But my dealer says nay, nay! No 0W-30, no warranty! - just to be clear, I guess due to the OPF we are bound to the LL-04 specification.

Thus I am being forced to use this:

Still a great oil... but somehow it bothers me.
Just curious, how would the dealer know what oil you used?

They do the work when they service the car... thus the see what oil I bought and asked them to use.

I'd only run 5W50 redline. The only reason BMW uses this 0w30 is to meet epa guidelines and for fuel economy. Other than that that oil is shit. I'm willing to bet any engine running 0w30 past 15K will show bearing wear (silver or copper shiny looking shavings) after oil changes especially in your filter. And don't tell me that your bmw tech told you oil looks great bc that's a lie. Most of them don't know shit about that part and just follow bmw guidelines. Do your research on Redline 5W50 and you'll see it for yourself.

Do you know anything specific on why Redline 5W50 is better than Amsoil Signature Series 5W50? Other than Troys experince with S65/S85s?

I wouldn't run Xw-50 unless I was tracking the car. No way the oil is getting hot on daily driving to need something that viscous.

0w-40 is as high as I would go for daily.
