I sometimes use junk gas, but I also use a PEA fuel additive 1000 miles before an oil change.

We haven't put any Sams or Costco gas in the X5. It's been fed a stead diet of Shell or Exxon premium fuel.

I'm a bit worried about this E15 mandate nonsense given that BMW has stated that it's not approved for use this engine. What's the world comin' to?
