Engine oil Shell or Eneos

For the FA20, I like Rotella T6 Multi Vehicle 5w-30.

Engine runs super smooth with that oil.

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

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

If you look at the forums there’s tons of information on this. The rotella T6 5w40 is considered to be the best oil for the EJ hands down.

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 15W-40 Shell [B]Rotella in my Volvo because it's an old turbo car and the enthusiast community has had success with it.

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