Only Oil I would use

Over the years of owning my 2007 HD Ultra Classic, and after 70K miles, this is the only oil I have used.
My bike came from the factory with HD oil, but at the first oil change, (500 miles), and every oil change thereafter I have used Amsoil.
NEVER had an oiling problem. The current cylinder leak-down result is 6%. You can't complain about that after 70K miles.
Here in Oklahoma the summer heat can get pretty intense, like 105-109 degrees f. intense. My Thunderstroke 111 runs great with Amsoil in it and it quietens down the valve train too. I highly recommend Amzoil products for your motorcycle,I've been using Amsoil for over 25 years.
Bottom Line
Yes, I would recommend this to a friend.

I’be been using Amsoil exclusively for 5 years with no problems yet. Amsoil cuts down on the engine noise and makes it easier to start the bike on cold days, (Easier on the starter) .Remember the Amsoil filter.
Bottom Line
Yes, I would recommend this to a friend.

This is all I use on my motorcycle. I know that it's the best and will help the engine last.
I've been using this oil for about 20 years. I've had multiple experiences with the motorcycle and in my vehicles with heat issues. I have been at bike week numerous times when other v-twins were pulled off the side of the road overheating and I kept on rolling! I also had to drive a car home with no coolant in it with Amsoil and never even went above a quarter of the way on the temperature gauge. I'm telling everybody Amsoil is the way to go and I will never use any other oil in my bike or truck ever again!! It is the best!
