Customer Ratings & Reviews

Amsoil,or as others call it snake oil holds up to the conditions I put it through long steady rides in hot weather,onto town and stop and go traffic ,have Sent it on for to be checked out for motor e wear and other signs of wear always comes back favorable. I tell all who will ask good stuff get some

My Harleys run cooler n smoother in the engine plus power lever feels more torque … I run nothing but ,

Good quality oil

I thought there was better till I tried this oil out on my softail ,I can feel and hear the difference,,smoother shifting and the engine is quiter The engine is quiet but the pipes are still loud as heck but thats the point RIGHT !!!

Very good oil. The motor feels like it runs better. I will keep using this oil

This oil did what they said it would. It's hard to find a product that really works like they say it should. I will keep buying this over an over again .I definitely will recommend this to everyone!!

Great stuff

I believe this oil is everything they say it is, my 114 m8 runs great on it quieter and smoother. Will be using the primary and trans. Oil also It gives me piece of mind knowing I'm running a superior oil in my Harley!

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
