Winter Blend Gasoline
Hello,
I have noticed that when i fill up my 2012 BMW 550iGT in the winter the car tends to sputter and hiccup when accelerating. This does not happen in the summer. Does anyone have a reason why this might be the case? I believe this is because of the winter blend of gasoline that is using ethanol, or some other derivatives but I don't know for sure. Just curious if others have experience this same type of situation.
Thank you
George
