Best Synthetic Oil for a Harley

If you’re like most Harley riders, you take great pride in your bike. You want to make sure that it’s well taken care of and that the motor oil is of the best quality. Many riders mistakenly think that they can use car motor oil in their Harleys, but this is not the case. In fact, using motorcycle-specific motor oil is essential for keeping your Harley running well. In this article, we’ll discuss why synthetic oil is best for Harleys, explain why motorcycle-specific motor oil is important to your bike’s engine health, and discuss the best synthetic oil for a Harley.

Why Choose Synthetic Motor Oil?

If you’re interested in both protecting your bike from undue wear and tear and optimizing engine performance, chances are you’ll want to purchase a synthetic motor oil for your next oil change. But why should anyone choose synthetic motor oil over conventional oils, when full synthetic and even synthetic blends tend to cost more?

In short, there’s nothing wrong with regular motor oil—it’s just that synthetic motor oils have literally been engineered to offer superior performance, lubrication, and even keeps the engine cleaner as it runs. Other benefits of choosing synthetic motor oil include:

·      Increased fuel economy and gas mileage

·      Better overall lubrication, leading to longer engine lifespan due to decrease wear from friction

·      Fewer oil changes are needed, as you can drive more miles between oil changes (saves money and time)

·      Fewer noxious emissions

·      Improved engine response when starting

·      Keeps engine clean and actively prevents sludge and deposits from building up

·      Keeps engine adaptable to weather extremes

·      Reduced engine drag

·      Increased predictability of performance

While full synthetic motor oil is often full of additives that promote lubrication, cleanliness, and reduce shear (or wear) on your engine, you can also select a synthetic blend motor oil. This blend of conventional and synthetic motor oils offers some of the benefits of synthetic engine lubricants at a lower price point.

Why You Should Use Motorcycle Motor Oil Over Car Motor Oil

It might be tempting to think that all engine lubricants are interchangeable, whether for your motorcycle, car, RV, or boat. However, many motor oils are engineered specifically these days to cater to an engine’s unique performance needs. Motorcycles are no exception to this rule, and generally speaking, it’s best to use motorcycle oil over regular car motor oil in your Harley.

Why is this? Well, synthetic car engine lubricants are typically designed with the goal of reducing friction and keeping the engine clean through the use of detergent additives. Oftentimes, these additives are made with ash, which, if used to lubricate your motorcycle, may result in unwanted deposits on the valve train or piston crowns. This can cause premature engine wear due to pressure buildup, perforation, and burning of the additives.

Motorcycle engine lubricants, on the other hand, are designed to facilitate movement both within the engine and within the gearbox. As such, they are designed to balance friction characteristics with the intention of lubricating the wet clutch, which transfers power to the drive train. If car motor oil is used instead, the friction levels may be too low—resulting in slippage of the clutch.

In short, motorcycle oil needs to lubricate the moving parts of the engine and gearbox, but not without the little bit of friction necessary to keep things moving along. Car motor oils—even full synthetic ones—are not designed with this in mind, and as such are not an ideal lubricant for your bike if you want to keep it running its best for a long time.

Can I Change My Harley's Motor Oil Myself?

Now that you know that you need a motorcycle-specific motor oil for your Harley, you may be wondering if you can change your motor oil yourself. This can not only end up saving you money but offers you the piece of mind of knowing that you’ve put quality motorcycle oil in your sump—and it can even be a little fun too. However, if you are inexperienced with engines and changing oil or don’t have the tools to do so, there’s nothing wrong with having your Harley serviced by a professional mechanic. Just ask for a full synthetic oil for that peace of mind!

Where's the Drain Plug on a Harley?

A common question with DIY motorcycle oil changing is where to find the drain plug on a Harley to remove the spent oil from the sump. Once your Harley is upright and you have the tools you need to complete the oil change, you can locate the drain plug behind the seat and underneath the frame of your bike. It takes a 1.6cm socket wrench to loosen and remove the drain plug.

What's the Best Synthetic Oil for a Harley?

Purchasing a motorcycle is a significant investment that can provide the rider with a lot of freedom and enjoyment—but it does require a little bit of maintenance and TLC every now and then to keep things running their best. If you’re looking for better fuel economy, better starts, and boosted performance in all sorts of weather, chances are you’ll want to select a synthetic oil for your Harley. So, what’s the best synthetic oil for the job?

When it comes to maintaining your motorcycle, there’s no sense in settling for second best. Selecting a full synthetic motorcycle oil not only improves performance, but it increases the lifespan of your bike as well and helps it hold its value.
