supramatt1 Posted September 29, 2013 Share Posted September 29, 2013 I used a can of b-12 chemtool by Barryman's when I filled up my car last and I didn't notice any changes but I stoped at the movie store and parked while idleing not giving it any gas my car reved up to 6k rpm for 3 seconds and than went back to idle does anyone know why that happened I am not worried about it but it was strange can anyone tell me why my car did that? is there any good octane boosters that are not orange and that are safe and help with sputtering of engine?
