Customer Ratings & Reviews

Good, solid, stable oil for my bike. I wish there was a "three hole" kit for when a man wants to change crankcase, primary, and transmission oils. Click one button and checkout. But I guess that's really more of a complaint about the website.

When one isn’t enough. Go big or go home

My 04 Harley Davidson FXDI Superglide runs great with your oil.I can hear and feel the difference. I will definitely continue using Amsoil products.

Since using you oil on my 103 I noticed when the bike got hot it still had oil pressure . I used Harley synthetic oil from purchase oil my 2013 when it got hot I had 0 oil pressure obviously your product is better

I use this oil in all three Harleys and works great, bikes run cooler and shift smoother. Very happy with this oil.

I have been using this oil for decades. I will continue to use it for decades to come.

Great product, but all the adds say free shipping over but I did not get that I was charged shipping

Excellent oil, Excellent for my Harley very good.

Engine feel less friction

I don't use anything else in my engine keeps my engine cooler and doesn't loose viscosity I change my oil every 5 k and it's looks almost new still unlike others which would be black

I ride a Harley and I ride hard. I've been using HD oil for years. After research I decided to try Amsoil. I did a 3 hole change. My oil temperature dropped 25 to 30 degrees cooler. Seems smoother. Very impressed.

Amsoil in my engines make me feel good….3000 miles since last change and oil looked new

This is the only oil that goes into my bike once the first maintenance is done.

I've been running this oil in my '21 Indian Roadmaster since new. Now at 42k miles and no problems at all. I can buy this oil, a high quality WIX oil filter, and get the copper crush washers in bulk cheaper than I can buy the semi-synthetic Indian oil kits for. Much better quality for the same cost.

Just bought a used Harley that the previous owner used Harley Syn oil in. I immediately order Amsoil Syn motorcycle oil. Boy did it make a difference. Can’t wait to change the primary and transmission to Amsoil products!

I have a 2006 Road King. I switched over from Amsoil 20w-50 to the straight SAE 60w because of the Heat here in Florida. My bike runs cooler than before, and I recommend this product very highly

I've been using Amsoil in my Harley sence day one.It gives great engine protection compared to other brands on the market.I will not use any other brand in my Harley but Amsoil.

Great product great service.............

Love the fast delivery. This is excellent oil and weight for hotter climates . If your coming from here ( Prince George) and heading for say Kelowna on extended stay , it is a perfect oil to use and protect your engine .

I have been an Amsoil user on my vehicles for over 20 years, when it comes to my two motorcycles, it is the ONLY oil that has ever been used on them, my older bike has over 80k miles and still runs great, my newer bike has over 45k and still runs great. Quality and price wise in my opinion Amsoil is #1!!
