Not sure why BMW would "push dealers to sell injection flushes" when they don't get anything for them. Premium fuel is already required and nearly always contains cleaners. It's the DEALER who want's to push any service to make more money.

Where's your proof Costco gas is bad, and will lead to dirty injectors??
