Hey buddy.... Thanks for the question... To be honest, I have never heard of the product
In your thread..... All I can tell you is that I stand firm on using bmw products on and in you car. My car was not starting.... Because of using 93 octane QT GAS... I got a bottle of BMW fuel system cleaner with "Techron" an 93 Chevron gas, and my car turned into a jet.. And I have not had a problem since.... Your car is a 12, so if it helps an 03, then I'm sure it will keep your car tip top!!!!
