I’m using Amsoil Signature oil.
Yesterday I took my car in for an oil change and got amsoil. I read countless comments of people hating on the price, this and that, but let me tell you somthing, that amsoil ain't a gimmick or a rip off. My car drove sooooo much better afterwards, it kinda shocked me. Smoother, seems faster, more. Consistent shifts, just left me feeling like she felt the best version of herself.
Go with ams oil I use to talk mad shit about the product but honestly I’m pretty satisfied with it because Harley’s syn 3 is just become trash leaving lifters ticking on and the bike has always had the Harley tick but it has quieted it all down. Just my opinion though..
I use Amsoil in all three, but I use their VTwin kit for my M8. Different trans, primary and engine oils.
I was absolutely amazed at how much smoother and more responsive the bike was.
Ams oil, yes it's overpriced but it is the best and going from stock HD fluids in the primary and tranny it does shift noticeably quieter and it's much easier to find neutral
I use Amsoil for all 3 and ride a 2008 H-D Softail Crossbones
I use [this for crankcase oil](https://www.amsoil.com/p/amsoil-20w-50-synthetic-v-twin-oil-change-kit--4-quarts-with-chrome-filter-hdck/) - now 4quarts = 1 gallon so there's a bit extra in this but it also comes with an oil filter.
I run amsoil. They have specific oil for all 3 holes. Seems to quiet down transmission and primary on my 01 road king
I run Amsoil signature with an amsoil or wix filter, I usually only do 3k intervals to keep the 257 happy though lol.
One step above “full synthetic” is “100% synthetic” from Amsoil. Switched years ago, car has a subtle purr.
After not being very impressed with Amsoil 5W-30 after a 5,000 mile oil analysis, I'm going to see how this stuff looks after 5K.
