Engine oil AMSOIL or Mannol

Any synthetic - I like the Amsoil.

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.

Also been using Mannol. Do 6k oil changes though. Made chain noise on start up. Swapped back to mannol noise gone.

I've used Mannol for a few years, it's dirt cheap here in the UK and I've never had any issues with it.

Using Mannol since years in Mercedes Diesel and gas engines , also in a BMW Boxer.

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.

I used Amsoil 5w40 European Car formula or Gulf 5w40 Formula G in my A6 previously. Technically Amsoil doesn't have the have the VW 502 00, 505 00 certifications so I think I will start using Gulf Formula G or GX exclusively in my R, either the 5w40 or 5w30 grade.

Those guys don't replace you crush washer, and the oil the use is crap.
