Engine oil VALVOLINE or OEM Mazda

I’ve used a few but the best for me is mopar oil filter and Valvoline full synthetic.

I’ve been using Valvoline full synthetic with a KN filter. Never had an issue

Valvoline full synthetic with max life tech is my current favorite but I think I might be able to unseat him soon.

After reading several posts I got the Mazda Molly and Personally really like it! With the Molly it seems to run much quieter not such a heavy tick and just overall feels better’

I personally use 5w50 valvoline fully synthetic racing oil for my r56 and change every 5000 km which is like around 3k miles and it's running good

For the money the best zinc content is valvoline vr1 CONVENTIONAL (not synthetic). It comes in a few flavors.

I run 5w-40 in everything. Mazda Skyactiv, Toyota 3UR, Honda J35. They all like it and run quiet.

I use Valvoline 0W-20 full synthetic and an OEM filter.

I used to run the 10w-40 Valvoline high mileage synthetic blend from Walmart.

I bought a Mazda CX-5 dealer test car with 300 Km's on it back in 2015 when I moved up to Osaka. I drive a LOT and was getting the oil changed roughly every 5000 km's per Mazda's recommendation.
