I just bought a 2008 Mazda 6 through a car dealer online. the first time I went to fuel up I noticed the sticker next to the fuel cap says to use 95. is this necessary. will it effect my car or its performance to use 91?

Hi there, it is always best to use the fuel that the vehicle manufacturer recommends, this is to ensure engine longevity and optimum performance.
