Have been using the Amsoil Metric 10W-40 for the last 4 years on my Yamaha V Star 650 and now on a Yamaha V Star 950 - I originally used Yamalube 10W-40 on the 650 but didn't like how loud the engine / valve train sounded so shifted to Mobil1 4T 10W-40 - it quitened down a bit - after 4 oil changes I decided to give Amsoil a try - again the sound decreased - all anecdotal but indicating less engine wear and tear - so I continue using it to this day - found the same noise level decrease with the 950. Another great benefit of Amsoil - is online order and delivery - basically the same price as dealership Yamalube and delivered to my door within 3 days and never out of stock. My one knock against Amsoil is the oil filter cost - $29.20 - I use a comparable filter - Hiflofiltro HF-204 @ $9.42 per filter with free shipping - c'mon guys - give us a break.

2 days after I order the case of oil , They come with a sale buy 4 litres get 1 for free. Phone and Amsoil as I’d there nothing they could do .🥵🥵

I've been using this product for years. Great product never have had any engine or clutch issues since I started using.

My friend & I used this in her 2021 Suzuki V-Strom 650, and strongly recommend it!! Delivery was fantastic upon arrival!!

Used this in my 2022 gsx-s 750 for my first oil change after break in. Been doing research and from work of mouth that amsoil is good stuff, and it defiantly is. I will be using this throughout the engine life of my bike. Not to mention the website is great to use with kits made up vehicle specific. Delivery was amazing also, ordered on a tuesday afternoon and was at my doorstep thursday. Thank you amsoil, keep it up!

Great stuff as always! Good filter too. I use Amsoil in all my vehicles

Oil seems fine. Called the company though, to check on what's best for an older (1997) dry clutch motorcycle (Ducati 900 SS) and the tech guy I spoke with wasn't terribly cordial--almost like I was asking a stupid question. So that wasn't great, but the oil seems to do the job.

The oil lubricates and does it well

I’ve been using this oil in my 2002 Triumph Sprint ST for over twenty years. It’s got 120,000kms on it now and still runs grea. Thanks Amsoil.👍😂🏍

I’ve been using this for my 2015 Kawasaki Versys 1000 LT it’s is great at keeping things lubricated and running smoothly. Temperature here can be 95+ on some of the roads here in the summer. I trust the oil. I just did an oil and filter change and my engine holds 4 qts with the filter. This time it took the entire jug and a half quart of leftover bottle of the same oil to bring it up to the normal level. I am positive that the gallon jug I purchased didn’t have the entire 4 quarts in the jug. Maybe the jug was a tad smaller or the markings were off but I did need to add an additional half quart to bring to the normal 4quart level in the sight glass on the engine.

I ride a 2002 Honda Saber 1100. I have used Amzoil in here for two years. The Saber is notorious for noisy lifters. I have tried different oils and weights to quiet them and Amzoil is the best. This a secondary benefit the real benefit is its lubrication. Two years and 16000 miles ago I lost oil and pressure and ran the bike for some time before I knew what happened. I was concerned that irreparable damage may have been done, but I fixed the leak an it is running fine after 16000 miles. I believe a regular oil wouldn’t have given me this result. I really believe Amzoil is worth the cost and won’t run anything else.

i use your metric oil in my can am and my suzuki motorcycle , they both give me great service ,use no oil between changes and engines stay very clean . i can say the same about my three toyotas that i use a regular 10/30 oil i even used your atf when servicing the toyota tranmsmissons also great stuff , love it .

Running AMSOIL motorcycle oils for about 20 years has given me peace of mind to never worry about engine protection, running one year drain intervals, or any other oil-related issue.

Very satisfied

Perfect for Yamaha

Been using this in my GL1800 for the past 5 years. Quits down the engine and keeps the engine running smoothly and keeps the wear down.

Been using amsoil products for years in 2 and 4 strokes. You get exceptional life and minimal wear.

A great lubricant engineered for my engine. Motor actually sounded smoother at first use. I’m sold !
