Alfa Mito 155TB
Hi Just been out to put half a tank of optimax in the 172....before starting the car up again, i turned the ignition onto position 1 so the fuel pump could be heard wurring away...switched it off and then back to the 1 position for the fuel pump second time...then started. her up.....maybe the performance felt better...maybe it was because i had added more optimax...maybe it was in my mind....has anyone else tried this?
