they sell these at most gas stations and at autozone.
i have been putting it in my 335 since 5k miles, every 5k miles, and have had no motor issues - car pulls as it did on day 1 - im at 20k miles.
i have been putting this in my e46 m3 for the past 10k miles and the car is tracked often (20 times a year), and i have had no problems.
i wouldn't request the dealer to put it in, unless you want to pay rape prices.
just buy one, drive your car till its practically empty (let it ready in the 20s in miles remaining) , pour it into the gas tank, refill, and repeat in 5-7k miles.
I would use the Chevron Techron - $7+ shipping on amazon

maintenance is very important in BMWs. It will cost a few pennies now, in order to avoid a few thousands later on
