Customer Ratings & Reviews

Brought the bike to the dealer for recal work. Unfortunately, they drained my Amsoil and put in BMW synthetic. On the way home I notices clunky shifts like a Model A. Waiting for my Amsoil order to arrive for a buttery smooth transmission.

I'm not racing, doing high miles, or doing oil testing, so all I have is my subjective impression. This seems like very, very good oil.

Amsoil products are always top notch and outperform expectations. Picked up the 10W-40 for my niece's Suzuki GSX-R 600. Engine revs smooth as silk and she zero issues with shifting or clutch engagement.

Changed over to this oil in a 50-year-old Honda 750. It had always been chattery when shifting into gear after winter storage with conventional motorcycle oil. Once switched to over to AMSOIL the clutch operated smoothly, and shifts were quiet and uninterrupted in flow

I have 84,000 miles on my bike and she runs like a top everyday

I use it in my 2016 Spyder F3T Limited and like it a lot. I recommend it for all motorcycle and 3-Wheelers!

I think this is some of the best oil out there, that being said there online cost calculator is horrendous. They seem to be unable to tell you what tax is going to cost depending on your state which is minor but the real problem is they try to bill you 3 days later for " hazmat costs" if your state requires it let me repeat that 3 days later which they don't show you a list then tell the customer to go find it for themselves. Then it takes 4-5 different customer service emails about the same subject to get corrected. Very irritating for what should be a easy fix. So 5 stars on the oil 1 star on there ability to tell you what you are actually going to be billed. To be fair they did waive the hazmat cost "this 1 time" but it still doesn't look like they fixed the problem.

Smoother shifting, better fuel economy

I use this oil in my 2020 Triumph T120 and 2021 BMW K1600. Both bikes shift well with good clutch feel. I do believe my 1600 runs a bit cooler on hot congested traffic days. Neither bike has a consumption issue. The transmission and engine oil are common on both bikes. Too that end I’ve never noticed any metal on the magnetic sump plugs. I also use Amsoil 80w90 in the final drive of the Beemer. After initial change I haven’t seen any shavings on my drain plug.

I ordered the oil change kit with the wix oil filter for my 2009 R6 the oil was a perfect amount but the filter does not fit. The filter threads on great but it hits the shift linkage preventing the shifter from returning to its proper location when not shifting.

This was the easiest Purchase using PayPal-credit I've ever used 😉

I use amsoil in my motorcycle as well as 5 of my friends bikes. We are all very pleased with this oil.

I Love it I use it I don't ride without it So buy it You'll love it to if you love your bikes thin you must run Amzoil, because it's the Bomb

It's been used in every motorcycle I've owned, both Harleys & metric. The latest one being a 25th Anniversary Busa. I immediately noticed an improvement in shifting.

Beeb using in my 1990 Goldwing that now has over 325,000 km on bike. Transmission shifts nice and smooth, oil great for Long distance

I have been using Amsoil since 2012. I’m now using it in my 2024 Triumph bobber. After my first oil change I noticed smoother shifts and less valve train noise. I will continue to use this product in everything I own. Great oil.

I have a Yamaha R3 and after switching from the oem oil to this I felt an immediate difference. So much smoother and the vibrations from the bike decreased quite a bit.

I had used Mobil 1 in my GSX S1000 GT before my last oil change. I had been reading reviews and kept hearing excellent reviews about Amsoil, so I decided to try it. My engine runs quieter and transmission shifts much smoother…in fact I noticed the difference in the first few minutes of running it!! I have already recommended that the group I ride with start using Amsoil over whatever they had been using !! I’m sold👍🏻

I am a long time Amsoil user. Never had an issue with any product that I have used. Highly recommend Amsoil if you are thinking about a high quality synthetic oil.

This is a great product. We use it in all of our motorcycles. Nothing but the best.
