Idemitsu zepro eco medalist advanced moly 0w-20. Basically the same thing as Mazda's oil.
Best Engine oil for Mazda 3
Pros: high moly oils
Vehicle:
Mazda 3
Use a good quality synthetic engine oil; I use Eneos.
Pros: good quality synthetic
Vehicle:

They should be using 0W20 full synthetic oil (not synblend crap). Its not going to hurt running the 5W20 in it instead but next time mention it at write up. Mazda claims benefits such as better cold start protection and better efficiency among other things.
Pros: better cold start protection, better efficiency
Vehicle:
Mazda 3
My car runs full synthetic, no additives. I find a 2.0 engine oil filter mount swap(from cartridge to screw on), royal purple filter, and penzoil ultra/platinum are an amazing combination.
Pros: amazing combination
