Will Stabil harm my fuel injection or turbo system?

I personally run a can of sea foam thru my vehicles about once a month. I try to always buy my gas from the same station or if out of town the same brand gas from a station near an interstate where I know they have a big turn over in the amount of fuel they sell. Chevron with techron seems to be the brand that runs best in all my vehicles old and new.

So you think that the additives placed in gasoline is harming your BMW? Try to find gas without ethanol- it seems counter productive to put additives in your tank when you are afraid of additives- I wouldn't do it-

Make sure if you use a additive it has PEA in it. Mobil is best for 87 octane car and Shell if you use premium. Chevron is very good if you can find it.
