My dyna loves this motor oil keeps it running smoothly

Been using amsoil for years can't go wrong!

Love it great product

I have all my Harleys on Amsoil along with my Diesel. Good product!

Swapped this oil into my 2019 Harley Ultra Limited for the 1k service. So far, I feel this oil quiets the engine down and makes it run smoother. I did not run this oil in all three holes since there are mixed reviews on if engine oil should be used in the primary and transmission.

I love the lubrication of the oil.

Using this oil lowers my oil temp by several degrees.

Many years ago, I read an article in Motorcycle Consumer News (similar to Consumer Reports), a magazine that does not have sponsors and is free to say what they think, that ALL full synthetic motor oil is superior to dino oil in motorcycles, particularly the air cooled ones. I've been using AMSOIL products in my cars, truck and motorcycles for decades and I've never been let down. My Harley Sportster 883 is supposed to run upwards to 240 degrees F in hot weather, especially at interstate speeds. On the hottest days the temperature gauge in my oil tank never goes over 205 degrees and on secondary roads, averages about 195 degrees. I don't have any other oil to compare this to but on the Harley internet forums, this particular oil is the top choice. I don't plan on switching just so I can compare products. I'm sticking with this oil because , "if it ain't broke, don't fix it". The Sportster uses this same oil in the separate (dry sump) oil tank for the wet clutch and works perfectly. The Big Twins use a heavier gear oil and AMSOIL is still a top choice on the forums.

I love your products I use the 20w50 in my Harley for the transmission and primary pulse the engine it works great where ever it is placed. The bike seems to run a little cooler than with other oil

Nothing but the best for my baby's!

Great price, very convenient having it delivered right to my door for free!

Use this in a couple Harley's when doing the oil changes. First off there was a noticeable change in engine tone. Engine runs smooth. Also put it in the primary and no problems. An interesting thing found is how clear the oils is still after 3k on one and 5k on the other. The "manufacturer" brand oils seems to get darker well before that. I also want to point out that even after long long rides to and from the oil level hasn't even dropped! No one drop still at full. Been riding around with a extra qt for nothing. Will continue to use from now on. So far very please with this oil. Would recommend.

I use this product in 2003 Dyna Lowrider exclusively. Since the switch from the factory synthetic, I have noted less upper valve train noise and smoother and quieter shifts. This oil does everything I need it to do for my bike, and I have switched all of my engines and machinery around the house to Amsoil products as well.

The best oil I have ever used in my numerous Harley Davidsons I have taken a number of long haul trips from desert heat to the Rockies doesn't break down like conventional oils do I only use Amzoil in all my vehicles

Best oil in the world. The only thing I trust in my motors

I use this product in my 2004 Heritage Classic with 67000 miles. The temperature always stays at about 200 degrees, well below the operating temp of 230 degrees.

Are use this in my motorcycle, it runs cooler and quieter. the bike has 95,000 miles on it and it's running just as good as the day I got it.

2016 HD Road King

Literally the best oil I've tried and I've stress tested this on numerous occasions. Over 2000 miles in 115+ degree heat riding for over 20 hours in a day. Best in the biz for sure

Wouldn't use anything else in my motorcycle
