Engine oil OEM Mazda or ZIC

Before 2023 i was using zic 0w20 but caltex has newer technology

Used this for my old Alterra that made it to 250k mileage. Good budget option.

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](http://www.cleanmpg.com/community/index.php?threads/45295/#post-357910).

One of the best engine oils, exclusive Zic lang ginagamit ko, and it's a Korean company so alam mong goods yan. Pero ako Zic X9 ang ginagamit ko, mas mahal kaysa sa M9 pero API SP naman na and may resource conserving certifications kaya mas madulas and mas tipid sa gas.

Been using it for over a year now sa daily scooter ko. Change oil every 2.5k kms, and so far, less wear and tear naman. Engine feels smoother, and surprisingly, di ganun kadumi yung langis pag draining time. Solid for daily use.

Im using zic sa vehicles namin. So far ok naman.

SK Zic 5W30 Diesel

Zic X7 5W30 Gas / Diesel

Many reputable rotary shops have tested numerous oils over the years, and agreed that the bearings do not have adequate protection with 5w-20 or 5w-30, especially if you track the car or do any spirited driving regularly.

they only say you can do that with their Mazda-branded oil. That stuff tends to be expensive.
