Hey everyone, first time poster so please bear with me. I just got a 2015 Mazda 3 SP25 and am wondering which fuel type is best to use. The importer I got it from said it should use 95 though I am wondering if 91 will be okay? Obviously the price is a little steeper so if it doesn't need the 95...

Anyone know how to change the small blue light overhead, actually on when turn on parking light or headlight , my light is wont turn on , thanks
