As above, only recent engines are DI, millions still running from before dont have the DI problems

Techron also seems quite good at cleaning the combustion chamber, atleast on engines tear downs from a local tuner ive seen

Believe that is the local USA parts code.
Many products that arnt available in all countries have a local country codes.

Here for example our Engine oil, Brake fluid and Coolant that are locally produced for the 3 Series factory and dealers do not have parts codes that show up on the ETK and we cannot order the ones that appear on the ETK.

Techron is not available in all countries and may not be compatible with all countries fuel, so it has local part numbers not on the ETK in countries that stock it.

Its anyway MUCH cheaper if you can get it from Chevron or Caltex or another distributor rather than BMW dealers.
