Quickservice noticed a difference since I switched to amsoil

Amaoil is the original synthetic and the leader in quality. I use nothing but Amsoil in all my vehicles from my truck to my ATV.

Perfect for Harley

Been using this product for years great oil, they offer the correct oil for the three different holes on my bike, not the one oil fits all crap!

My FLHTCU now has 72000 miles on it. From the first 600-mile oil change, this is the only oil I have used. My oil is changed every 5000 miles. Every time I change the oil, I submit a sample for analysis. Each time, it comes back clean. At my last full service, I did a cylinder leak-down test, and the results returned 5%. Outstanding for an air-cooled engine at 70000 miles! Best oil on the market.

I have been using Amsoil in my Motorcycles for over 20 years. I service many bikes in my shop over the course of a year & always suggest Amsoil. Have never experienced any issues. It provides the needed protection for all temperature ranges. I just returned from a 6200 mile motorcycle trip with absolutely no issues. I also like the extended mileage between oil changes. I typically go 7500 miles between changes but accidently went 10,000 miles one time and the oil looked normal when I did change it.

I only use Amsoil products in my Harleys, nothing else.

Definitely an excellent choice for maintaining engine performance and endurance.

Excellent pour mon Harley

I’ve been a mechanic all my life and always use Amsoil , have had it tested after use and could keep it running longer . It out last Harley oil by far and is a better lubricant, I also use it in my Diesel and always will . Oil is the heart of keeping it lubed so use the best.

Can buy this great oil many places but I always prefer to deal with these great people. On time delivery and good prices. Thanks

Will always use your product

This is all I use in my 2012 ultra glide

This oil is excellent. Have never had a oil related problem with Amsoil . I ride a lot and with sitting in traffic or having to go 5 miles per hour in bumper to bumper traffic with a air cooled motor i have never had the engine knock from over heating.

20W50 Amsoil is pretty much what everyone recommends for their Harley Davidson. Amsoil customer support is the best I’ve dealt with from any merchant.

I've been using this oil for years on several bikes and have always been pleased on its performance

Perfect for Harley

Ordered one day. Had the product the next. Cant get any better than that. Awesome company and product.

I only want the best oil in my Harley. All the research has brought me to Amsoil

I have a small based Harley shop and use only Amsoil… Technical support is great and shipping is fast
