I use a washing machine overflow pan as a drip pan with a drain pan on top. They have them at Home Depot or other such home places. It has a perfect height lip that will catch all your messes, but still allow you to reach around it. It is acceptably huge, but still fits between the wheels of any car, truck, SUV, or Jeep. It is also cheap.
Good thought on the reason being 5W20.
And good info right from a valid source. You were there; you would know.

One of those nice to know things...............I dislike cleaning up my garage floor. The first time I changed the oil in my Ram 5.9 diesel I just about choked........what is it...13 litres of oil in that engine? Anyway after removing the oil pan nut and watching a black Niagara Falls.........I looked at the pan and just prayed that it wasn't going to overflow...........in the end I think the flow stopped about a 1/2 inch from the top of the pan.......whew. Black sooty oil over my garage floor would have set me off lol.

Hey...over 7,000 hrs on the C-130 (Green Go - Load Smasher)

So..........after reading this thread I'm better prepared for my first JK oil change................it only has 1,500 mi on it now.

There can't be any pressure in the oil pan.............with the dip stick venting it..........and the oil cap removed?

Yeah I know the oil pan was not under pressure, I am sure it was due to the 5w-20 weight and it being 6 quarts instead of the normal 4 (in my old pickup 3.9 dodge) or my 5 quarts in my wifes Van.

LOAD CLEAR...

Ah, but there IS pressure in the oil pan. The pressure created by the weight of the oil above the drain hole, as evidenced by the fact the oil comes out horizontally for a short distance at first.
Really though, I don't think any one was saying the oil pan was pressurized. All that was said is the oil came out as if under pressure; which it does.
(52000 hours working on KC-135's, and counting.)

Just did the 1st oil change on my 08' @ 5000mi.
Had the same problem with the oil filter, had to use my super strength to get it off! Then the gasket was stuck on the block.
Oil pressure wasn't that bad I have a big drain pan and allways position it towards the back, for just such an occasion.

1st time post, love this forum!

Aha! I had one of those. Backed out of the garage the morning after delivery (and the 53 mile drive home) and had 2 qts of oil under the Jeep. At first I thought "Schnikees - it's dead already!" Then I got a hold of myself and grabbed the filter. It came off in my hand.

That robot should be outsourced...

I just wanted to reiterate what others have said about the gasket on the stock mopar filter from the factory. After I got it off the gasket was still stuck to the machined part of the block They seriously need to lube these things.

Hey JulietKilo,

Looks like this is somthing that alot of us JK owners have come across. I changed my oil at 1000 miles for the first time.

Now, you got to remember I have been changing my own oil for longer than you have been alive. I had to work very hard to get that stupid filter off. And like you, I then needed to get the gasket off.

Looks like something Jeep may need to look into......

I signed a confidentiality contract when I quit. I don't mind adding info when I can, but I won't sponsor threads or give away things about the process that I shouldn't. Honestly, I have very little data that many thousands of factory workers in North America don't already know.

I bought a Dodge Omni new. The original filter was so tight, and the gasket so smashed, the metal of the filter contacted the block around the outside of the gasket. The screwdriver trick wouldn't touch it. I gutted the entire filter and chiseled the end cap off. It took me an hour to get the filter off. Oddly that car used the same filter as the JK.
