Best Engine oil for Mazda 3
Mazda says every 7500 miles for normal duty OCI, and I’ve done every 7500 miles since brand new on my 2014 3z.
It’s now at 187k flawless miles, consumes no oil *at all* (I’ve literally never had to add oil beaten changes, ever, what goes in comes out every time), runs like new, seems easily headed to 250k.
Pros: consumes no oil
Vehicle:
Mazda 3
Mileage: 300967 km
Grab a good quality 0/w20 synthetic. I'm currently using Pennzoil and a Fram filter.
Pros: good quality synthetic
Vehicle:
Mazda 3
Mileage: 120000 km
Castrol edge and OEM filter for turbo.
Cons: blend formula

Regarding brands, if you want to stick with factory oil without dealer price, Idemitsu is the brand to get. I emailed Mazda corporate and they said Idemitsu is the OEM for their oil.
Pros: OEM for Mazda oil

For Naturally-Aspirated Skyactiv engines, it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. Arguably it is one of the best oil for skyactiv engines.
Pros: highly recommended, best oil, high molly

On my ( 2006 Mazda 3s 2.3l auto sedan 350k miles ) I don't burn a single drop of oil and the car runs great even the transmission and I've been sticking to 5W20 Castrol edge extended performance all year
Pros: car runs great
Vehicle:
Mazda 3
Mileage: 350000 km
2014 3, 0W-20 full synthetic (whatever major brand is cheapest) from brand new, every 7500 miles.
170k, runs like a top, burns not a single drop between changes, compression and fuel mileage exactly the same as new.
Pros: runs like a top
Cons: whatever major brand
Vehicle:
Mazda 3
Mileage: 170000 km
I use for 2 years Castrol 5w30 its perfect after for top up i use Ina (croatian motor oil) and works perfect
Pros: perfect for top up

From my knowledge it doesn't matter what brand you put in. Just make sure its quality oil that's rated for your car and do oil changes regularly. I have used Mazda branded Moly 0W-20, Mobil1 Extended Performance 0W-20 and currently Pennzoil Platinum 0W-20. Honestly I can't tell the difference between them at all.
Pros: quality oil, regular changes
Cons: no difference between brands
