Motorcycle Oil whitepaper study. Tests performed by Southwest Research show 15 top rated 40W and 50W motorcycle oils head to head in 12 critical tests including Viscosity Sheer Stability, Foam Control, Gear Performance, Price and High Temperature/High Sheer Viscosity. Sever top brands fail out of grade even before the end of a typical testing cycle.

They certainly didn’t think anyone would spend the $200,000 it takes to run these tests so you could see where they rank in quality. AMSOIL says “You can clearly see we are not the best in every test but when you consider our performance across the board conclusively and where it counts, we offer the consumer unmatched quality.”

Note from Ches Cain: And according to the thousands of motorcycle customers of mine there is not one bike out there operating to their full potential until the operator consummates the use of AMSOIL.

Stay tuned here for our own Motorcycle Oil, Maintenance + Gear Performance tests using AMSOIL, and other products in our 1973 Moto Guzzi Eldorado.

The product mentioned in my email signature “Power Foam” solved a major problem in my Moto Guzzi. Anyone who is really focused on maintenance for their motorcycles, especially carbureted models click here. While using castrol 10W40 in 92F heat, we experienced some engine knock when oil temps rose too high. We had jetted down the carb to factory settings and learned the increased fuel from the prior owner was due to the fact he didn’t realize the amount of carbon build-up in the combustion chamber causing increased compression, valve sealing problems and heat soaking.

AMSOIL Powerfoam was used after resetting the idle mix causing a instant notable improved exhaust sound!! I also found another Moto Guzzi owner who discovered the same improvement when using Power Foam on his bike.

Change oil after using Power Foam (within 100 miles is best) on motorcycles w/o oil filters as the product will cause contamination to the oil in small sumps. I also added Amsoil PI to the fuel (or use Quickshot) to continue to clean the valves and combustion chamber area.

You will notice better mileage, throttle response and reduced engine temperatures. If your engine is knocking you will notice a correction here too. In bikes with less severe problems the Quickshot will do just fine while curving the effects of ethanol and short storage effects.

Here is the link once again to AMSOIL Power Foam – One bottle can clean several motorcycle and car engines. I also use it as an exterior block cleaner. One of the most versatile and under-rated AMSOIL products!

A quote from Al Amatuzio Founder:
“I guess the real point of the motorcycle oil white paper and our continuous pursuit of quality is summed up in the final sentence of the editor’s note:
In any case, as motorcycle oils continue to improve, consumers will benefit. “
**As of 2012 the Motorcycle Oil Study remains unchallenged by any of the lubricants tested!

How can a 20W50 protect my transmission when it calls for a 90WT, 85W90 or 75W90?

The answer is simple. The viscosity for engine oils and gear oils are not part of the same scale. In fact a SAE 90 gear oil may actually have less viscosity than a SAE50 (20W50). The illustration clearly explains why. Now you know something most mechanics don’t know.

Note on the above chart – We will soon be publishing a whitepaper study showing that most 90 WT gear oils use the cheapest base stocks thus at the bottom of the scale before early shear. This means they dip into the 40WT (engine oil) realm long before they are replaced, thus the inefficient operation.

AMSOIL Helps Motorcyclist Set Guinness World Record

A few weeks back I heard an exciting story about a woman who set a Guinness World Record on her motorcycle. The official designation was as follows: The longest journey by motorcycle in a single country is 78,214.118 km (48,600 miles) and was achieved by Danell Lynn (USA), who rode throughout the United States of America from 19 September 2014 to 29 August 2015. During this journey, Danell rode through all 48 of the continental United States.

When I learned she was an AMSOIL user, it only seemed natural to reach out and hear more. Her awards are too numerous to list in this brief introduction, so I encourage you to visit her website.

AMSOIL: How long have you been riding a motorcycle? And what was your first bike?
Danell Lynn: I was first on a bike in utero riding along with my mom and dad. But then we did not have bikes for many years and about 15 years ago I got into pillion riding again and then about six or seven years ago decided I wanted to drive and take journeys on my own!

Wet clutches are not a simple concept so when bubba says synthetics are not good for clutches you can show bubba why.Wet Clutches and Synthetics – Bad Combination?

Though it is commonly thought that the use of synthetic oils results in excessive clutch slippage, extensive field and laboratory
testing have disproven that theory. Properly selected synthetic based oils perform very well and do not alter the frictional characteristics of a wet-clutch and can actually improve their performance & longevity. The type of base oil used has the least impact on wet clutch performance.

We have prepared a document showing why you need to carefully choose your motorcycle oil based on additives, not base oils. AMSOIL’s founder is directly responsible for the additives available to make this possible but read this document and pass it along. It’s marvelous!

These oils all have to meet certain frictional coefficients. AMSOIL’s motorcycle oils go beyond that exceeding MA2 – most motorcycle oils can’t claim they meet MA2. Even our 10W40 motor oil (AMO) meets MA although it’s marketed for cars, outperforms most motorcycle rated oils and is what I use in my Moto Guzzi.

AMSOIL motorcycle oils the bar in the industry as these now offer the best in transmission protection and long term storage. Use a oil that really makes a difference. We get plenty of feedback on the incredible improvement in shifting, throttle response and temperature decrease.

Heard using any non “Harley Oil” would cause issues with your warranty?

Well take a look at this! I think you will be happy to read this and based on what was written in a recent Enthusiast magazine, if they go with the statement that you are tied into using their oil, they must provide it to you FREE of Charge! – That’s the law. Ask them to put it in writing! “Ok well please put that in writing so I can get my free oil!”

Read more about AMSOIL warranties and how you are protected by federal law.

Warranty Protected

It is against Federal law for an original equipment manufacturer (OEM) to deny warranty coverage based solely on the brand of lubricant used. The Warranty Secure symbol informs consumers of this fact. Using AMSOIL synthetic lubricants in place of OEM-branded lubricants, or practicing extended drain intervals when using AMSOIL lubricants, does not void new vehicle or equipment manufacturer warranties.

According to the Federal Trade Commission:

The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket or recycled part…. The manufacturer or dealer must show that the aftermarket or recycled part caused the need for repairs before denying warranty coverage. ( (emphasis added)

AMSOIL stands behind its products and the people who use them. If the OEM claims use of AMSOIL products violates the warranty, contact AMSOIL Technical Services (715-399-TECH). For complete information on AMSOIL warranties, contact AMSOIL Technical Services or visit Warranty Secure.

AMSOIL Synthetic Motorcycle oils are not only priced better, but are guaranteed to last twice as long. As stated in AMSOIL Data Sheets, the 20W50 (datasheet) and 10W40 (datasheet) oils have a service life twice as long as the manufacturers suggested interval or one year. AMSOIL resists sheer, adds rust protection and lowers engine temps significantly.

AMSOIL 10W40 Synthetic Motorcycle Oil (MCF) is recommended for Honda, Kawasaki, Yamaha, Suzuki, BMW, Husqvarna and KTM calling for a 10W-40 or 20W-40 viscosity, providing superior protection in engines and transmissions.

AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) is recommended for Harley-Davidson, Buell, Victory, Ducati, BMW, Aprilla and Triumph calling for a 15W-50 or 20W-50 viscosity, providing superior protection in engines, transmissions and primary chaincases.

When it comes to motor oil, what are the primary differences between motorcycle and automotive applications?

  1. 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 accelerate oxidation.
  2. Compression Ratios – 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.
  3. 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.
  4. Variable Engine Cooling – In general, automotive applications use a sophisticated water-cooling system to control engine operating temperature. 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 motorcycles are operated in stop-and-go traffic. Elevated operating temperature promotes oxidation and causes oils to thin, reducing their load carrying ability.
  5. Multiple Lubrication Functionality – In automotive applications, engine oils are required to lubricate only the engine. Other automotive assemblies, such as transmissions, have separate 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 the transmission gears. Many motorcycles also incorporate a frictional clutch within the transmission that uses the same oil.
  6. 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.

Harley Davidson customers require the best 20W50 available designed for your bikes. When you buy AMSOIL you are buying the original synthetic from the manufactures that started the industry back in 1972.

Recently I had a customer call who had switched to AMSOIL and rode along with his father with the exact same bike using Screamin’ Eagle (Harley Synthetic). They both drove the same route, made the same stops and rode at the same speed.
Using the dipstick thermometers, the customer running AMSOIL AMV 20W50 observed a 18*F lower oil temp than the bike running the Harley brand! We hear this daily from our customers.
The New MCV which replaces the AMV enhances protection even more.

AMSOIL also recommends several times yearly the use of the AMSOIL PI Performance Improver (API). This product is a concentrated fuel system cleaner but mostly improves and restores efficient motorcycle and automobile engine operation.

Archived Note From AMSOIL Founder Al Amatuzio:

 (May 2005)

The other day I was reviewing the April Action News and the new G-100 product catalog included in it. The products featured in this issue were our two new motorcycle oils. Anyone reading about these outstanding new oils couldn’t help be impressed by how they totally blew the competition away in head-to-head performance tests. 

Once again, AMSOIL outperforms the competition and puts test results that prove it right there for everyone to see. It’s also interesting that the very bike manufacturer that said not to use synthetic motor oils in their engines now sells and recommends a synthetic with their label on it.
They don’t make it, but they profit from it so now it’s OK to use. That’s very similar to how the other oil companies and automakers badmouthed synthetic motor oils until they began marketing their own.
Are their oils as good as AMSOIL? Not when you look at the tests! AMSOIL has a long history of making lubricants that are the very best. And the way we have shown they are the best is by testing them against the competition and publishing the results in our sales literature or right on the product labels.
I don’t know of any other oil company that does this like we do. But then, I don’t know of any other oil company that makes products as good as we do, so they don’t really have as much to toot their horn about as we do.

We recommend you review Mr. Amatuzio’s other columns on these new Motorcycle oils and other products. (restoring archives section)

Buell Motorcycles now factory fill with AMSOIL!!

Read this article which is spreading wide and far. Buell Racing chooses AMSOIL over prior synthetics and not because of a cash deal but because of a performance and quality factor.

Amsoil and Land Speed Records – This applies more to Diesel owners but we want to show the quality that is put into AMSOIL over competitors products. Amsoil Motorcycle oils are and have always been priority one as the majority of our passenger car users learned about AMSOIL through use in recreational vehicles.

In 2001 Hayes Diversified Technologies (HDT), located in Hesperia, California, began to produce diesel powered tactical military motorcycles for the U.S. armed services as well as the UK and EU NATO countries. Founded in 1961, the company originally manufactured electro-mechanical switches and relays to the military & aerospace industries.

Diesel bike sets new record thanks to Amsoil diesel 5W30 quality.The new HDT motorcycles are diesel machines combining both power and environmentally friendly performance efficiency. We’re talking about a bike that gets 100 miles to the gallon AND can do 100 mph.

The HDT team was out on the Bonneville Salt Flats earlier this month striving to establish new national and world records. Displaying the AMSOIL colors while going through the paces at Bonneville, they offered up quite a number of very strong endorsements with virtually no prompting. “We noticed an increase in horsepower right away when compared to Delvac 1,” said Fred Hayes, founder/CEO of HDT. “What was quite surprising was the condition of the engine after a 50-mile run-in and over 120 full-throttle dyno runs. The camshaft bearings, the small and large end rod bearings, didn’t even look like they had been run. During that series of dyno runs, we registered the highest horse-power and torque readings ever.”

Dave Anderson, AMSOIL Technical Product Manager, had flown to Bonneville to witness and participate in the pursuit of new land speed records. (See 4 and Sept. 6 Updates) Hayes said to Anderson, “Our testing proved that AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil provided better cam bearing lubrication, better transmission operation and less blow-by than our previous oil. We picked up just over one horse power at the rear well.” This is a 3.7% increase and worth a 1 tooth higher gear ratio. “In addition, it appears that overall coolant temperature was down about five degrees.” That is roughly a 2.5% decrease in operating temperatures.

Very few bikers would be opposed to increased horsepower with lower operating temps, simply by switching over the lubricants.

“With over a year of testing, we have found that AMSOIL products continually outperform all other lubricants. AMSOIL provides improved performance, increased fuel economy, lower oil consumption, and significantly reduced engine wear in all operating conditions.”

Worlds Highest Mileage Victory Motorcycle used AMSOIL!

In 2003, AMSOIL Dealer Tim Werder had accumulated 100,000 miles on his 1999 Victory V92C motorcycle.
Werder, of Shawangunk, N.Y., rode an additional 100,000 miles aboard his bike by May 2008. He’s fixin to donate the bike, known as
“Traveler,” to the National Motorcycle Museum in Anamosa, IA.

Werder’s Victory remains the world’s highest mileage
bike for the brand since the first Victory V92C production model rolled off the assembly line on July 4, 1998. “It still attains 60 miles per gallon,” he said.

Amsoil's 10W40 not only gives you problem free operation but the performance is an addiction!For mechanical security, he only runs AMSOIL 10W-40 Advanced Synthetic Motorcycle Oil (MCF) which is the most common choice for Victory brands, and
20W-50 Advanced Synthetic Motorcycle Oil (MCV) in some of his other bikes. “I recommend the full AMSOIL motorcycle oil line to my customers and other
riders,” Werder said. Werder also has another 1999 Victory V92C and a 2003 Victory Vegas.
Werder traveled 200-plus miles daily to his job until a state layoff late in 2009, which helped him achieve a motorcycle mileage nearing 700,000 miles. His high-mileage Victory is the third motorcycle he has ridden past 100,000 miles, and his first past the 200,000-mile mark.

“I also use AMSOIL Shock Therapy Suspension Fluid #10 (STM) in the shocks on the bikes and AMSOIL P.i. Performance Improver gasoline additive in all of my vehicles,” Werder said. “My 2004 Chevrolet Aveo has 157,000 miles, and my wife’s 2003 Subaru Forester has 107,000 miles. Neither has ever had a lick of trouble.”

His daily commute now is only 50 miles. “I’m stunned at the amount of money I’m saving in fuel costs,” Werder said. “I joke with friends that the gas companies
keep sending me ‘We Miss You’ cards.”

Werder continues to ride his bikes year round, even in the cold Northeast winters. In fact, he bought his 2008 CanAm Spyder Roadster GS reverse trike because he wanted to ride through the winter without falling down. He has put 40,000 miles on it in two years.
“I tell everyone they should ride until they can’t, be it due to weather tolerability, cold endurance, whatever,” Werder said. “I just happen to also like riding in cold weather, so my motorcycle riding season simply doesn’t end.”

Within the past several years, Werder also has kept busy fighting for riders through motorcyclists’ rights organizations, including serving as state president of ABATE of New York, Inc. In fact, he broke the 200,000-mile mark on his record-setting Victory motorcycle on the way home from leading ABATE of
New York at its annual motorcyclist rights rally on the steps of the state capitol in May 2008.
He adds his mantra, “Pay attention to the bike’s maintenance basics for longevity. Pay attention to your own riding skills for survivability. And then just ride the hell out of it.”
As Roadkill says, “Ride on.”

AMSOIL Customers Appreciate Greater MPG

Although results vary because of a variety of factors, a common denominator among AMSOIL motor oil users is an improvement in fuel economy. Independent testing reveals that AMSOIL Signature Series 0W-30 motor oil passes the API Energy Conservation Sequence VI test with a rating 38 percent higher than the API minimum specifications.

“The test results show that AMSOIL has the potential to save energy by conserving fuel,” said technical Services Manager Ed Kellerman. “In most cases it can increase mileage, but at the very least you’re getting superior engine protection.”

Ralph Sites, a police officer in Rustburg, Va. said he put AMSOIL 10W-40 Synthetic Motorcycle Oil in its 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.

His first oil change to AMSOIL, improved his mileage to 38 miles per gallon. At 6,500 miles on the engine, after replacing the final drive oil with AMSOIL Series 2000 75W-90 Gear Lube, he improved to 40 miles per gallon. “I switched to AMSOIL for the long-term gain. The improved gas mileage was just a bonus. AMSOIL is less expensive than Honda’s synthetic and I don’t have to change it as often.  It’s a win-win situation.”

Anybody who comes and gets the AMSOIL motor oil in their motorcycle comes back with their cars,” he said.

Likewise, Lance Okeson of St. Paul Minn. gained miles per gallon after switching to AMSOIL motor oil in his 1995 Cutlass Supreme.

Okeson made the switch after learning about AMSOIL from a customer of his at a quick lube where he works. His customer was so enthusiastic about AMSOIL, Okeson did some research on the AMSOIL Website and decided to try the products. A trip from the Twin Cities to Fargo, ND, in a steady 17 mile-per-hour wind, and back showed him an increase from 24 mpg to 30.5 mpg.
