Who's instructions? The only mention of detergent in the 2012 user manual is this:
"Should you encounter driveability problems which you suspect could be related to the fuel you are using, we recommend that you respond by switching to a recognized high-quality brand such as gasoline that is advertised as Top Tier Detergent Gasoline."
BMW have a long term deal with BP for lubricants and the manual even says they recommend BP fuels by name (cross promotional thing, but nonetheless).
Techron is a Chevron product.
