Engine oil Eneos or IDEMITSU

The oil was Idemitsu Synthetic 0W-20 with 12.5k miles on it. Once again, trace metals and flashpoint were within normal range. I also ordered a TBN to measure the amount of additive left and that showed there was still plenty of active additive remaining.

Eneos 5w-30 full synth for my 06 WRX. It has a high zinc content.

In terms of oiling, get a sohn adapter so your apex seals aren't being lubricated with crankcase oil, and instead are injected with rotary-specific oil, like idemitsu.

I have exclusively used Eneos 0w-20 in this car - the non-Sustina version. This past oil change, I started using Eneos Racing Street 0w-20 as they're phasing out the OG 0w-20.

Both have worked very similarly for me. No issues with anything other than E85 dilution when I'm running it.

I run Eneos 0w-20. Lots of people love Mobil1, if only because it is often on sale at WallyWorld.

Eneos 5w-20 in my 2008 2.3 liter Mazda3. It's a Japanese-branded synthetic oil that you can get from Napa Auto. I've found that with Eneos, my Mz3 stops consuming any oil (in both my 2007 and 2008 2.3's).

Subaru OEM oil is Idemitsu 0W-20. I currently use Idemitsu Zepro\* 0W-20, a high-moly formulation from the same manufacturer.

Eneos 0-20.

That's the wrong oil. You want the Idemitsu eco gold medalist advanced moly 0w-20, which is basically the same as Mazda oil(Idemitsu makes the mazda oil).

Idemitsu zepro eco medalist advanced moly 0w-20. Basically the same thing as Mazda's oil.
