To me it feels like the car is smoother and more responsive.
(maybe it's just that I'm operating in the higher rev range now I can, or maybe it could be due to the fact that I switched from Costco Premium to Shell V-Power a couple of days ago)
Interested to hear any thoughts...
Just curious, but why aren't you using the factory oil? Didn't BMW cover your 1200 mile service?
