my 2 cents
Actually using ethanol in the fuel is far worse for your system. The reason bmw started using the cleaner was to combat the ethanol in the fuel. Pure gasoline has superior cleaning power over ethanol, methanol alcohol etc. Problem with ethanol is when it evaporates it leaves a horrible sticky film on everything, it also dries out gaskets, seals etc. We have had to change all the orings in our fuel systems at work because the ethanol will make them swell up and dry out and start leaking.
Even the ethanol free gasoline has the detergent package as the others have. Just like oil.
