Keep Your Bike Longer With AMSOIL Synthetic Motorcycle Oil

According to an industry survey, U.S. bikers value engine protection and quality above all else.

Over 80 percent of survey respondents rate engine protection and quality as important or very important when selecting motorcycle oil. Viscosity grade and motorcycle-specific formulations are also important or very important to a majority of respondents. Interestingly, price was the sixth most important factor, indicating most bikers are willing to pay a premium for motorcycle oils that help them get the best performance and most years from their engines. Results indicate what motorcyclists want in a motor oil is exactly what AMSOIL Synthetic Motorcycle Oil delivers.

Keeping Bikes Longer

The demographics of the U.S. motorcycle fleet may have played a large role in how bikers responded to the survey. Sales of new bikes, as reported by the Motorcycle Industry Council, reached 452,400 in 2012. However, over half of the 10 million bikes in the U.S. fleet are more than seven years old while almost 25 percent predate 1995. Bikers are keeping their motorcycles longer and selecting lubricants that help them do so by maximizing engine protection and longevity.

Motorcycle-Specific Formulations

Bikers also value motor oils formulated specifically for motorcycles, demonstrating that many understand the unique challenges motorcycles present to lubricants and the need to use lubricants formulated to meet those challenges. Motorcycles run hotter and at higher rpm than passenger cars/light trucks – conditions that require robust oils formulated to resist viscosity loss due to extreme heat and mechanical shear. In many bikes, the oil must lubricate the engine, transmission and primary chaincase simultaneously. Effectively protecting against engine and gear wear while delivering superior clutch performance requires a balanced oil tailored to protect all critical areas. Passenger-car/light-truck motor oils simply aren’t designed to meet the needs of motorcycles. However, 59 percent of respondents indicated an API-certified oil was very important, indicating there is still limited knowledge of lubricant specifications and their applicability.

Synthetics on the Rise

Full-synthetic oils rate as important or very important to 42 percent of respondents. Where bikers once had to be convinced of synthetics’ superiority, many now understand synthetics are better-suited to protect their engines in the toughest riding conditions. The survey also found that the strength of brand reputation and explicit product quality claims are two key differentiators in the market. The AMSOIL brand signifies industry-leading quality due to the company’s presence at the largest and most influential motorcycle rallies in North America – including Sturgis, Daytona Bike Week and Laconia Motorcycle Week – and its sponsorships in the motorcycle racing markets – including AMSOIL Arenacross, Erik Buell Racing, Monster Energy Supercross and Loretta Lynn’s AMA Amateur National Motocross Championships.

More importantly, AMSOIL Synthetic Motorcycle Oil lives up to its performance claims, delivering real-world benefits experienced by countless bikers. Formulated specifically to meet the demands of motorcycles, its exceptional high temperature film strength provides maximum wear protection. AMSOIL Synthetic Motorcycle Oil promotes superior engine cleanliness, wet-clutch performance and transmission protection. Its performance has earned AMSOIL Synthetic Motorcycle Oil a strong reputation for quality, delivering the performance the bikers want.

AMSOIL Motorcycle Products: Something for Everyone

With the introduction of several new and repackaged motorcycle products this year, AMSOIL offers something for every type of biker, from motocross racers and off-road riders to V-Twin and metric enthusiasts. AMSOIL motorcycle products deliver the power, performance and protection that every biker wants, no matter the motivation for getting on the bike.  

Dirt Bike

To satisfy the demand for dirt-bike-specific oil, AMSOIL developed Synthetic Dirt Bike Oil in three viscosities, including 10W-40 (DB40)10W-50 (DB50) and 10W-60 (DB60)

AMSOIL Synthetic Dirt Bike Oil is designed to deliver consistent clutch feel and improve the performance of both bike and rider. Superior clutch consistency lets off-road (trail) riders expertly navigate trail obstacles without sacrificing momentum, helping them stay at the front of the pack. It also allows motocross racers the control needed to accurately time the gate drop to grab the holeshot. 


AMSOIL 20W-40 Synthetic V-Twin Motorcycle Oil was developed to cater to the increasing popularity of Victory and model-year 2013 and newer Indian motorcycles*, providing riders with the security of knowing their bike engines are protected against extreme heat, internal wear and damaging sludge and deposits. 

   AMSOIL Synthetic V-Twin Transmission Fluid and AMSOIL Synthetic V-Twin Primary Fluid are purpose-built for bikers who prefer a dedicated transmission or primary lubricant over a multi-use product, offering customers more options. Together, their robust formulations protect against damage from shock-loading, premature wear, clutch slippage and thermal breakdown and deliver the confidence of smooth starts, quiet operation and more effective riding. 

AMSOIL 20W-50 Synthetic Motorcycle Oil provides superior protection for newer V-Twins, including the ever-popular Harley-Davidson*. In addition to being a cost-effective, high-performance alternative for original equipment manufacturer (OEM)-branded lubricants, AMSOIL Synthetic Motorcycle Oil provides superior primary chaincase, transmission and engine protection in one convenient package. 

AMSOIL SAE 60 Synthetic Motorcycle Oil is a premium oil for early model air-cooled V-Twin engines specifying a 60-weight motor oil. It is specially formulated to excel in wet-clutch lubrication, extreme-pressure protection of gears and preventing rust common to short drives and storage.


To round out the entire motorcycle oil line, AMSOIL 10W-30 (MCT) and 10W-40 Synthetic Metric Motorcycle Oil (MCF) were repackaged and reintroduced with a more specific focus on metric motorcycle applications. 

AMSOIL Synthetic Metric Motorcycle Oil is formulated to provide smooth shifts, excellent wear protection, extreme heat resistance and trouble-free operation in metric cruisers, sport bikes and touring bikes, including Kawasaki, Yamaha, Suzuki and Honda.*
