Engine oil Shell or AMSOIL

I have used Amsoil for years and I change my oil every 15,000 to 20,000 miles.

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

Amsoil 5w-40 in my 3.6 Corrado that gets pushed hard to redline often and has seen somewhat high oil temps when driving harder. I use liqui moly 5w-40 in my 3.6 CC and 3.0T Q7.

if you to go for the best oil and the most expensive ones, you can use liqui moli, valvoline, ams oil

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'm over 50 K on my current Amsoil change. I drive my car a couple thousand miles a month for work. I also put Archoil additive in it when I did the change.

AMSOIL Signature Series 5w-30 with a black JDM Subaru Filter is the superior combo.

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

I have used Amsoil, but I feel as if my motor makes a funny noise with that in it.
