Are you guys still using 5W30

[Four Door GSR]

With your JRSC setup?

Wouldn't a thicker oil protect better on forced induction?

Nope i use Royal Purple race 41 which is about 10-40w in summer and 5-30w in winter.

I run pure Penzoil synthetic 5W-30W with Pennzane (developed for the space program and used by Nasa). If your in a hotter area of the country, or summer, you could go 10W-30W or 10W-40W. I would definately go synthetic, especially with a super or turbo charger. Your oil is your engines lifeline!

I run Redline 5W-30 all year... and MTL in the transmission. Lucky for me it never really gets very cold here.
