As a Harley owner for many years, I can attest to the importance of using primary oil specifically designed for my bike. While some may be tempted to use any type of oil in their Harley, the reality is that using the wrong type of oil can have detrimental effects on the engine and overall performance.

One of the main reasons why primary oil is necessary for Harley is because it is specifically formulated to meet the needs of the bike’s engine. Unlike regular motor oil, primary oil has additives that are essential for lubricating and protecting the primary drive and clutch components. These components are crucial for the smooth functioning of the bike and without proper lubrication, they can wear out quickly.

Moreover, primary oil also helps to prevent clutch slippage. Clutch slippage occurs when there is not enough friction between the clutch plates, causing a loss of power and acceleration. This can be a safety hazard as well as a nuisance while riding. Primary oil contains friction modifiers that ensure proper engagement of the clutch plates, resulting in improved performance and longevity.

Another reason why primary oil is necessary for Harley is because it helps to keep the engine cool. Harleys are known for their powerful engines, which generate a lot of heat while running. Primary oil has high thermal stability, meaning it can

My Buying Guide on Primary Oil for Harley

When it comes to maintaining your Harley Davidson motorcycle, one of the most important things to consider is the type of primary oil you use. The primary oil is responsible for lubricating the primary chain and clutch, ensuring smooth and efficient performance of your bike’s transmission. As a Harley owner myself, I have done extensive research and tried various primary oils to find the best one for my bike. In this buying guide, I will share my knowledge and experience to help you choose the right primary oil for your Harley.

Understanding Primary Oil

Before diving into the buying guide, it’s important to understand what primary oil is and why it’s crucial for your Harley. Primary oil is a specialized lubricant designed specifically for Harley Davidson motorcycles. It serves as both a lubricant and a cooling agent for the transmission system, minimizing friction between the clutch plates and preventing overheating. Choosing the right primary oil can significantly improve your bike’s performance and prolong its lifespan.

Consider Your Bike’s Model

Harley Davidson offers a wide range of models, each with its own specifications and requirements when it comes to primary oil. It’s essential to check your bike’s manual or consult with a mechanic to determine which type of primary oil is recommended for your specific model. Using an incorrect type of oil can cause damage to your bike’s transmission system, leading to costly repairs.

Viscosity Rating

Viscosity refers to how thick or thin the oil is at different temperatures. For Harleys, it’s recommended to use an SAE 20W-50 viscosity grade primary oil. This rating ensures that the oil maintains its viscosity even at high temperatures, providing proper lubrication and protection for your bike’s transmission.

Synthetic vs. Conventional

When it comes to choosing between synthetic or conventional primary oils, there are pros and cons to consider. Synthetic oils are made up of artificially produced molecules that offer better protection against extreme temperatures and have longer service intervals compared to conventional oils. However, they are also more expensive than conventional oils. On the other hand, conventional oils are derived from natural sources but may not provide as much protection as synthetic oils. Ultimately, it comes down to personal preference and budget.

Brand Reputation

There are numerous brands that offer primary oils specifically designed for Harleys. When choosing a brand, make sure they have a good reputation within the motorcycle community. You can do some research online or ask fellow Harley owners about their preferred brands.

Budget

The cost of primary oil may vary depending on factors such as brand, type (synthetic vs. conventional), and quantity needed for an oil change. It’s essential to set a budget beforehand so that you don’t overspend on an expensive brand or buy too much quantity than needed.

Final Thoughts

As a proud owner of a Harley Davidson motorcycle, I understand the importance of using high-quality products when it comes to maintenance. Choosing the right primary oil is crucial in ensuring optimal performance and longevity of your bike’s transmission system. By considering factors such as your bike’s model, viscosity rating, brand reputation, budget, etc., you can make an informed decision when purchasing primary oil for your Harley.
