this oil is great stuff, I use it in my vintage bikes, a 68 BSA and a 70 triumph Bonneville. It works good in these bikes.

Have used many synthetic oils. Amsoil is top notch. Far quieter than other oils as far as engine noise.
Amsoil Tranny fluid outshines the competition with smoother shifting and ease of finding neutral. If you ride a Harley, you know what I'm talking about.

This oil makes the bike run smoother and quieter. I like that I can use it in the Engine, Trans, and the Primary. I use Amsoil in all my vehicles. Nice to change oil and filter once a season and still get great protection.

Becoming a preferred member has made this top grade oil not only affordable, but because of its longevity it is a much better value than other synthetic brands!

All my motorcycles run this product. One bike has 80,000 Kms on it and it is still an untouched strong machine. They all run cooler due to less friction. The trans shifts so smooth with the synthetic oil.

I have a motorcycle repair shop and I am switching to Amsoil. Superior product and better priced. I won't use anything else in my Harley-Davidson. Another advantage is I can deal directly with Amsoil, can't do that with other manufacturers. Overall a fantastic product and company! Order online and it comes to your door.

I use Amsoil V Twin 20/50 and the Amsoil Signiture Series in my cars. The motorcycle oil has saved my engine on a trip from Tennessee back home to Pennsylvania. Engine temps and oil temp was well over 350 degrees. Normal engine oil operating temp is 150/180 degrees. When the problem was discovered and repaired, I found the engine to be in good condition. I believe it's only because of Amsoil that my engine survived.

I've tried Royal Purple, Red Line and HD amongst others.
There is much less engine noise and transmission "clunck" than there is with the others.
Engine seems to run cooler also.

Been back and forth trying multiple products... i.e. Royal Purple, Mobil One...etc. Amsoil slams them all. All wear graphs are different, but Amsoil is always at the top, regardless of where the others place. Go twice as far without changes or worries... its a no-brainer.

I like the 20w-50 V Twin Motorcycle oil very much. Although I do not ride a 'V-Twin' I do ride a BMW that is air cooled and find that it runs much cooler and smoother than the oil that came with it from the dealer. Presently the bike has about 90k miles on it and still runs great. I will continue to use this oil and the corresponding fluids for the transmission and rear drive.

When you add in the fact of extended service periods, that, my friend, is value.

I'm impressed how amsoil has increased my fuel mileage in my Harley. It not only increased mileage but also has reduced engine temperature by more than 20 degrees. I have a oil temp gauge on my bike and for years I used other well known synthetic oils. No other oils reduced the temperature which will result in performance and fuel economy.
