Introduction

Your Harley Davidson V-Twin Cam engine needs the right oil to perform at its best and last for a long time. The 20W-50 oil is recommended by Harley Davidson for its V-Twin Cam engines, and using the best quality oil can significantly impact your engine’s performance, efficiency, and longevity. To help you make the right choice, we have compiled a list of the top 10 best oils for Harley Davidson V-Twin Cam 20W-50 engines.

Why 20W-50 Oil?

20W-50 oil is a multigrade oil that provides excellent protection and performance across a wide range of temperatures. The “20W” in the name represents its viscosity at low temperatures, while the “50” indicates its viscosity at high temperatures. This combination ensures that the oil flows smoothly and provides adequate protection against wear, friction, and oxidation in both cold and hot weather conditions.

Harley Davidson recommends using 20W-50 oil in its V-Twin Cam engines because it offers the right balance between protection and performance. It ensures that the engine remains cool, reduces friction, and provides excellent wear protection, making it the ideal choice for this type of engine.

Synthetic vs. Conventional Oil

When it comes to choosing the best oil for your V-Twin Cam engine, you have two main options: synthetic and conventional oils. Both types have their advantages and disadvantages, and it’s essential to understand the differences before making a decision.

Synthetic Oil

Synthetic oil is a laboratory-created lubricant that offers superior performance compared to conventional oils. It has a higher viscosity index, lower friction, and a lower Noack value, which means it provides better protection against wear, friction, and oxidation. Synthetic oil also performs well in extreme temperatures, ensuring that your engine remains cool even in hot weather conditions.

The main disadvantage of synthetic oil is its higher cost compared to conventional oils. However, considering the benefits it offers in terms of engine protection and performance, many riders find it to be a worthwhile investment.

Conventional Oil

Conventional oil is a petroleum-based lubricant that has been used in engines for many years. While it offers adequate protection and performance, it doesn’t perform as well as synthetic oil in extreme temperatures and may not provide the same level of wear protection.

Conventional oil is usually cheaper than synthetic oil, making it an attractive option for riders on a budget. However, it’s essential to weigh the cost savings against the potential risks to your engine’s performance and longevity.
