Hey guy’s, about 300 miles ago I had the differential replaced under warranty on my 2019 scat pack challenger with 8000 miles because it had a severe whine coming from all speeds, the new one makes a little noise but is 100X quieter. I’m wondering if I should change the fluid at 500 miles or...
I just got a new 2016 Challenger RT Scat Pack.
I have heard it is not good to rev a new engine over a certain RPM or go over a certain speed until you hit X amount of miles. Can anyone give me some more information on this? Would really appreciate it.
