2015 Mazda2 Sedan fuel type question

2015 Mazda 2 Sedan
Hi All,

Last week I brought a used 2015 Mazda 2. By looking at the user manual, it suggests I can use 92 octane petrol to fuel the car. But since this has a SkyActiv engine, don't I have to use premium fuel (95 octane or above) because skyactiv has a higher compression?

Is there anyway I can find if my SkyActiv engine has this high compression mazda claims or is there a version of the skyactiv engine that has normal compression like in old mazdas?

It is a 1500cc engine.
