Who Makes Harley Davidson Oil? Things You Mightn’t Know!

Harley Davidson has not only rolled out new engines in the market but also delivered oil for their bikes. And their oil types have top-notch features that are not common in the USA. It is possible only because of Sunoco, the company that makes Harley Davidson oil. 

Just because SUNOCO is a manufacturer based in the USA does not mean that they make their oil there. Instead, they export from different countries. What are these, and how is the oil different from others? Let’s get to know the secrets! 

Who Makes Oil For Harley Davidson?

SUNOCO produces oils for Harley Davidson vehicles, and their production plants are located in Dallas and Texas, USA. However, they do not make this oil in the USA. Instead, they outsource from Saudi Arabia and Canada. 

In order to maintain the quality of US oil, this oil goes through refinery plants in the United States. Therefore, the lubricant provides the utmost performance. For better clarity, here are its basic specs:

Why Does Genuine Harley Davidson Oil Matter?

To maintain the bike engine, save fuel, and ride long trips, it is necessary to use authentic Harley Davidson oil. And here is what their genuine oil can offer: 

Efficient Engine

The oil is made to function well in all seasons, especially in the winter. During the cold months, motorcycle engines tend to become less efficient due to the thick flow of oil. 

But we commend Harley Davidson for launching oil that performs well all year round. 

Their synthetic and semi-synthetic oils keep the oil’s viscosity lower so that it does not become too thick to flow properly at extreme temperatures. With their low viscosity, they tend to flow easily through the engine. 

As a result, the battery does not need to add extra strain or pressure in terms of starting the engine in extreme heat. So, genuine oil makes the engine more efficient. and the engine provides more power smoothly. 

Anti-Corrosive Feature

The authentic oils from SUNOCO contain rust and corrosion inhibitors. It works against corrosion and friction. 

Consequently, the chains and gears do not collide with other metal parts. It prevents forming tears from friction. 

So, the engine accessories on the bike last longer. And it is enough for us to save some bucks on these metal parts’ servicing and repairs.

Heat Management

The latest Harley Milwaukee eight engines have overheating issues. And to minimize it, their oil helps. 

Furthermore, their synthetic and non–synthetic oil types can sense when the engines use a lot of heat. 

Based on their reading, these lubricants assist in keeping the engine cool from excessive heat. 

What we love about this heat management is that it keeps the engine functioning for a long period of time.

  • Non–authentic thicker oils can leak from the gaskets and engine pan. 
  • The wrong oil type can increase the engine temperature. 
  • An overheated engine, due to the wrong oil, consumes more fuel.
  • If the oil does not have an anti-corrosion feature, the engine units will wear out sooner
