So what I am wondering is that I am running royals purple 5w30 synthetic oil in my k24/k20 NA motor with the royals purple synchromesh . So if I am installing a supercharger on thaw motor do I run a thicker oil or just keep using the 5w30 like usual ?

Is it better to us a thicker oil or just keep using what I us now.

I am a newbie towards force induction and learning on the way.

Thanks.
