2009 Challenger R/T 6speed manual
Forged motor built by Arrington Engines, 9:1 compression, cam, valve job, etc stroked to a 6.0L from a 5.7.
Magnuson Supercharger at 12lbs of boost
Shop that built the motor says to run 15W50 however, they're a race shop so I'm not sure they think outside of track use and I just street drive this beast. 15W50 seems too heavy for a street car especially in winter.
I notice Ford calls for 5W50 in the GT500.
What do you guys think? I run Penzoil Platinum 5W30 in my other cars. It looks like there's PP 5W50 but I've never seen it.
What say you? Got recommendations on viscosity?
