Did you mean oil changes or gas fillups? I just cheked and my local Advance Auto Parts has those in stock, so I will probably go get one right now.

This could definitely be it. I really need to take the car into a BMW shop, no way around that. This is happening to me multiple times daily.

You pour it in near empty gas tank roughly a quarter tank and then fill up the gas all the way so it mixes the concentrate throughly. I fill one bottle every 3,000 miles or every other oil change
