Seriously though, I run K&N filter or Napa Gold with whatever synthetic national brand oil thats on sale at the time. This oil change consists of Synthetic Quakerstate. Time before was Mobil 1. Who knows what brand will be on sale next time
It doesn't matter. Just run any reputable brand (Mobil, Valvoline, Castrol, Amsoil, etc) that you have at your local walmart, and get whichever one is on sale. Do NOT buy Royal Purple.

Since the motors take 6 quarts, do you guys usually buy one 5 quart jug and one matching 1 quart bottle?
Also, when I did my own oil change this past weekend, the dipstick showed full after 5.75 quarts, so I didn't bother putting the last quarter quart in, figuring that a little bit simply didn't drain out (Jeep was parked on flat ground, and I let the oil drain until no more dripping). Do you guys experience this?
It varies with filter size and time allowed to drain. Plan your oil change and do it in the morning before you start for the day if you really want a full six qt change
From what I understand, cold oil is more viscous and it's likely that a bit more will stay inside the engine if you try to drain it in the morning. Also, I heard that the contaminates in the oil settle when the engine is cold and some will stay inside the motor or pan.
More oil will come out if it's hot, since it flows much better and is less likely to stick to the walls inside the engine. Of course, some will always stay "stuck" inside the ports, pump, etc. no matter when you change it.
remember if you're not opening and removing the oil cartridge BEFORE you open the drain plug, you're not getting all of the old oil out...this, oil temp and time you let it drain can affect how much it takes to get the level to full on the dipstick. IIRC I let mine drain for over an hour (Very hot oil) and still had oil dripping out of the pan at a frequent drip rate.
When ever I buy a new or used vehicle, the first thing that I do is replace whatever oil/filter that is in the car/truck with Mobile 1 or AMSOIL, plus filter's.:thumb:
For you scientists out there with no personailty, I was being fececious. Hoe the F in the right mind is gonna expect all 6qt to drain out under most circumstances with an oil change. Also, who the F is gonna leave there vehicle to sit for and hour plus with the drain plug out waiting for the oil to stop dripping. Sometimes you folks are ridiculous. PS, there are about fifty other threads that also argue brand and procedure already. To the OP; use a new oil of your preference and within your budget. Even conventional oils, if you desire to use, can give great protection for your jeeps engine. Mobil 1 is popular and well advertised, great product. Use what you want, just be vigilant to drain it out when its time and you wont have any oil related engine failures. To the smartie that said his filter is a canister type and does not vary in size, no kidding. I was writing generically speaking regarding reasons capacity can vary.
I do. I do it on a cold motor (all the oil is in the pan), set up the drain pan, undo the drain plug, and go about my day, letting the oil drain all day. Then, I come home, put the drain plug back, fill her up, and that's all she wrote. If I am in a hurry, I'll do the oil change another day. It's just OCD. There is no need for that. When the drain is dripping less than one drop every 10 seconds, go ahead and put the bolt back in, and fill to the correct level.
Well....I had time to burn this past Sunday morning......so I let the oil drain for about 80 minutes to get out as much of the spent oil as possible. I don't do work on my vehicles unless I have time to spare....you never know when something might break....but that's just me.
