Customer Ratings & Reviews

Put 48K hard miles on my 2023 Road Glide Special and had the oil analyzed every 10K miles. Changed oil earliest 3300 and most 6500 miles and each time analysis showed oil still 100% and no signs of wear. Tore bike down for CAM, Lifter, Adjustable pushrods and negligible wear or signs of use. My M8 runs hot from 334~374F and I worried about long term wear but comfortable that AMSOIL in all three holes kept my bike like new.

As usual, easy transaction and fast shipping!!

I like it is good product no complaints

Très bon produit et prix

Game changer for my Trans on the HARLEY

Simple oil change kit for vtwin.. only nitpick is Harley has a larger capacity oil filter for the M8

Using it in my bike now instead of HD. Looks like the bike likes it as much as I do

Great product comes with everything needed funnel and gloves as well very convenient

My wife has 130,000 miles on her 2020 Streetglide with zero maintenance issues. The V-Twin Kit makes the many oil changes easy. I like the fact they now include gloves and the portable funnels which come in handy on the road trips.

Best oil for my Harley I highly recommend!!!

I used Amsoil after my bike kept getting super hot in the Summer months. Wow, what a difference! My Streetglide is now smoother and cooler than ever. I’ll continue to use this for as long as I own my bike! Thanks Amsoil!

I bought a new Indian. Of course I had them change my oil the first time, but noticed my valve trane was way too loud to say it was normal so I went back to my old staple, AMSOIL, now it’s quiet as a kitten and my new Indian will from here out run only AMSOIL.

Excellent product and speedy delivery.

I am a big fan of Amsoil and run it in all my vehicles, motorcycle, ATV. I love the protection/performance I get from their products. Lightening fast delivery and the best products. I also like the garage feature so I can accurately see what my equipment uses and check dates if needed.

So how do I say I'm NOT really into much about the science of oil seeing that I live mostly under a rock and amongst them pretty much up here in Nor. Ontario! However that said it somehow derives from dinosaurs is my theory but, what pleases me and my bike I'm sure is the fact that living up here is often not convenient to purchase motorcycle oils per say and when you do find stock you don't always get all the amount in one stop that you need nor do you get other additives a brand will sell. Well I went out on a limb and ordered oil "ONLINE" which I'll say is definitely a FIRST and what do ya know I obtained not only all the oil-filter-and gasket but my primary and clutch oil too all in a convenient box shipped FAST! I'm a fan of THAT and not only this but the price was pretty hard to resist too! The oil though is very oily and pure lol!

An excellent, cost effective alternative to Harley-Davidson's Syn 3. I use AMSOIL 20W-50 Synthetic V-Twin oil in my engine, transmission and primary.

Change oil in my Bikes every fall before storing them for winter. Amsoil in my opinion best oil for a vtwin. The ordering process is very difficult. I respond through an email I receive from Amsoil. Which I receive almost every day. But even though I respond to an email send to me I have to go through an impossible difficult password jungle to gain access and place my order. Just frustrating. I don't understand. I respond to the email send to me by you. So how come I can't just place an order easily. Why so difficult? And why does a company blow up Your email after you order something? I don't have time for any of this. Just 4 quarts of oil and a filter for two vtwins once a year in the fall. That's all. Should be pretty simple.

Riding in the desert heat, I only trust Amsoil to hold up. I’ve also done 1000 miles a day multiple times. Best oil for your V-Twin.

I had my motorcycle engine rebuild. Ran it for 500 break-in miles. Did my first oil change with Amsoil and it made a noticeable difference. The engine was a little quieter and the clutch worked perfectly. Changing the fluids is probably the most important thing you can do to extend the life of all your vehicles. Don’t skimp on quality !!!!!!

I've tried about every oil brand out there and always go back to Amsoil.
