No, 5w30 will not hurt your 8.
The only difference between 0w20, 0w30, 5w20, 5w30, 10w40, 20w50, etc... is how thick the oil is when cold and when hot. 5w30 is recommended for the rest of the world outside of the US, 5w20 within the US, and Mazda has never made a single weight of oil a requirement.
How thick of an oil to use is the subject of massive debate on here that probably will never be solved.
Your fine.
