How much oil does the JK's 3.8 hold?

Since the search on here is useless and I don't see the amount anywhere in the owner's manual, I'm not sure what to add.

i'd start at 5 if you were really worried, its going to take alot more than 4 qts,what idiots. Even the 3.8 minivan oil pan takes 5 qts. but remember to start the engine, let it run for a few seconds to let the oil filter fill up with oil too

Naw, not worried about it, I'll just put in the 6. I just thought it was stupid he told me to start with 4 and keep adding. Doesn't cause me to have much faith in the techs there.

As you are changing your oil, add some oil into the filter so the engine doesnt start dry. Just fill the filter 1/2 way and screw it on, use a paper towel for clean up.

this isnt really a problem for smaller filters. you can do this if you chose, but it isnt going to do a whole lot. Its when you get into bigger filters, (i.e. diesel filters), that need to be pre-filled

The filter goes in sideways, so there is only so much oil you can put into it prior to threading it on.
Just a fyi, the oil comes out under more pressure than I'm used to. When I took out the drain plug, the oil shot out WAY past the drip pan and left a nice spot on the driveway!

Not on my Jeep!

The Oil pump is at the bottom of the engine in the OIL pan

Oil filter is near mid engine area on my Jeep.

No dry start there.
