The main reason as stated above to change your own oil is shop incompetence. I have so many friends with stripped drain plugs, cracked oil coolers and the nut broke off of the oil filter cap.
I have $55 plastic rhino ramps(the heavy 7000lb suv version) that I pull the front of the car on and a enclosed oil pan the oil drains into. The Castrol Edge Extended Performance 5w-20 Advanced full synthetic motor oil is $29 shipped on Amazon (yes I use 5W-20 not the 0W-20 because it meets Chrysler MS 6395, and I don't like 0W-20. Napa Gold Wix filters are a deal twice a year on the Napa Filter Sale, I always buy six or so. I change the oil every 5k (the oil life gauge is usually at 20-40% left).
The 25nm torque spec on the plastic Filter cap is ridiculous. Put the new o-ring on the cap included with the filter, put a thin layer of oil on the o-ring and screw the cap back in till you feel the o-ring engage, the just give it a slight squeaky snug and you're done. I should actually measure the Newton meters once, but I bet it is less than 10nm. Filter cap always comes off nice and is never seized. Also nowhere close to snapping the nut off the top or cracking the oil cooler. I always put a big wad of paper towels to lay the cap and filter on when I pull the cap with filter. Don't remove the filter from the cap until you are over the trash can as some oil stays in there.
I also do not over tighten the drain plug at the bottom of the engine. I also always put it back in by hand and moderately snug it up. The only thing to watch is the oil really flies out if the engine is hot, so you need splash guards and to be strategic where you put the pan when draining if you don't want any on the ground. My pan has a pour spout with a cap, so I put the old oil back in the container the new oil came in and drop it off at Walmart next time I'm there. This car is also easy because it takes exactly 5qt jug.
If you get your pans and ramps squared away it can literally take 15mins to change the oil on these not moving fast. It's also pretty satisfying. Don't forget to put your car in run without the engine running to reset the oil meter by holding ok.
My last van had 350,000 miles on the same non-rebuilt engine, so I consider this process pretty good for long vehicle life. I don't think this engine is built as well as my last one(Nissan VG30E), but I've got my fingers crossed.
