Honda Gold Wing Has 191,000 AMSOIL Miles on Engine

MSF Motorcycle Safety Chief Instructor Michael R. Douglas, of Anaheim CA, wrote, "I currently own a 1989 Honda GL1500 Gold Wing motorcycle. My Gold Wing has 267,025 miles on it. For the past 191,000 miles I have been using AMSOIL Synthetic 10W-40 Motor Oil. I have been changing the oil and filter at intervals of approximately 10,000 miles."

"Recently, I decided to pull the motorcycle apart and have it painted and chromed. After pulling the valve covers off, I was extremely surprised to see how clean the valve train was. The green paint sprayed on by Honda over 10 years ago is still visible. In the rear of the engine by the clutch, is a small piece of plastic 90-degree tube, which allows oil to return to the front half of the engine. With this many miles, this tube is usually either partially or completely plugged with clutch debris and other deposits. If this happens, the front end is starved for oil. The tube in my engine was spotless!"

"I also use AMSOIL synthetic gear lube in the final drive assembly. Keep up the great work! Outstanding products!"


Gold Wing Owner Enjoys Increased MPG

Ralph Sites, a police officer in Rutsburg, Virginia, said he put AMSOIL 10W-40 Synthetic Motorcycle Oil in his 2002 GL 1800 Honda Gold Wing when it had 4,550 miles on the engine.

"I had been getting 30 miles per gallon," Sites said. "I was supposed to be getting 40 to 45 miles per gallon."

His first oil change to AMSOIL improved his gas mileage to 38 miles to the gallon, he said. At 6,500 miles on the engine, he was getting 40 miles per gallon. He also replaced the final drive oil with AMSOIL 75W-90 Synthetic Gear Lube.

"I switched to AMSOIL for the long-term gain. The improved gas mileage was just a bonus. AMSOIL is cheaper than Honda's synthetic and I don't have to change it as often. It's a win-win situation."

He bought the bike new in January 2002, and after putting 12,000 miles on it he estimated he'd saved more than $100 in a matter of a few months because of the increased mileage he got after switching to AMSOIL.


AMSOIL Motorcycle Oil Makes Honda Goldwing Purr

After nearly 15 years of using AMSOIL synthetic motor oils and lubricants, Ken Burkhalter of Chelsea, Michigan, still finds himself pleasantly surprised by the quality of AMSOIL products.

Burkhalter said he loves AMSOIL products and uses them in "anything and everything that comes under my control."

And that's a lot. Burkhalter and his wife, Nancy, ran a 200-acre farm, where they have raised and bred sheep until recenty, when they retired so they can travel.

The three farm tractors, ranging from a small 26 HP to a large 110 HP Massey, are equipped with AMSOIL 10W-40 Synthetic Motor Oil, AMSOIL oil and air filters and AMSOIL Synthetic Tractor Hydraulic/Transmission Oil. Burkhalter also uses AMSOIL gear lubes in his vehicles.

The 2000 Honda Rancher ATV with a 350 cc engine, runs with AMSOIL 10W-40 Synthetic Motorcycle Oil. He bought the ATV for Nancy to run around the farm and check on the sheep. She says the fire engine red ATV with its racks makes it s perfect "lambulance" should any of the babies need rescuing, an event that hasn't happened.

His zero turn lawn mower, log splitter and small engine water (pond_ pump also are equipped with AMSOIL lubes and greases.

He runs AMSOIL 10W-40 Synthetic Motor Oil in his 2004 Chrysler Pacifica and 2002 Buick Rendezvous, along with the farm truck, a 1991 Dodge Dakota. The vehicles also have AMSOIL air and oil filters installed.

Although he registered as a Dealer years ago, he has used the products for himself rather than selling them to others.

"While I proselytize AMSOIL products to all who will listen, I just send them to the AMSOIL website to learn more," Burkhalter said. "I'm a great promoter, I just didn't have the time to handle sales efforts. Now that I'm retired I might rethink that."

Although Burkhalter trusts the quality and performance of AMSOIL motor oils, lubes and filters, he has been newly impressed with AMSOIL products in his 1999 Honda Goldwing GL1500SE. He purchased it with 15,000 miles on the engine. He put 5,000 miles on the oil and fluids installed by the dealer he bought the bike from and then installed AMSOIL 10W-40 Synthetic Motorcycle Oil. "Upon riding the bike after the change I was blown away," Burkhalter said. "Words alone cannot describe the remarkable performance change."

He reports the engine starts easier and quieter and idles significantly faster.

"I'll have to adjust the idle speed back down," he said. "It runs like everything is made from silk. The engine is so quiet you can barely hear it at 70 mph, and the smooth sound it makes is so stunning, I have been driving with my radio off just to enjoy the engine purr."

Besides the purring of the engine, Burkhalter experienced an immediate improvement in shifting ease on the Goldwing. "I thought it might be my over-fertile imagination, but looking at the shop manual closer I find that the transmission runs in the engine oil (not seperate) so the extreme smoothness. ease of shifting and lack of gear gnashing can only be attributable to the use of the AMSOIL motorcycle oil.

"I'm not sure why i'm surprised, having been a satisfied user for more than a decade, but the difference in the bike was drastic."

What You Need To Know About Motorcycle Oils

Overview
As with any vehicle equipped with an internal combustion engine, proper lubrication is essential to insure performance and longevity. It is important to point out that not all internal combustion engines are similarly designed or exposed to the same types of operation. These variations in design and operation place different demands on engine oils. Specifically, the demands placed on motorcycle engine oils are more severe than those placed on automotive engine oils. Therefore, the performance requirements of motorcycle oils are more demanding as well.

Though the degree may be debatable, few will disagree that a difference exists between automotive and motorcycle applications. In which area these differences are and to what degree they alter lubrication requirements are not clear to most motorcycle operators. By comparing some basic equipment information, one can better understand the differences that exist.

There are six primary differences between motorcycle and automotive engine applications:

Operational Speed - Motorcycles tend to operate at engine speeds significantly higher than automobiles. This places additional stress on engine components, increasing the need for wear protection. It also subjects lubricating oils to higher loading and shear forces. Elevated operating RPMs also promote foaming, which can reduce an oil's load-carrying ability and accelerated oxidation.

Compression Ratio - Motorcycles tend to operate with higher engine compression ratios than automobiles. Higher compression ratios place additional stress on engine components and increase engine operating temperatures. Higher demands are placed on the oil to reduce wear. Elevated operating temperatures also promote thermal degradation of the oil, reducing its life expectancy and increasing the formation of internal engine deposits.

Horsepower/Displacement Density - Motorcycle engines produce nearly twice the horsepower per cubic inch of displacement of automobile engines. This exposes the lubricating oil to higher temperatures and stress.

Variable Engine Cooling - In general, automotive applications usa a sophisticated water-cooling system to control engine operating temperatures. Similar systems can be found in motorcycle applications, but other designs also exist. Many motorcycles are air-cooled or use a combination air/oil design. Though effective, they result in greater fluctuations in operating temperatures, particularly when motorcycle are operated in stop-and-go traffic. Elevated operating temperature promotes oxidation and causes oils to thin, reducing their load carrying ability.

Multiple Lubrication Functionality - In automotive applications, engine oils are required to lubricate only the engine. Other automotive assemblies, such as transmissions, have seperate fluid reservoirs that contain a lubricant designed specifically for that component. The requirements of that fluid differ significantly from those of automotive engine oil. Many motorcycles have a common sump supplying oil to both the engine and transmission. In such cases, the oil is required to meet the needs of both the engine and transmission gears. Many motorcycles also incorporate a frictional clutch within the transmission that uses the same oil.

Inactivity - Motorcycles are typically used less frequently than automobiles. Whereas automobiles are used on a daily basis, motorcycle use is usually periodic and in many cases seasonal. These extended periods of inactivity place additional stress on motorcycle oils. In these circumstances, rust and acid corrosion protection are of critical concern.

It is apparent that motorcycle applications place a different set of requirements on lubricating oils. Motorcycle oils, therefore, must be formulated to address this unique set of high stress conditions.

AMSOIL Synthetic Dirt Bile Oil Maximizes Performance

Consistent Clutch Feel - Clutch slippage or inconsistent clutch feel can prevent dirt bike riders from riding as fast or effectively as they like. To keep the engine within the power band, riders often modulate the clutch, increasing the opportunity for clutch slippage if low-quality lubricants are used.

AMSOIL Synthetic Dirt Bike Oil's superior friction-durability properties help minimize clutch slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when maneuvering around obstacles on the trail. In an extreme simulated-start test, AMSOIL Synthetic Dirt Bike Oil continued to deliver consistent clutch feel following 32 simulated race starts, while a leading original equipment manufacturer (OEM)-branded oil demonstrated inconsistent clutch-lever action and poor clutch feel after 16 starts. The clutch plates lubricated with AMSOIL Synthetic Dirt Bike Oil remained clean and in good overall condition, while the plates using the OEM oil revealed discoloration and wear. AMSOIL Synthetic Dirt Bike Oil's superior performance helps instill in riders the confidence that their bikes will perform consistently in all types of riding conditions.

Racing is Research - AMSOIL corporately sponsored supercross and motocross racers identified consistent clutch feel as a key performance attribute. At the time, there was no dirt-bike-specific oil on the market that provided the level of clutch consistency professional and amateur riders demand. Consistent clutch feel is critical to motocross riders during starts to keep the bike from lurching forward prior to the gate dropping. Trail riders, meanwhile, need consistent clutch feel to confidently navigate obstacles without having to shift gears and lose momentum.

In-Depth Product Development - The process to develop Synthetic Dirt Bike Oil relied on a combination of lab and track testing. Clutch feel is inherently subjective, which creates challenges in designing a lubricant that delivers consistent clutch feel. To overcome that challenge, AMSOIL designed The Extreme Simulated-Start Test on Dirt Bikes. The test allows AMSOIL engineers to apply accelerated stress to a dirt bike's clutch in order to monitor clutch feel produced by a candidate lubricant.

The test uses a 2014 Honda CRF450R attached to a dyno. While in second gear, the test administrator holds the clutch at the point just prior to engagement, similar to the way a rider would hold the bike in the gates during a race start. The clutch is then released and the bike is run to fourth gear, simulating the time from the drop of the gate to the first corner in a race. The rear wheel is not allowed to slip during the test, placing additional stress on the clutch. Test administrators look for consistent lever action and feel as they wait to let out the clutch and as they shift the bike through the gears.

AMSOIL Synthetic Dirt Bike Oil was also subjected to extensive on-track testing in the bikes of GEICO/AMSOIL/Honda Factory Connection and other professional riders. A combination of rider feedback and lab testing resulted in the final formulation of Synthetic Dirt Bike Oil. Its performance in lab and track testing dispels the myth that synthetics are "too slippery" and make clutches slip. Results also demonstrate that AMSOIL Synthetic Dirt Bike Oil delivers consistent clutch performance while helping extend clutch life. (Buy Online)

NOACK Volatility Test is a Critical Measurement of Motor Oil Quality

AMSOIL was the first motor oil company in North America to use the NOACK volatility test to measure motor oil quality and performance. Although competing motor oil companies initially paid no attention to NOACK results, the test has since become a critical measurement tool throughout the industry.

Modern engine designs generate more heat than ever, accentuating the importance of the NOACK volatility test for determining an oil's ability to provide an adequate level of protection and performance. More horsepower, turbo chargers and aerodynamic styling have created extremely hot environments that receive less cooling from outside air, and high heat leads to oil oxidation, deposits and thickening in conventional oils.

Top quality for the current API SM motor oils specification, gasoline motor oils cannot experience a weight loss of more than 15 percent in the NOACK test. AMSOIL Synthetic Motor Oils were exceeding modern requirements over 20 years ago, while many current motor oils still have a hard time meeting this minimal requirement, increasing wear, fuel consumption and emissions.

As seen in the graph, AMSOIL Synthetic Motor Oil easily passes the NOACK Test and falls well below the the maximum 15 percent volatilization (burn off) rate dictated by the API SM motor oil specification, while the Royal Purple volatilization (burn off) rate is over 11 percent and the Lucas Oil FAILS the test with a volatilization (burn off) rate of over 40 percent.

Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
