Engine oil Shell or OEM Subaru

I'm using Shell Advancen AX7 10w-40 na 800ml sa ADV 160 ko. Swak na swak yun!

I use 5w30, I used to use Schaeffer but it's too expensive now so I switched to Rotella.

Oil consumption was the biggest issue when running 5w30. Changed to a 5w40, 10w30, and then got recommend 15w40 and oil consumption stopped

Rotella T6 ! Zero issues.

So far itong si Shell yung may pinaka smooth na oil sakin.

It completely transforms the bike , it resists heating like it almost non existent even after a hard session of riding, performance is consistent in warm up, cold start or all kinds of situation ,fuel efficiency definitely increased, and the acceleration is also noticable better and power is also good compared to when I used to run on liquid gun and on highways the bike totally becomes a beast . I highly recommend shell to my fellow riders, it's the one that completely suits RE engines

I switched to 5w30 shell from 10w30 havoline.

No problems. The engine is a little bit cleaner.

I am using Shell Helix Ultra 5w40, fully synthetic for my Lancer (2006), change it at around 7000 KMs. No complaints, my travel includes short & long distance, very happy & satisfied.

I run Shell Rotella T6 5/40 I live in Florida. Slightly high copper on the STI. The Tribeca is fine and purrs like a kitten.

I did use the Shell T6 Rotella 5W40 for 4 OCI's and then got a misfire issue. When my mechanic was going thru the possible symptoms he asked what oil i used. When i told him it's a full synthetic deisel truck oil he shook his head and said that not a good idea. Too thick, and that could have an impact.
