Owner reviews for engine oil

Motul X-clean efe for my 2016 WRX! 5w30. Hands down the best oil for the turbo FA20 engine.

I use rotella 5-40 in mine. It's really cheap for a full synthetic and I saw less oil consumption after switching. It's intended for diesel engines but I haven't seen any negative effects after using it for 60k miles. I usually change it around 4k miles.

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

I use Rotella 10-40w Diesel oil. works great.

I use Amsoil 0w40 or Eneos 0w50 in mine. For sealing and shear resistance for metal to metal contact, thicker is better.

I used Shell Rotella T6 5w-40 for a while (not cat AND Sohn installed) and it was fine.

I have a couple of oil changes of the M1 0W30 ESP. It does meet the spec.

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 run Brotella T6 5-40. 22.50 a gallon from amazon. Fantastic Stuff.

That is what I have used for the past 3 years in my 97 m3. I havent found any difference between the LL-01 and LL-98 versions.
