Run cooler! Reduce crankcase temperature. AMSOIL Synthetic Motorcycle Oils deliver maximum protection, power and fuel efficiency for all makes of motorcycles. Recommended for all V-Twin and other motorcycle engines. Superior 12+ TBN synthetic formulation provides long service life and maximum protection against engine wear. Superior anti-wear and detergent/dispersant packages. AMSOIL Synthetic Motorcycle Oils contain no friction modifiers and are wet clutch compatible.

AMSOIL Synthetic Motorcycle Oils
AMSOIL synthetic 10W-40 and 20W-50 motorcycle oils give motorcyclists what they need: superior wear protection for high-stress motorcycle engines and transmissions and clutches that stay clean and deposit free.

The AMSOIL Advantage
Motorcycle manufacturers want the best protection possible for their equipment, calling for rugged oils that exhibit high-temperature deposit control additives. AMSOIL Synthetic Motorcycle Oils are specially formulated with the best synthetic basestocks and high-performance additives to provide tough lubricating protection for all four-cycle motorcycle and ATV engines in the most demanding operations.

AMSOIL Motorcycle Oils are formulated for both water-cooled engines and the unique demands presented by air-cooled V-twin motorcyle engines, including Harley-Davidson. Conventional petroleum oils break down and oxidize when faced with high temperatures, such as those experienced when idling in traffic, contributing to the formation of deposits, sludge and varnish. AMSOIL withstands oil breakdown and oxidation in high temperatures, holds contaminants in suspension and keeps engines running cool and clean.

Zinc and phosphorus additives are extremely important to engines faced with high-pressure conditions, especially motorcycle engines, which typically have steep cam slopes, creating high pressure between the parts. In motorcycles, friction modifiers (prevalent in automotive oils) have been attributed to engine start failures, a rough running feel, increased fuel consumption due to higher engine stall speeds and other problems. AMSOIL Synthetic 10W-40 and 20W-50 Motorcycle Oils have beefier antiwear and detergent/dispersant packages with no friction modifiers, keeping motorcycles running smoothly and efficiently, while allowing for extended drain intervals of up to twice the manufacturers' recommendations.

How do other motorcycle oils compare to AMSOIL Synthetic Motorcycle Oils in wear protection?

Wear Protection
AMSOIL submitted popular motorcycle oils to Four-Ball Wear (ASTM D 4172) testing and compared the results to those of AMSOIL Synthetic 20W-50 and Synthetic 10W-40 Motorcycle Oils.

As seen in the graph, none of the popular motorcycle oils compared favorably to the AMSOIL motorcycle oils in wear protection.

AMSOIL Synthetic Motorcycle Oils contain significantly higher levels of zinc and phosphorus than competing oils, and while simply adding more zinc and phosphorus doesn't insure good performance, AMSOIL has formulated motorcycle oils with the best additives in the optimal quantities to provide superior wear protection.

A Four-Ball Wear Test was conducted at 302°F/150°C, a higher temperature that would typically be associated with motorcycle oil operating temperatures in extreme high-performance situations. AMSOIL motorcycle oils protect better in higher temperatures than any of the tested motorcycle oils do, leaving a wear scar up to 80 percent smaller.

Some motorcycle transmissions and engines share a common oil sump, so the engine oil must also provide wear protection to the transmission gears, which, according to Motorcycle Consumer News (Aug. 1998) are subject to high gear surface pressures and gear rotation speeds. The superior performance of the AMSOIL Motorcycle Oils in the Four-Ball Wear Test applies here too.

A situation my daughter, Lyn, told me about recently got me to thinking about how good it is to be able to blend our own oils and have complete control of our own product quality.

Lyn loves to ride motorcycles. She recently purchased a Harley-Davidson bike and took it to the local Harley shop to have our new AMSOIL Motorcycle Oil installed. The mechanic took issue with her not using the oil Harley-Davidson sells, saying, "I'll use AMSOIL motor oil when AMSOIL starts making motorcycles!"

How would you answer a challenge like that? I was pleased to hear Lyn's response. She said, "I'll start using Harley-Davidson motor oil when Harley starts making oil!"

Perfect! The fact is that Harley-Davidson, like so many other "brands" of oil, contract with one or more oil companies to make their lubricants. Often, the decision as to who actually makes a private labeled product is based on low bid, and like almost everything manufactured by a low bidder, short cuts are taken in order to meet the low price.

I understand that Harley-Davidson has contracted with one company for a number of years to make their oil. That's good, but it doesn't change the fact that they make motorcycles, not oil. Now consider all the other private label oils out there. Every manufacturer that makes equipment with an engine has its own name on an oil bottle. That includes all the major auto manufacturers, the makers of motorcycles, ATV's, snowmobiles, lawnmowers, farm equipment, you name it, they all have oils. But none of these equipment manufacturers actually make an oil. They sell oil to make more money, and they often price these oils well above the going rate for competitive lubricants because, like Harley-Davidson, they can specify or create the impression that only their oil be used in their equipment.

Now there's nothing wrong in having a goal to make money, but let's get real here. Why would anyone want to use a product manufactured down to a price rather than a product manufactured up to high quality standards? We have tested a number of these private label motor oils and two-cycle oils and we found many are mediocre quality products. None of them even comes close to performing as well as AMSOIL lubricants, and that's a fact!

I'm not taking shots at Harley-Davidson. They make good motorcycles (although I liked my Goldwing better). And I understand their concern that normal automotive oils not meeting API C specs shouldn't be used in their bikes. But when they imply that AMSOIL Motorcycle Oil is not as good as their brand or I hear that one of their dealers recommended not using AMSOIL, I get a little hostile. Thise kinds of statements are the very reason we introduced our motorcycle oils in the first place. And when we say use our 20W-50 motorcycle oil in V-Twin motorcycle engines, that definately includes Harley-Davidson motorcycles!

Our Motorcycle Products Brochure, G-391, includes wear comparisons of AMSOIL Motorcycle Oils vs other oils, including H-D "Genuine." Both our oils demonstrate superior wear protection over all other tested brands. Interestingly enough, the highest wear scar in this test turned out to be Harley-Davidson's own "Genuine" oil!"

There is a good reason why AMSOIL Motorcycle Oils protect so well against wear. They are formulated with significantly higher levels of zinc and phosphorus, which when included in proper formulation with other high quality additives, provide superior wear protection at the high operating temperatures typical of motorcycles. In addition, synthetic oils inherently reduce sump temperatures so the engines actually run cooler.

The fact is, Harley would do well to have AMSOIL make their oils for them. Then they could be assured that their oil was indeed a superior product. As it is, there may be absolutely nothing wrong with their oil for use in average service, but I guarantee you that as the oil temperature gets hotter, like it does when sitting in traffic on asphalt on a hot summer day, the Harley-Davidson with AMSOIL in the crankcase is going to be far better protected and run far cooler than the bike with H-D "Genuine" oil in it. There's just no two ways about it!

So, my daughter Lyn will be going back to this mechanic armed with the facts about AMSOIL Motorcycle Oils and a few facts about H-D oil. Nobody's going to tell her that her dad's oils are not the very best. She knows better, and she's on a mission to prove her point. Who knows? Knowing Lyn, she might sign up another AMSOIL Dealer in the process!

Although Harley-Davidson Motorcycle Company routinely tells its customers they must use “Harley-specific” motor oils and lubes, some riders are realizing AMSOIL motorcycle oil keeps the popular bikes running cooler and smoother.

Jim Murphy and Jim White, partners at a Lehman Trike Conversion business in Martinsburg, W. Va., spread the word that AMSOIL makes the best products – even for Harleys. (read article)

Terry Campbell of Lincoln, California, a long time Honda rider, bought his 2003 Harley-Davidson Dyna Superglide new. "The biggest thing I noticed was the big twin engines run hot," Campbell said. He initially ran Harley Syn3 in the crankcase, Redline Heavy Shock in his transmission and Redline 75W-140 in his primary. "Wee, the Redline didn't work any better than the Syn3, in fact, my transmission shifted worse. The Harley Syn3 ran too hot, and the Redline was sticky." Campbell said.

He now runs AMSOIL in the engine, transmission and primary. "So, I've been running AMSOIL in all three cavaties," Campbell said. "It has made quite a difference. My engine is running at least 30 degrees cooler, my transmission shifts much smoother and my primary chain is quieter." (read article)

I wanted to let you know how happy I am with your AMSOIL 20W-50 Synthetic Motorcycle Oil. I own a 2006 Harley-Davidson Sportster with 5,000 miles on it. Since the bike was new I've only used Harley-Davidson oil in the engine and Sportster gear lube in the transmission and primary chaincase.

After reading your "Study of Motorcycle Oils" I decided to switch to AMSOIL. That was the best thing I've ever done for my Harley-Davidson.

From day one I have had problems down-shifting, especially when the bike was cold. It would hang up between gears and I couldn't get it free before the light at the signal turned green. Very dangerous.

After 5,000 miles it was still doing it. Now, after I started using AMSOIL in my engine and transmission, the problem has ceased completely from the minute I put it in. No matter how easy I down-shift I can't make it hang up between gears.

Thank you so much for your incredible oil. I'll never use any other brand again.

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!”

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 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.

Motocross racer Chris Price of Yadkinville, North Carolina, competes on a 2005 Honda CR85 at a couple of local tracks. One day at the track. Mike Price (chris's dad) installed a new clutch on his bike before racing began.

"I forgot to check the clutch for play because the plates will swell when they are new," said Mike. He said he could hear the engine screaming as soon as the 11-year-old racer left the gates. The motor nearly quit altogether and Price fell to last place, but he didn't stop riding.

"I finished the whole seven laps and took second place, the clutches held together but were slipping the whole time" said Price.

After getting the bike back to the trailer the Prices changed the oil and checked the clutches.

"Everything looked great. My dad said if it wasn't for AMSOIL 10W-40 Motorcycle Oil in the transmission, the clutches would have burned out after two laps," said Price.

Price uses AMSOIL Dominator in the engine and an AMSOIL Power Sports Air Filter along with the AMSOIL Motorcycle Oil in the transmission.

"The oil never broke down in the severe heat that built up in the clutches, and AMSOIL Dominator is the best that has ever been made," said Mike "Customer for life."

Hayes Diversified Technologies USA is working on development of commercially available motorcycles, tentatively scheduled for release by early 2008. The company is so impressed with AMSOIL that these motorcycles will come factory-filled with AMSOIL synthetic lubricants. This quote from HDT's website sums up their experience with AMSOIL: "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." (read article)
