Customer Ratings & Reviews

For years I used every major brand of motorcycle oil on the market on my Harley's and within the last fifteen years my Honda Goldwings. After changing over to Amsoil Metric, the Goldwings transmission shifted much smoother and quieter than any of the other oils including the Honda motor oil. It was such a noticeable difference that it was shocking. The right motor oil makes a huge difference.

1st time using AMSOIL products and was impressed with buying and receiving shipments on time and correct.

I been Driving my 1996 Honda Vfr750f for some years and been on many adventures on it. I currently have 60k miles on it. Like many Hondas its normal for some ticking noises coming from the valves and those noises to grow more with time and milage. I tell you I've used Honda oil and other Oils, but Amsoil really makes for a quieter ride, and smooth operation that's noticeable instantly. A friend of mine who's a licensed seller told me about Amsoil. Since then, I've been a big fan of it since. I can't say I write many reviews on products, but like my friend I really do believe in Amsoil products. Amsoil #1.

Used in a 1990 Honda Shadow. Bike runs cooler and quieter.

Spot on

Shifting on Yamaha MT-09 had become harsh. It had the stock oil and changed to Amsoil. The bike has much better shifting with this oil-not going back to the stock oil.

just become a member and get it you won't regret it

I have used Amsoil 10-40 MC oil Sience 1985 with no engine problems

Best oil by far for super sports.

I am a fan of Amsoil products so I tried the Metric motorcycle oil in my 1979 Kawasaki KZ650. I was unable to start the bike as the oil was too slick apparently to hold the starter clutch engaged. While I understand the oil likely works very well in other bikes I can't recommend it for vintage metrics, especially if they have the same or similar starter clutch as was used in the KZ 650. I drained the oil and replaced it with Valvoline conventional 4 stroke oil and after just a few tries the starter clutch began to engage again and the bike cranked and fired up as usual after that. I only wonder how the drive clutch may have acted because I couldn't start the bike but I would be worried it slipping as well. I don't think it is fair to say it is not a good product. It just wasn't good for my situation and I think Amsoil should at least avoid recommending this oil for these bikes. It was a lesson learned at a cost of 63.00.

first time using Amsoil so too early to tell if the oil is better than competing brands

Oil has been added to my motorcycle since I have purchased it 6 years ago. Pease of mind that it will take care of my engine for a long time. I have used Amsoil in a lot of my vehicles in the past with absolutely no problems.

The only I recommend. I tried all the others and there is no comparison!

Bought a 2021 Goldwing Trike with low mileage, had unknown brand of new oil with aftermarket filter. This is my first and last bike. I want nothing but the best for it ,so I can run it hard knowing its got a belly full of Amzoil !

I've been using AMSOIL products for a very long time. All my vehicles get the AMSOIL treatment. I use this oil in my 2024 BMW M1000R and my 2014 Yamaha R6. In particular, the shifting in the BMW has become much smoother, especially in finding neutral.

I won’t use any other oil in my vehicles, but motorcycles especially. Too many expensive things happen when you use poor quality oil.

In 2005, I bought a new Suzuki Vstrom thousand and I ran nothing but Amsoil in it for the next 15 years and 125,000 miles never had one problem with the bike and the person I sold it to is still riding the bike today

I have used Amsoil in my bikes for last 20 years, I have never had a problem!

I have always loved this oil. I’ve been using it for over 17 years for my BMW motorcycle and now for my Honda and have never had a problem.

Like it. Good for my bike
