Customer Ratings & Reviews

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.

Great performance and protection

This is another excellent product from Amsoil that I use and recommend to everyone I come across. I’ve tried several different brands and then I found Amsoil and will never switch. I use this kit in my Harley and have used it in several friends bikes as well. Thanks for another great product Amsoil

The florida heat plays a big role in our motorcycles so i always turn too the proven performance oil on the market Amsoil gets my vote 100% of the time.

My oil change kit was delivered to the door with everything I needed, including a disposable funnel and a pair of protective gloves!

Such a great product for my 2001 Harley Davidson Sportster XLH 883, with the best service. Thanks!

Like the products Over night delivery Hard to beat

Great oil , it is the only oil I use in my Harley Hide hard run cool

Excellent oil

Excellent oil

Everything you need to change the oil in your bike. Gloves, oil change reminder sticker , paper funnel, and o-ring for drain plug.

I use this oil in multiple bikes from Harleys to Hondas and yamahas. In the area I live, this oil works perfectly, its nice to only have to keep 1 type of oil in stock for regular oil changes. Although it does say this oil is good for all 3 holes on a Harley, I only use this oil for the crankcase.

for the cost, hands down the better choice.
