Jason here. I joined your group due to all the great information I found as a lurker, so thanks! I have 2011 Grand Cherokee Overland 5.7 with 147,000 miles on it (not a misprint). This was my company vehicle that I've had since new and was given to me as part of my severance package. No problems to speak of other than a bad AC compressor, and have always had all maintenance done at my local Valvoline center. Now I'm digging into it a little bit and adding some underhood goodies (i.e. K&N 77 Intake, Jet Stage 1 Module, and Jet Throttle Body Spacer). Woke it up a bit!
In case you wondered, I'm a Harley Davidson guy too and have a few, but primarily ride a 2012 ElectraGlide Ultra Limited in black.....Electrablack. Hence the handle, because how do you really pick a name? That's a commitment! Haha...
