Engine oil Kendall or OEM Mazda

Could be weather related. I'm in Canada and we have weather from -35C to +35C, so Mazda recommends oil changes every 8000km instead of 12,000km.

I use original Mazda oil and Nipparts for the filters. I live in Europe and I buy these for 80€ / 85$.

For [Naturally-Aspirated Skyactiv engines](https://en.wikipedia.org/wiki/SkyActiv), 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]

I bought a new air filter for carb. I reinstalled the front engine pan. I did an oil change. VW specialist recommended I go to Kendall 20w50 to fix the oil light at idle.

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 use full synthetic kendall and it runs beautifully.

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

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.

I use Mazda's weight recommendation for my environment, as illustrated in your owners manual. I use 10W-30 and 15W-40 Full-Synthetic oils with zinc additives to stave off carbon deposits.

Ran Kendall 15x40 for a number of years, ran Shell T4 till it got oddly hard to find, currently running Delo 15w40
