I switched to AMSOIL in 2006 and haven’t used anything else since. The V Twin 20w-50 is what I use most of and it performs as AMSOIL described. I have 5 Harley’s and 2 Chopper’s and I only use AMSOIL. I ride with confidence!!

Great product , engine runs great improved fuel mileage , clutch is smooth, no shifting issues

I’ve been using amsoil products since the mid 80s and will continue to do so for the rest of my life. Great wear protection.

I was told by a friend to try amsoil its the best oil I've used and ill never use anther oil in any of my vehicles

I use this oil in my 2004 Victory Vegas and it has smoothed out shifting. I would definitely recommend it.

I have been using Amsoil in my Harleys for the past 15 years. I am meticulous when it comes to keeping my bikes running and Amsoil has always been my go to. Great product.

I have an '07 Kawasaki Vulcan VN2000F, the only complete oil I'll run is the AMSoil 20W-50 specifically designed for V-Twins. I also couldn't be happier with the service provided. I've ordered a couple of times and both times I've gotten my product the NEXT day! THANKS AMSoil!!

I don't usually write product reviews, but this product deserves an exception. I have a 2001 Harley Davidson Ultra Classic. I bought it new and started using Amsoil 20W50 VTwin at about 30,000 km. The bike now has 566,000 km and is still running great. It would not be true to say the engine has had no work in the last 20 years, but nothing that was done was related to the oil. The lower end is original. I also use this oil in the transmission, which is original except for a bad shifter shaft bushing and the primary. Most of the primary is original as well although I did change the clutch plates for the first time at 542,000 km. They were still in serviceable condition and I think they would have lasted several thousand more. I attribute this long life to strict maintenance and the use of superior products such as the VTwin oil.

First time user of this oil on motorcycle. It is difficult to find this particular oil in local parts stores where I live (Santa Clarita CA.). I found ordering from you online was quick and easy.

only oil I trust in my bike for 15 yrs

Use dedicated oils in crankcase, trans, and primary. 95 Evo FLHTC, 60,000 miles,rejetted carb, EV13 cam, mufflers. I can get oil through my preferred customer account, or also available at my Harley dealership.

My harley runs cooler with this oil

My buddy BA recommended this product and I am extremely pleased.

I had been using Amsoil since 2001 in my Motorcycles and will not use anything else. This has proven to be the best there is.

Great quality, dependable

Used this in two of my harleys Great product

Harley runs about 15-17 degrees cooler than other outrageously priced oils that say they are the “best”.

My Harley has used Amsoil since new at 90 thousand KM the compression is as close to what it was new ,transmission gears and chain show no wear at all mileage dictates it should need rebuilding but not even close Amsoil in motor, transmission-and primary have payed off big time I won’t use any other type of oil !!!

Performs as advertised. Ride 1600 miles in 7 days on Harley. Ran flawlessly

What can I say...this is such amazing, good oil better than any other ordinary conventional oil out there like SYN 3. Don’t take my word for it. Try it and use. You’ll feel the difference. Thumbs up!!!
