I figured I'd throw some good info out there for anyone looking to DIY their oil change. Let me preface this by saying I am not an engineer or a certified Jeep mechanic so take what I'm about to tell you outside of the normal oil servicing as one enthusiast making some inferred guesses based on 16 years of garage wrench turning and 10 years of fighter aircraft maintenance. If an actual engineer or certified tech from Jeep can confirm or deny any of this, I'm all ears.
Everything about the oil change itself is standard 2.0L Turbo stuff (torque specs, quantity, oil type, filter size, etc).
Where it gets interesting however is your first start after everything is put back together. When you start the jeep after swapping fluids, the engine will immediately turn on without having to press anything outside of the brake pedal and starter button (e-save, shift to manual, whatever, they aren't needed).
Apparently Jeep was smart enough to program the system to recognize when it's had an oil service done (again, my guess but if it's correct, well done engineers).
The hood posts that recognize when your hood is open/disables external charging to the J1772 port can be finicky to deal with if you did your run up with the hood open (as most mechanics do to ensure everything is operating correctly with no leakage). If you shut down the jeep with the hood still open, the system will remember this and will not allow you to plug back in again even after you've closed the hood with the engine off. You'll have to turn the jeep back on (foot on brake, start) for the system to reset itself before shutting down and allow for external charging to resume. What you'll notice on this second start however is that the ICE will NOT fire over this time. MY assumption here is that the system now recognizes the oil servicing was completed and resumes normal operation in hybrid mode.
This was a very straight forward process overall. The whole hood post issue I ran into was an interesting twist but didn't take long to troubleshoot at all (maybe 5 minutes). If anyone feels intimidated by the whole hybrid aspect of this vehicle to swap the oil out, don't stress. It's very easy to do. After reading all the insanity in the news about the dealership suing the owner during a routine oil change on a manual wrangler, I'm finding more and more reasons to avoid the service bay at the dealership. I'm at roughly 3000 miles on the ICE alone (if not slightly less) and my oil life indicator was showing 25%. I can confirm the oil coming out looked like black death and the filter wasn't any better. I highly encourage staying on top of your oil changes with this vehicle considering how much start and stop the motor does in hybrid mode. You'll be shocked at what comes out.
Hope this helps everyone!
