1st in performance and 1st in products.

I have used this oil in all my Harley since it was new. Never had any issues with over 100,000 kms traveled. I just got a new Harley and will always use it in the new bike.

This is my second season running this oil in my 2008 Yamaha V Star 650. There is a noticeable difference in shifting. The bike shifts much smoother now. The bike runs cooler as well on really hot days. I will continue to use this oil each season from here on.

I am not reviewing the oil, although my bike shifts better with this oil and I love the longer change interval. I’m praising the AMSOIL customer service. I tumped over a quart and lost half of it that I needed for a change. I placed another order the following day. I emailed AMSOIL that night, explaining my plight. Kelly from Cust. Svc. emailed back the next day, and that order arrived got here in a flash. Kelly even replied to my follow-up thank you email. Great, great customer service.

After changing over to this oil my engine has never been smoother. I’ll definitely stick Amsoil!

This is the best oil for Indians, period. My engine runs cooler and quieter with Amsoil.

I’ve been using AMSoil for about 40 years in all my vehicles and for good reason, its the best! I won’t stop using it unless they quite making it, and that’s not likely to happen!

only oil my bike has seen for 16 years

This is the best Harley oil money can buy. I’ve put this oil in multiple bikes and had the engine run noticeably quieter. Also because Harley’s are already some what sensitive to warming up before you ride, the straight weight doesn’t have much down side in 55 degree and above weather.

This is the only oil I use in my 02 Harley because I want protection for my Bike so it will Last my life time

Makes my HD run cooler and smooth. Noticeable temperature difference when ambient Temps are hot.

Amsoil for life. I will Never put anything else in my motors or customers ever. BIKE shop owner.

good product

If you are trying to cool down your twin cam, for the summer... I advise you to run a thicker weight of oil.... I've been doing this for years and my bike has rarely been over 250°f I maintain my motorcycle at operating temperature 230°f .. But we all know that with traffic and lights, the bikes can over heat... This 60w has been absolutely a game changer for me... I've tried just about every brand out there and amsoil hands down beats them all... 1 key thing is that you definitely do not want to over fill with a thicker weight, your oil pressure at first will jump up 20-30 psi more.. When cold

Very good high mileage oil

2006 Buell Ulysses, gotta put the best in it! Amazing what an awesome quality oil will do for your bike. Spend the extra money and treat your machine. It will take care of you! Order the same time every year and its always shipped fast, even in this liberal economy! Thanks Amsoil!!!

Great oil and other products

Quality product with fast service.

I switched to AMS oil 20w50 in my 2015 Harley Davidson FLHR because both types of OEM Oils, synthetic and petroleum based, wouldn’t hold up. After 3000-4000km of hiway use I’d be down 1/2-3/4 of a litre. Bike had 25000km on it at the time. Proper break in. Leak down test proved engine was fine ect. The OEM oil just evaporated. I’ve used AMS Oil products on/off since 1979 so I gave it a try in my HD with immediate satisfaction. I change oil between 8000-10000km depending on my season or trips and add nothing between changes. Maybe down 1-2 cups of oil. It stands up. I have 140,000km on now(spring of 2022). I’ve have some friends experience the same with their Harleys. AMS Oil 10w40 is going in my Suzuki VStrom prior to my 12000km round trip to northern Alaska and back. Good stuff.

Excited to put this oil to the test in my 04 Harley sportster 1200.
