Customer Ratings & Reviews

Delivered promptly right to my door in about a week. Still waiting for the gear oil.

I always run amsoil in my buells and my harley. But recently picked up a 2005 DL650. So i ordered wix filters and amsoil for her. And she starts much better when it is 4:30 in the morning and still 28-34°F degrees out. Also seems a little quieter on valve train noise when at operating temp.

I could tell a huge difference when I switched to AMSOIL. I will never use anything else in my motorcycle.

By far the best motorcycle oil I have used in 50+ years, bar none

Great product but shipping company used is terrible. Will stop using Amsoil if they continue to use UPS. Products arrived again with oil and filters all over my drive way. UPS is notorious for destroying the shipping boxes. I know, as I worked at UPS. Terrible shipping company.

It poured like oil should.

I use nothing but Amsoil products... every engine I use Amsoil in runs much cooler. that tells you a lot!

Runs , purrs wonderful!

Can't say enough good things about Amsoil's synthetic. It seems to have freed up a few more ponies and I hooked.

I use this oil in my 1700 cc bagger, smooth shifting, and no engine noise, Best oil there is.

I have been using Amzoil for about 8 years I started with my Suzuki Vstrom 650 in 2012 and have used it ever since my bike has 109000 miles on it and still runs like a top I am sure that using Amzoil has extended the life of this motor.

I am an Amsoil believer. I think they make the best products. I change the oil in my Gold Wing motorcycle once a year using their Synthetic 10W40 Motorcycle Oil. I have done that since purchasing the bike new. Now, with over 130,000 miles on it, the engine continues to run like a top.

Oil is a hard thing to review, once it’s poured in the engine you really don’t know To much about it. But, you do notice with amsoil it shifts much smoother, runs Cooler, and the rpms fly up faster. I use the proof and specs of amsoil when deciding what oil goes in every vehicle and motorcycles I own. I feel very confident when this or any amsoil product is in my engines. When I drain the oil After I feel it’s life is done it still comes out a golden color. I have been a mechanic for 37 years and I will not use any other product other than Amsoil.

Smooth shifts and smooth engine.

I use Amsoil in all my engines it is the best

I have a 2007 Suzuki 1250 Bandit S that I bought new, it has close to 100,000 miles. As a commuter and tourer the Bandit is heavy on the torque and lends itself to spirited driving. I have used other name brand synthetic oils in the Bandit but always changed oil at 1600 to 2000 because of annoying "clunky" shifting. Upon first using Metric over 10 years ago I found myself changing oil at the 2500 to 3000 mark only because it made me feel better not because of shifting issues. I flip flopped a couple of times with other brands and the Clunk would come back around 1600 miles. Amsoil is the only oil that holds up to rigors of my Bandit.

Best oil you can buy for your motorcycle, shifts quiet and smooth, very best oil.

Replaced factory oil with Amsoil full Synthetic at 700 miles on my Z900

I've owned many cars and motorcycles over the years and lived in cold as well as very hot climates. In the past, I've had engines go bad, but for the past 25+ years I've used Amsoil and had rust and other things that caused me to sell a car, but the engines have never failed.
