The Benefits of Using Synthetic Oil in Your Harley-Davidson®

The Benefits of Using Synthetic Oil in Your Harley-Davidson®

by Cliff John July 15, 2019

When you own a world-class ride, you quickly learn the importance of keeping your Harley-Davidson operating at peak performance. One of the most frequent questions we're asked - especially from new Harley owners - is whether using synthetic motor oil is the best option.

Choosing the wrong oil cuts both the performance factor and the lifespan of your bike. Most engine wear occurs when you first fire up your motorcycle because it takes a few minutes for the oil to circulate to all moving parts.

Synthetic oils contain additives that help to seriously reduce engine wear by preventing impurities and particles trapped in the oil from settling to the bottom of the sump. Using top grade motor oil not only offers better wear protection for your Harley-Davidson, it boosts performance. Here’s why:


In addition to flowing better in cold weather, synthetic oil resists viscosity changes in high temperatures.


Synthetic motorcycle oil is specially formulated to help dissipate engine heat, especially on air-cooled engines.


Synthetic oil lasts longer, which means fewer oil-related issues.


The structure of synthetic oil makes it slicker than non-synthetics. This ensures smoother engine operation.


Using synthetic oil helps increase fuel economy and your motorcycle’s horsepower by providing better drag resistance.

If you’re a hands-on Harley-Davidson owner, we have complete oil change kits for '17-'19 Milwaukee-Eights and '99-'16 Twin Cam Harley-Davidson motorcycles.  

The Milwaukee-Eight kits include:

  • 5 quarts of Mobil 1 V-Twin 20W-50 synthetic motorcycle oil
  • A Black or Chrome direct OEM replacement oil filter
  • One replacement drain plug O-ring

The '99-'16 Twin Cam kits include:

  • 4 quarts of Mobil 1 V-Twin 20W-50 synthetic motorcycle oil
  • A Black or Chrome direct OEM replacement oil filter
  • One replacement drain plug O-ring

If you’ve never performed an oil change on a Harley-Davidson, now’s the time to get your hands dirty. All you need is a few tools and some free space in your garage. To walk you through this easy process, we created the video below to show you exactly how to perform a complete oil change using one of our oil change kits. The motorcycle being worked on in the video is a 2017 Road King Milwaukee-Eight, but the oil change procedure on a Twin Cam bike is very similar.

In the end, it comes down to this: If your Harley-Davidson owner’s manual doesn’t specify using only synthetic oil, it’s still the best option for your ride.

If you're ready to order the ideal Oil Change Kit for your Harley-Davidson motorcycle, it can be purchased and shipped to your location free of charge. Each kit includes everything you need to keep your bike in top operating condition without having to research between synthetic and non-synthetic motorcycle oils or find the right filter. The tools are up to you.

You can purchase one of our Harley-Davidson Oil Change Kits right on our website or if you'd like to schedule an in-shop service, call us at 301.825.9007 or complete the form below and we'll take great care of you and your bike.

Shipping Delays

We are aware there are orders outstanding. Rest assured that your order has not been missed nor forgotten. Things here at Fat Head Cycles have changed drastically over the past few months and our small operation has had to adjust and adapt to maintain the accuracy and quality of our products. Our supply chains have been affected, distribution centers are backlogged and national shipping agencies have been severely affected by COVID19. Unfortunately, these things are completely out of our control.

The majority of orders containing Sony and Rockford products take between 21-28 BUSINESS days to custom assemble, ship and arrive at your doorstep. Once your order ships you will receive a SHIPPING CONFIRMATION email stating your order is on the way with tracking information. If you have not received this email your order is still in fulfillment que and is working its way up the list. Due to the fluid nature of the supply chain at this time, Fat Head Cycles CANNOT provide ETAs on bundles that have yet to ship as many times we are simply waiting on one small part or another to complete the package.

We here at Fat Head Cycles appreciate you as a customer and will always do the best we can to accommodate and fulfill your requests and your need for the best Harley Davidson audio and performance products in the industry. Thank you for your understanding.
We appreciate you,The Fat Head Cycles Team
