Customer Ratings & Reviews

Good for 5000 miles. Keeps the engine running smoothly.

This Oil Works great, When On the Run For The Wall 2025 on my 2020 Harley Road Glide Limited and loaded it down and drove over 6800 Miles on a fresh oil change, and Oil still looked dam good. Only oil I will use on my motorcycles, Cars, Truck and boat. Love It Thanks for a great Oil

Great delivery time Great oil

Have had no problem with the oil very little oil burn off between oil changes (6000-8000km)

Great product does keep engine heat down on summer days

I changed from HD Synthetic Oil to Amsoil and I'm glad I did. After 5000 miles compared to the HD oil, you can visually see the difference. HD oil has always come out black and you can tell that it's lost a lot of it's life. I changed out this last go around from Amsoil to Amsoil and there was still plenty of life left in the oil. The difference in color and feel of the used oil was a big difference from the HD oil. Definitely recommend this oil. I started running Amsoil in all of our vehicles a few years ago.

I use this in all three of my Harley’s. It’s a better way to not have to open 4 bottles of oil when doing oil changes and saves a little money by bulk purchase

Best oil. Get the kit.

Best oil I’ve ever used. This oil lasts and I have never had an issue with this oil. Beets other brands by a long shot.

I have been using Amsoil since 1995 when I bought my first Harley. On my third Harley and still using Amsoil. Have since just like a favorite hot sauce I use that s?!t in everything. We have a 2013 escape with 169,000 miles, f-150 with 101,000 miles and a Kubota tractor with 1300 hrs.

The oil is the best, but they sent me the wrong oil filter with my order so recheck your order before they send it to you

Love this oil, have always had great success with it!

Excellent product at a reasonable price

This is all I run in my harley 103ci. Never a worry.

Great product runs cooler quick shipping

I've been running this in my 2012 harley davidson and it seems to like it holds good oil pressure i highly recommend

excellent product. Have used only Amsoil over the years in all my Motorcycles and found it to be the best product bar none.

I have owned motorcycles all my life. I've used Amsoil, Mobile 1, Gastrol Synthetic, Harley Davidson Screaming Eagle Synthetic, Pennzoil Full Synthetic in my bikes. There is no oil that performs and outlasts more than Amsoil. Even when its time to do an oil change, Amsoil is still performing like it's new. I exclusively use Amsoil in my motorcycles now. Thank you Amsoil.

I've been using Amsoil for quite a few years with great results. I ride a 2015 Harley Davidson Roadglide and I'm proud to say still going strong at 135k miles. I had to replace the motor at 99k but the dealership mechanic told me that's pretty good miles for this motor. I'd recommend Amsoil for anyone who wants to maintain their vehicle for long term ownership!

Fast service, just switched to amsoil
