AMSOIL vs. Harley-Davidson SYN3

Check out how AMSOIL V-Twin Oil vs. Harley-Davidson SYN3 Performs

Bikers always want to know how AMSOIL products compare to the competition, particularly against Harley-Davidson oil. Read on to see how AMSOIL V-Twin Oil vs Harley-Davidson SYN3 compare.

It’s no wonder since Harley-Davidson dominates two-wheeled culture despite the resurgence of the Indian brand and the rising popularity of adventure bikes and everything you can do with them.

The company’s founding is a great story. William Harley and Arthur Davidson built their first motorcycle in a 10×15 shed right here in our home state of Wisconsin. While the duo’s 116-cc prototype bike lacked the power to ascend the hills around Milwaukee, it turns out it had the power to reshape American culture.

That’s one reason several AMSOIL Dealers and employees ride Harleys.

But, what about Harley-Davidson motorcycle oil?

To see how AMSOIL Synthetic V-Twin Motorcycle Oil performs vs. Harley-Davidson oil, check out the performance-test results for yourself.

Amsoil vs Harley SYN3

AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil resists viscosity breakdown 6X better that Harley-Davidson SYN3 Oil.*

Why viscosity matters

Viscosity is the most important property of a lubricant. While it’s defined as “resistance to flow,” it helps to think of viscosity as the oil’s thickness.

Your motorcycle engine, transmission and primary are designed to use oil of a specific viscosity, likely 20W-50 if you’re riding a Harley. The higher the numbers, the thicker the oil. So, a 20W-50 is thicker than the 5W-20 oil you use in your truck.

Oil that’s too thin reduces wear protection

Oil that’s too thin for its application won’t form a durable fluid film on metal components. The oil film protects the bearings from wear, helps keep the piston from scuffing against the cylinder wall, protects the transmission gears, guards against compensator wear and more.

In the transmission, for example, the oil must be thick enough to develop a strong fluid film to cushion the gears against shock-loading and quiet loud “thunks.” This promotes smooth, quiet shifts.

It’s the same story in the primary. The oil must protect the compensator from wear to prevent noise. If it doesn’t, you’ll find yourself on your phone reading the glut of content about Harley compensator noise and how to fix it.

The compensator acts like a shock absorber between the engine and transmission, helping prevent engine vibration from interfering with the transmission. When it wears out, it makes a ticking or knocking noise.

Avoiding this scenario seems easy enough – just use a good oil that maintains its viscosity and forms a strong, protective film on parts.

Motorcycles destroy lesser oils

That’s easier said than done.

Motorcycle engines, transmissions and primaries can be brutal environments that take a toll on oil. The mechanical shearing action of metal parts churning at thousands of rpm (particularly transmission gears) combined with extreme heat can cause oil to lose viscosity and become thinner.

Oil that’s too thin reduces wear protection and can lead to “thunking” transmission gears and a noisy compensator.

And nothing derails your pursuit of freedom on the open road like a noisy bike.

To help avoid these problems, use a motorcycle oil that maintains its protective viscosity, like AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil. Compared to Harley-Davidson SYN3 oil, it resists viscosity breakdown 6X better for improved protection against compensator and transmission gear wear.*

So, while we love Harley’s rich history of freedom and independence, we’ll stick with AMSOIL Synthetic V-Twin Motorcycle Oil over Harley-Davidson SYN3 oil.

AMSOIL 10W-30 and 10W-40 Synthetic Metric Motorcycle Oils have been available for the unique needs of high-revving, hot-running metric motorcycle engines, particularly sport bikes like the Kawasaki* Ninja*, Yamaha* YZF and Honda* CBR; and touring bikes like the Honda Goldwing.* Now, AMSOIL 15W-50 Synthetic Metric Motorcycle Oil, product code MFF, is recommended for motorcycles that require 15W-50 motorcycle oil, including those made by Ducati*, BMW*, KTM*, Yamaha, Triumph* and Royal Enfield*.

The new 15W-50 Metric Motorcycle Oil is for certain touring bikes, particularly BMW and Ducati models, but it is primarily for adventure bikes, which are equipped for both on- and off-road riding. Popular examples include the BMW R 1200 GS Adventure, Triumph Tiger* 1200 XR and Ducati Multistrada* Enduro*.

AMSOIL 15W-50 Synthetic Metric Motorcycle Oil offers riders the security that comes with using an oil as precisely engineered as the bikes in which it’s used. It meets the exacting standards of industry and original equipment manufacturer (OEM) specifications. It is formulated to deliver the benefits riders most seek, including:

Robust power and acceleraton – By fighting wear and power-robbing carbon, AMSOIL Synthetic Metric Motorcycle Oil helps preserve engine power for maximum torque and acceleration. The oil’s precise frictional properties promote confident clutch feel, helping riders enjoy pinpoint control when staring from a dead stop and navigating terrain.

Next-level wear protection – Guarding against wear despite high RPM and intense heat results in long-lasting components that require less maintenance, letting riders focus on reaching their destinations, not fixing their bikes.

Fights extreme head – Resisting breakdown and maintaining viscosity in extreme heat offers excellent protection during longer drain intervals while preserving fuel economy.
