Engine oil Eneos or IDEMITSU

i am of the mindset of using oil from the region. my GTI is a german car and gets liquimoly, a german oil. my toyota/subaru is Japanese, Idemitsu is a japanese oil (and the oem supplier for Subaru). i have 5w30 in it now.

I change my oil and the filter every 5000km,and my engine is running smooth after 280.000 Kms,with no oil consumption. Use ONLY full synthetic oil. Personally i use Eneos oil.

Been using Eneos & changing it every 4k miles/4 months. Congrats on the WRX

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've been running Idemitsu oil in the XT and the wife's Crosstrek for the last four and five years and have been happy with it.

You’ll be fine, idemitsu is a bit of a rotary specialist when it comes to fluids

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.

I think Idemitsu is the better option if you have access to it. Mostly because it was developed for the rotary engine.

Idemitsu to both, because it’s designed and tested on rotaries.
