Then how do you explain they are printing BP on the manual. Is your car really going to suffer if you don't use Castro for motor oil? BMW recommends Castro oil. I know for fact that I have done Costco gas for more than 3 years with BMW, M-B, Toyota, Honda; 4 spots, 6 spots and 8 spots engines. I think I have enough sample size to say at least BP or Costco is not the problem. My BMW GT is the only one having problem. The problem only comes when the colder temperature is present or if I don't touch it for a week.

I have people in BMW corporate telling me in private that don't waste the money on those injectors cleaner.
