’s flow at low temperatures, while the second (50) relates to its flow at higher temperatures.

For most Harley Davidson motorcycles, 20W-50 is recommended for its balance between cold-start protection and high-temperature stability.

Upgrading to Synthetic Oil

Making the switch to synthetic oil can significantly benefit your Harley Davidson.

Synthetic oils provide improved heat resistance, reduced engine friction, and better protection in extreme conditions.

While synthetic oils might cost more initially, their extended lifespan and superior performance justify the investment.

DIY Oil Change Steps

Here are the key steps:

Gather Supplies: You’ll need the appropriate oil, a new oil filter, a drain pan, a wrench, and gloves.

Warm Up the Engine: Run your motorcycle for a few minutes to warm the oil, making it easier to drain.

Drain the Oil: Place the drain pan beneath the bike, remove the drain plug, and let the oil drain completely.

Replace the Filter: Unscrew the old filter, apply a bit of new oil to the new filter’s gasket, and screw it in place.

Add New Oil: Refer to the oil capacity chart and pour in the recommended fresh oil.

Check the Level: Start the engine briefly, idle it, and check the oil level. Top up if necessary.

Dispose of Old Oil: Take your used oil to a recycling center.


Upgrading your Harley Davidson’s oil is crucial in maintaining its performance and longevity.

By selecting the right type and viscosity of oil and adhering to the recommended capacity, you’ll ensure your motorcycle runs smoothly for years to come.

Neglecting this aspect can lead to decreased engine efficiency, increased wear, and potential damage.

Furthermore, as a proud owner of a Harley Davidson, you understand the importance of meticulous care and maintenance.
