I wish people would just say they like a certain brand instead of insulting something without any evidence.

An excellent quality oil will perform well at the end of the OCI, so if you're going for 10k mile oil changes, that's important. Overpaying for that oil compared to the BMW oil or Liqui Moly makes sense. If you're replacing the oil every 4-5k miles, any oil meeting the spec is going to be virtually the same. Anyone with actual evidence to the contrary is welcome to share it.

And here in the uk we are on 19k miles!!
