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.

Just moved past the break-in point on my BMW R1200R at ~14k mi. where it's time to go FULL-SYN - With doubts about the BMW spec of 5W-40 having more modifiers for cold weather-related starts (which I don't need in Cali), and being WAAY more expensive...I went with this Amsoil 10W-40. Sure-enough, the engine just "purrs like a kitten"! - Yes, VERY Happy!!

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. Most manufacturers have realized the benefit of a easy pour design and have incorporated it into their large capacity containers. That is one feature that I miss...

I started using Amsoil about twelve years ago. I use it in all of my vehicles, car, truck, motorcycles, and small engines. Cost is high and getting higher it seems with each order but I need for my vehicles to last for another decade maybe more now that I'm retired. I really like that for me it means one oil change/year.

Have used AMSOIL for the past 15 years on my 3 motorcycles. The bikes performed flawlessly and smoothly. The big difference to me was the smooth shifting when using AMSOIL. The engines also seemed to run a lot smoother.

Honestly I like it better because it helps cool down my bike and did lost a much longer time than other brands i used in the past
Reviewed by ssevy:
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!

I always buy quality, but I also like a great price and I feel like I get both with Amsoil. My bikes always shift better when I run Amsoil, why I don't know but the smoothness of the transmission is always noticeable whenever I run Amsoil. Transmissions are hard on oil and that shows me Amsoil is doing its job!

I use amsoil exclusively in my cars and motorcycles. Used their products on my Porsche Cayman S rebuild as well (assy lubricant as well as brake-in oil) and its flawless. My race motorcycle oil comes out nicer and with more remaining viscosity than anything I've tried. Beware of expensive ester based bike oil. Lots of hype with little goods delivered.

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.

Use this in both our bikes. Last summer on our annual road trip we got caught in rush hour
traffic with a major accident. lots of stop & go 5 to 30 yards at a time, I'm pulling a trailer, wife has extra 100 lb. of luggage (2hr to go 20mile/32 km), all this in 100 deg. Fahrenheit temp.
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 just changed the oil that came with a used BMW R1200C that I recently bought and so far it is running as smoothly as ever. Since this is the first time that I used the oil it is a little early to judge it but having used Amsoil in all of my products for years I am confident that it will be just fine.

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!
