Engine oil AMSOIL or Mannol

Have used it for a couple of years now (since 2021) - I believe in changing my oil often instead of buying a more expensive one. It has been working really well (BMW B58) with no issues at all.

Amsoil 5w-40 in my 3.6 Corrado that gets pushed hard to redline often and has seen somewhat high oil temps when driving harder. I use liqui moly 5w-40 in my 3.6 CC and 3.0T Q7.

if you to go for the best oil and the most expensive ones, you can use liqui moli, valvoline, ams oil

I'm over 50 K on my current Amsoil change. I drive my car a couple thousand miles a month for work. I also put Archoil additive in it when I did the change.

I use it in my wife’s Fiat 500 and my mk7 Golf GTD(service every 5k miles). no issues at all.

Last service, I put 8.5L of Mannol 7908 in my e320 cdi. No issues so far

AMSOIL Signature Series 5w-30 with a black JDM Subaru Filter is the superior combo.

As long as the oil meets the BMW longlife-04 specification it will be fine.

I use Mannol 5w30 premium which has BMW LL-04 on the back of the bottle.

Got a call this morning from him and he said that the gasket/seal for the oil filter housing where it connects to block is leaking oil.

personally, I think Amsoil AFL is junk. They ruined a stout oil when they reformulated it to mimick 505.01.
