Unleaded 95 RON(premium unleaded)
RON stands for "research octane number". For those of us in the United States, if you look at the local gas pumps, they have a little yellow, federally mandated sticker that has the octane number of that fuel and under it in fine print it reads "R+M/2 method". That means it is the research octane number and the motor octane number added together and divided by two. In other words, the average of the two numbers. The motor octane rating is figured differently and is most always at least a few points higher than the research octane number. Sooooo, the 93 octane at the local pump does, in fact, meet the 95RON requirement that Mazda calls for.
