Engine oil Eneos or PETRONAS

There is no “break-in oil” just ENEOS brand 0W-20. KIA and ENEOS have a partnership and the factory oil fill is this oil

I'd stick with oem or put some better stuff like Motul or Eneos into it. Eneos has some relation to Honda oem oil I forget the story. I use to put only mutul into my car but have recently switched to Eneos, will be putting eneos 0w-20 race prior to tune.

For shits and giggles I switched to ENEOS 5w30 synthetic in my 2 current vehicles and now I'm able to go 5,000 miles between oil changes and while some oil is still consumed, it stays above the "add" line on the dipstick without adding oil between oil changes.

Petronas Syntium 5w 30 on a mercedes and audi a6. No complaints at all, and good price

I use only Eneos 0w20.

I normally use Mobil 1, but did experiment with a JDM brand called ENEOS. The engine seemed to run smoother with that engine than other brands I've tried before.

Eneos oil. Japanese full synthetic. Use it on my 96 accord. Good stuff.

The 5W30 full synthetic engine oil works the best for a wide spectrum. Its working temperature range is practical for daily use and it costs less than 5W40.

My giulietta 1.4 MA is still reliable at 130k km. Never had any problems with engine always used recommended petronas oil. Had to rebuild my turbo once (at 120k km) it had very little play that made my car burn some oil.
