Customer Ratings & Reviews

I recommend this product to anyone who will listen. I like to geek out over my motorcycle performance numbers anyway. So this stuff is at the top of my list.

Will reorder

Great product

Great product 👌

I have used this oil in my Harleys for years and have never had a problem with an engine due to lubrication.

I Recommend this all

I have a 23 Harley Street Glide and i have been using AMSOIL 20W-50 in all three holes since i got the bike and i love it. I love that i can just get the same oil for all three holes and be done but the main thing for me is the bike runs cooler and shifts out way better with AMSOIL in it. My bike is a Stage 2 114 and i ride it a lot and i ride it hard and AMSOIL has been great about holding up to the running that i do and i can tell that it is a great oil. i change all three holes on my bike every 5k miles and they are always clean and come back out the same color as when i put it in. Thank you AMSOIL for making a great product so that guys like me can trust that we are putting the best there is in the things that we take so much pride in.

Good oil used it for years no issues

Great product and great service

Great kit that makes it easy, comes with extras that make life better!

Once I heard this was one of the few oils left with significant zinc content my Yamaha cruiser needs I was sold. Ordered fast and delivered fast. A1

I’ve been using AMSoil since a little after it’s inception into the market and I will not go back to any other oils, providing AMSoil stays in business. I use it in all my vehicles, car truck & motorcycle. When I had a gas powered mower, I even used the used oil in my lawn equipment. Needless to say I’m a huge fan and when I did start using it, they had a replacement warranty on any oil related failure. I don’t know if they still have that warranty, but I’ll keep using their oil anyway. Also, when you’re a preferred customer the price is very competitive.

Better shifting transmission quieter running engine what's not to like about Amsoil

Outstanding, quality oil for those who want keep their motorcycle motors running longer due to specs that exceed manufacturers standards.

My go to oil for my 2010 Fatboy Lo. I like the product as I only need to change my oil once a year and my Harley really likes that oil

I've been running a 2022 Indian Challenger 108 Cu In V-Twin on this oil since new / break-in. The bike now has 15,467 miles on it. Indian Motorcycles use engine oil for the clutch / transmission and primary lubrication, as well as the engine, unlike another American V-Twin maker that uses separate fluids for each, so the demand on this oil is critical for Indians. I wouldn't use this oil if it didn't out-perform everything else on the market. Not only does the engine run quieter than when using other oils (including the manufacturer's branded product, and these engines are known for being noisy), the transmission shifts easier as well. I've used AMSOIL Signature Blend in my high performance cars and truck since 2008 with similar results. Using AMSOIL V-Twin Formula 15W60 was an easy decision for my Indian. It hasn't disappointed a bit.

i now have 196000 miles on my 04 roadking. useing amsoil products for trans and engine. went into engine once and never been in the transmission..all good

I was disappointed this time. The "kit" came with oil, and filter, but no o-ring for the drain plug as clearly pictured and called out in the description. No biggie, just a trip to the NAPA parts store and got the job done. QC at the assembly plant for the kit must've had the day off???? It would be good if there was a "Deluxe" oil change kit that included primary fluid and an extra qt of 20-50 to do the trans.
