I change all three , oil, transmission and the primary. I believe this helped in my fuel economy , I got 8 to 10 more MPH with lest friction.
Will not go back to other brands!
Bottom Line
Yes, I would recommend this to a friend.

I have never purchased Amsoil in the past. This is guaranteed the best oil I have ever used. I did all 3 holes in a 2013 Harley Davidson Ultra Limited with 15,000 miles. The engine sounds great definitely an awesome product.
Bottom Line
Yes, I would recommend this to a friend.

Product was delivered quicker than expected and the quality of the product is what you would expect from such a reputable company. This product even made my road king run smoother and quieted the typical lifter noise that comes from the old girl. Well worth the money!
Superior to all other V-twin oils. Used to run Mobile 1 V-twin, which is better than Harley oil, but nothing compares to Amsoil! Helps reduce engine temperature in the heat of summer, and everyone knows or SHOULD know, excessive engine heat is a very bad thing! Modern Harleys are tuned to run lean and hot from the factory to pass EPA emissions....Amsoil will protect your engine better, longer. Harleys are expensive, don't run "average" oil...Run Amsoil, you will be glad you did!
Well, to be honest, I haven’t had the opportunity yet to ride my bike, to see what changes I could tell at first, however, due to Projects, rain and believe it or not, I went up to Harley-Davidson to get a new derby cover gasket and when leaving, it wouldn’t start, so had to leave it. Just got it back a couple of days ago, then rain, also my sod project needed attention, so hopefully in the next couple of days, I’ll get it out. So, the website was great, the ordering process was easy and the delivery was outstanding. Anyways, from what I heard, it was time to try it, I’ll have to get back with you guys or ladies on the performance of the bike.
Get kit fast delivery always used amsoil in my snowmobile and other bikes , never had any issues, so into my trike it goes, very convenient web site click on your bike ans away you go, also finding my bike is running a bit cooler with this oil. Thank you
Excellent kit, it has everything you need for the oil change in one box. I ordered several boxes for gifts over the Christmas Holiday. They were well received by my fellow riders.
