Customer Ratings & Reviews

I trust and use Amsoil Metric in my street bikes and race bikes. Exceptional film shear strength under load (confirmed post race cam lope inspection).

I run this oil in all my bikes and I’ve looked at all the clutches in my bike this stuff works great

10W-30 is the OEM and recommended oil for my Honda Monkey 125, so very glad AMSOIL provides this oil. Kind of a "rare" weight oil in wet clutch compatibility, so very glad I get it from AMSOIL as usual and I don't have to drive to a dealer to buy Honda oil.

Ams oil is the best hands down. Race oil 🏍🏎

I start using Amsoil metric oil 2 years ago on my 2015 BMW S1000RR. I do both Street and track on my bike and never had a problem with clutch or engine performance. I will continue to use this oil for as long as I've have my bike

I have run Amsoil in my 2005 Suzuki V Strom thousand Sense new have over 108,000 miles still runs strong doesn’t burn any oil or smoke in the plugs are all clean

Great products been using them for years in my Harley and added a Honda Goldwing. Great, fast delivery too! No need for Amazon, Amsoil all American.

If you have been debating on weather to use synthetic oil debate no longer. Amsoil is by far the best and I would never change. The first time I put this in my 05 Goldwing within 2 blocks I could really tell a difference in the shifting. It was smoother and quieter than ever. Then I had 3 other Goldwingers try it and 2 of them became distributors also. Then I was not sure if I could use it in my 2018 Goldwing DCT Tour and Amsoil said that was fine. I put in the 10W 30 and what a difference in shifting. With the DCT automatic you do not have to RPM match when shifting. It has 2 clutches and it slips when going into the next gear and matches RPM for you. When I put the Amsoil in the slippage was not as much and at every shift you could feel the pull as it hit the next gear. Amazing! I use Amsoil in everything I have. Great Product.

Best Lubrication! Runs Cooler! Shifts smoother! I have been running Amsoil 10W40 MCFQT in my 2007 Honda VFR since the first oil change. Still Runs perfect! Change it once a year and forget about it!

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!
