All the reports are true ... V-Twin 20/50 works great. My spent oil at recommended intervals looks like it could go another 3,000 miles.
November 13 2021 I had my, 2007Harley Davidson Ultra Classic, Dyno Tuned, the technician was surprised how cool my bike ran on the dyno, most bikes he needs to shut down after running WOT for a wile but mine with Amsoil 20/50 V-Twin oil ran a good 20 degrees cooler than expected. I have been using Amsoil in my Harleys since 2002. I started using it in my 2002 XL1200 S 12 second quarter bike, and never looked back. Thank You Amsoil.

I've had my 1998 Harley-Davidson road king classic for 10 years.I started using all Amsoil products each season when I put the bike away for the winter about 3 years ago. I'm very happy with the products. I use 20w50 synthetic oil for the crankcase. Amsoil transmission and primary fluid too.
I use Amsoil in my Indian Motorcycle. The large air cooled engine puts off a lot of heat, especially during summer in south Mississippi. The engine heat was greatly reduced after switching to amsoil, so you know the engine is having less wear.
I didn't ever think I'd be able to afford Amsoil, however, with the price of oil going up all over the place, is not that much different. So now I can finally afford Amsoil, yeah me.
