Erik Buell Talks About AMSOIL Motorcycle Oils

Reduces Friction, Heat and Wear
In high heat conditions, AMSOIL Synthetic Metric Motorcycle Oil exceeds the standard for high-temperature film strength to deliver excellent wear protection. It keeps engines running cool by effectively reducing friction and heat, and it contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to volatility and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

• Premium wear protection
• Smooth, confident shifts
• Cool, clean performance

Smooth, Confident Shifts
AMSOIL Synthetic Metric Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It is engineered to control heat and prevent slippage and glazing, promoting longer clutch life.

Controls Foam
High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit.

Provides Extreme Pressure Quality Protection for Gears
With AMSOIL Synthetic Motorcycle Oil, there is no need for separate transmission lubricants. It is absolutely shear stable and will not thin out from mechanical activity. AMSOIL MCF performs like a gear lube without the negative effects of extreme pressure additives. In the FZG gear test, AMSOIL MCF achieved a perfect score with a zero wear rating (see photo below).

Delivers Superior Rust Protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage, such as uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to motor oils. Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-rust agents that deliver superior rust protection. With its high 11.1 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.

Provides Excellent Wet Clutch Performance
AMSOIL Synthetic 10W-40 Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. AMSOIL MCF controls heat and prevents slippage and glazing, helping improve clutch life. AMSOIL Synthetic 10W-40 Motorcycle Oil meets the wet clutch frictional requirements of JASO Standard T903: 2006, MA/MA2 and ISO-L-EMA2 of ISO Standard 24254:2007.

MIXING AMSOIL
AMSOIL Synthetic 10W-40 Motorcycle Oil is compatible with conventional and synthetic motor oils;
however, mixing oils may shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL motorcycle oil.

SERVICE LIFE
Recommended for use up to twice the motorcycle manufacturer-recommended change interval (miles/hours) or one year, whichever comes first, in engines and transmissions.

When using an oil filter other than AMSOIL Ea® Motorcycle Oil Filter, change the filter at standard intervals. Racing or modified engines are excluded from extended drain interval recommendations; oil changes are at the owner's discretion.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

I put this into my recently acquired 2002 Goldwing GL1800 with 36,000 miles on it. The previous owner has been using Diesel engine oil - who knows why. Shifting was very clunky and neutral was difficult to locate. I ran 1,000 miles with Amsoil 10W-30 and then changed the oil again. Now I have smoother shifts and neutral is easier to locate. Pretty cheap fix for a 17 year old bike.

Great Product

Been using this in my BMW for years. When I first bought the bike I used BMW OEM oil. The bike always had a slight vibration. I changed and balanced my tires. No change. I changed the engine oil with Amsoil and the vibration went away. The engine RPM increased by 300 rpm. i never thought that the lubricity of oil could reduce internal drag this drastically. I read a white paper on this and the anti-foam properties significantly reduce air mixed with the oil. Amsoil is all I use in all my vehicles now!

I recently joined the AMSOIL family after talking with several other people over the years about their experiences. I am extremely satisfied with the product and immediately noticed smoother shifting and idle. I was however disappointed in the design of the one gallon jugs.

Best protection and better shift feel

I have two Triumph triple 900 motorcycles, a '95 Tiger and a '99 Legend, both of them purchased as used bikes. I initially used Mobil 1 motorcycle oil as specified in the owners manual, but the shifting seemed a bit stiff, so I switched to Royal Purple. This offered no improvement over the Mobil 1, and since I had just started using Amsoil in my cars, I went ahead and added some motorcycle oil to my next oil order.
The improvement in shift feel was immediately apparent, and I also noticed that the old oil was much cleaner when I changed it out at the end of the season, not breaking down like the other brands.
Since my 2006 Honda Odyssey currently has over 260,000 of only Amsoil miles on it, I feel like my bikes should last forever!

Motorcycle Oil

I am currently riding an 04 Kawasaki nomad 1500. These 1500's are know for there torque and reliability, however they get a valve knock after they get some mileage on them. I have been running Amsoil in my truck for years but have been reluctant to switch my bike over because of the wet clutch system. I had tried to run a synthetic oil before in it but because of the wet clutch synthetic is to slippery to run and clutch slipped. Amsoil must have done the research on there synthetic oil for metric bikes as I experienced no slippage and the valve noise seems completely gone. I just switched bike to amsoil in late August so the longevity teat I cannot speak to but can't imagine it differs from the motor oils. Great products they have.

Both bikes got very hot, got them checked next day at nearest dealer, even they said it's the quality oil the oil that prevented engine damage and oil tested "good to go".
This oil may cost more than other synthetic motorcycle oils, but you get what you pay for. I'll never use any other oil in my British Bikes, or Amsoil products in anything I ride, drive, etc.

I had used another oil in my concours 1400 for a long time but had to change it often. I also noticed shifting would get clunky very fast. I decided to try amsoil and I'm glad I did. This oil is holding its own. No clunky shifting and it's lasting twice as long as the old oil.

I am an avid motorcyclist that have ridden all over this country on my 2010 HD Ultra Classic. When I purchased the bike new in June of 2010 I immediately changed the factory oil at 500 miles to Amsoil 20W50. It has over 125,000 miles on it now and has never had the heads removed from the engine yet. I just did another 5,000 mile oil change and it was down 1 quart in 5,000 miles. 5,000 mile oil changes have been the normal it's entire life. I am a very convinced customer of this product!

Something new with use.

Routinely changing the oil on my Gsx-s750 brings with it a new appreciation for Amsoil oil. I'm on my 3rd oil change on this bike and I swear the oil maintains its clarity further and further into each new oil change. Currently approximately 2200 miles into my last change and the oil is still clear in the viewing window. Its a little darker in color like an IPA but still clear. Clarity has to be associated with cleanliness, and therefor my engine must be very clean. One happy camper.

Best motorcycle oil

I had been using Mobile 1 in my Valkyrie. During a trip from Denver to Tucson on a Memorial Day weekend I noticed clunky shifting when I got to Tucson. The temp was pushing 100 and we encountered some stop and go traffic. The tranny was definitely shifting hard. It seemed that the oil had broken down more than normal. That summer I was at a goldwing rally and stopped at the Amsoil booth to talk with a representative. I told him about the hard shifting. He told me that Mobile 1 had reduced the amount of silicates in their synthetics. He told me to try the 10W-40 Metric. He said I would notice a difference. He's the rep, he has to say that. However, I had heard good things about Amsoil from some other riders so decided to give it a try. What an unbelievable difference. Just shifting into 1st (which there is usually a clunk) and driving out of my neighborhood the shifting was smoother than it ever had been. I gave that oil change 5000 miles. Our trip that summer was the remainder of Route 66 from Amarillo to Santa Monica. Going thru Needles it was 106. Never did the shifting get hard or cluncky. My Valkyrie has 108,000 miles and I also bought an 05 Wing which shifts smooth as silk. Best oil ever!!

Always Amazes Me...

From the first time I used Amsoil to present day use... I always am reminded about how good your products are. First time I used Amsoil in my 1996 Lincoln Mk VIII, it had a sticky valve and always made a tick tick tick noise...always. After two years of driving That Lincoln i tried Amsoil and 5 seconds after startup... that tick went away. Plus mileage went up a few points.

Fast forward to my first oil change on my 2013 Honda F6B motorcycle. Bought it used like most of my vehicles and I was getting around 34-36 mpg. I bought the Amsoil for Metric Bikes 10-40. First tank of gas I went up 4 mpg. I have been riding motorcycles for 40 years and I ride out in the Texas hill country pretty aggressively for fun. But how nice to get an average of an extra 20 miles of driving range from the same amount of fuel.

I have been running this oil ever since 2010 in my Kawasaki 900 Motorcycle. I have ran it to at least 6000 miles between changes.The 900 is a smaller bike and I really have put some rugged miles on it. I am very impressed with the quality of the oil, and will always use it in any other bike that I may acquire.

The only thing I use

I use Amsoil in everything I own with an engine. It goes in my new car, my old bikes and my lawnmower. I use it when I service someone else's engine. I get extended oil changes in everything so it's less expensive than the bargain stuff from the local auto store. I use the Ea filters whenever possible because they filter smaller particles which means my engines last longer and run cooler. I can't think of any reason to use anything else.

Excellent engine life

I've been using Amsoil 10W-40 motorcycle oil in my street bikes for over 15 years. I had a CBR600 with 95000km that used Amsoil from the first oil change. That bike had a spirited life with lots of commuting and many high paced track days. At that high odometer it had great dyno numbers, didn't burn any oil, and had never had any engine problems. When I was replacing my clutch at about 85000km I inspected some engine internals and it was amazing how clean a free of wear everything was.

Great for my road bike. Great for my race bike.

I personally run AMSOIL 10W-40 Synthetic Metric Motorcycle Oil through my road bike for the street and race bike at the track. This oil has always held up very well for me and always seems to outlast the filter. I swap it out every time I make a filter change (just out of habit), but it always looks as clear as when I first put it in.

When racing, I'm always on the throttle and make very hard downshifts (probably worse than I should). I have yet to see this oil deteriorate on me, even when stressing a motor very hard. I couldn't be happier with its performance so far this race season.

I recommend AMSOIL products to everyone I come across, whether on the street or at the track. As long as they continue to make high quality products, I will continue to do so moving forward.

It's really good stuff.

If your on the fence about using synthetics in a wet clutch motorcycle, no need to worry. I purchased a new goldwing 1800 in 2001 and started running Amsoil at the first oil change. After putting 100,000+ miles on this bike, the clutch was just as sound as the day I rode off from the dealership. No slipping, chatter, sticking or any clutch related issues at all. I sold that bike a couple of years ago and it continues life today as a trike with the same clutch that came from the factory. Now belongs to a coworker and has a tad over 140,000 on it. I now have a 2014 gl1800 using Amsoil as well. I found it to help with less overall engine noise, paticurly the high pitch whine common to the 1800. Shifts were smoother and less clunky. Mileage may have improved a bit but hard to tell with the way I ride. I may be pushing 60 but I still have a very flexible right wrist. Didn't have to ponder about what oil to use. I'm sold on Amsoil and until something better comes along that's where I will be. No worries and no regrets.

Switching from Motul 5100 Semi Synthetic

The Motul 5100 Semi Synthetic is a lot more viscous than the AMSOIL. In terms of performance, I have found any oil change be it a car, motorcycle, boat whatever etc always feels like it has a better “Get up and Go” after an oil change. The main reason I switched to the AMSOIL full synthetic is that full synthetic SHOULDN’T break down as quickly as a semi or conventional oil. THIS is where the extra $$$ for the AMSOIL should come into play. That being said it is hard to know when the breakdown period is with any oil, and the trick (in my eye) is to keep on top of regular oil changes in order to prevent breakdown from happening. After 3000kms the oil that I drained out of the CBR yesterday still looked not to bad and smelt okay. I think the bike runs a touch smoother with the AMSOIL because of the viscosity, it’s that much thinner of an oil, and the bike seems to idle lower and run more freely than with the Motul Semi Syn.

I have always heard good things about this product along with Mobil 1 Full Synthetic & Royal Purple…

The customer service and location of you guys makes this a smart choice!

Thanks for making the switch so easy, see you in another 3000kms.

Using AMSOIL 10W-40 motorcycle oil in my 1985 Honda Goldwing

I am very impressed from the first few kms to now. The response of the engine has greatly improved with this oil change. I don't think the bike has run this good in quite a while. I'll be definitely calling again to arrange more purchases of oil for this one.
