Hi Experts,

• any advice on what type of gas to put in my Mazda CX-30 Premium Trim (87,91,93)
• don’t want to unnecessarily waste money by putting Premium gas (if it makes no difference in the long run)
• also amongst the gas companies, any recommendations which one are the better one’s (I see the regular gas in some pumps say contains 10% ethanol, while others don’t say this)
• Options available near our home: Costco, Sunoco, gulf, bp, shell, speedway

what does it tell you in your owners manual?

Couldn’t find any mention of which type of gas to use, hence thought of asking the experts here

Mazda lists Regular Unleaded on their website for all CX-30 trims.
So you should be good with Regular 87 octane (US).

don't have a copy of the US owners manual but have the Canadian one so I presume it should be very similar, and found this on page 3-28 under "Fuel and Emission" (looked up "Fuel" in the index)

87 regular unless you are in a really hot environment where engine detonation is prone to happen, then higher grade.
