Engine oil Shell or RED LINE

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

I stand by Redline 5w20. Not that I have bad “hemi tick” on my 5.7 but I swear the valvetrain is the quietest when I use that oil.

I personally use Red-Line products, and it's the absolute BEST products out there. Their 2 Stroke racing no smoke oil is OUTSTANDING and 2nd to none.

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.

Redline and royal purple filter for my 17 ram sport 5.7. 60kish on it now.

Why spend more when you can buy Shell Helix Ultra FS 5w40 from Lotus's, Giant or Aeon Big for half the price or less compared bought in petrol stations.

Nothing wrong with LiquiMoly, but I personally find Shell Rotella T6 to be better. It is quite a bit cheaper as well.

So when i changed the car to 10w40 redline I noticed that the car began to knock around 3-4k which it didn't do before and now it seems to slowly get worse.
