Customer Ratings & Reviews

I just recently switched to AMS oil for my 2018 Harley 114 from their signature Syn3…so far, so good…the bike seems to love it and the filter was an exact fit…Ive also noticed a little less chattered from the top end that the M8s are notorious for having (sewing machine noise)…so that’s a plus…

This is a great product! You can tell the difference between most oils. it's either to thin or to thick but with amsoil each and every different type has its own volume to it. Highly recommend all of their products!

Outstanding motor oil.

2nd time purchased for my 2006 Victory Hammer. Runs a bit cooler and quiets down transmission noise.

The most asked for oil to be used in the industry. I use nothing else but the best and this is it.

I have tried several of the "premium" motor oils and I always come back to Amsoil. As an aside, if you want a slick functioning transmission use their transmission specific lube. I thought something disconnected in my trans it shifted so smoothly and quietly. That is the first time I could ever say that. My H-D has about 40k miles and shifts better than new.

Happy with purchase. Fast shipping. A+

Fast Shipping & cheaper then my local Auto Parts store

I've used this oil in three of my Harley v twin motorcycles. Motor,Primary and Transmission. Each bike had 34,000 plus miles on them. I never had anything Go wrong with the transmission, primary, engine.

Great kit , includes everything needed for the oil change , seems like good quality chrome filter and an O-ring included for the drain plug . Definitely will be ordering this again .

Always fairly fast shipping. I ONLY use Amsoil in my Softail Custom.

Order the oil filter and o ring for my Harley. Few days later it’s on my front porch. I’d give 6 stars out of 5 if they came and changed the oil for me! 😜

Recommend amzoil for any bike

Great pop for my Indian chief

Fast delivery. Great products.

Some of the best oil at a fraction of price compared to other recommended brands

Great way to get what you need for your oil change it all comes in one box with a bonus, a new O ring for your drain plug, 👍

I've been running this oil with no oil cooler on my '08 Street Glide for three years with zero problems, In some very hot weather (100°+) on hot black top. I change oil every 3000 miles.

Very good are you probably the best on the market for my Harley Davidson? I run a one 35 in.³ twin cam motor 170 to 180 hp motor. I’ve been running this oil for years and I’ve been getting a lot of miles out of my high performance twin cam motor. I recommend this oil to everyone old is a lot cheaper than motor.

So far so good, i typically run conventional but decided to give into the hype, cant say its better than what ive used before, but it certainly hasnt hurt anything.
