I have a 2001 Wrangler w/ 6.0 automatic trans.

Ever since I've owned it when I do oil change or take it for a quicky, if 6 qts are put in (which is what it calls for) it is overfilled on the dipstick.

When I do it or take it to the guy I would normally use, we use about 5.5 qts and it is on +/- full on the dipstick. He's a certified mechanic and he has no idea why it would do that.

I wonder if it is the dipstick - if that's the case then I'm always low...

Anyone else have this problem?

The volume of oil that a particular engine will "hold" is totally and completely irrelevant.

"Why, shazamm, Goober. I done got 10 quarts in this thang, and it ain't even filled up yet!!!"

I think he meant the cylinders.. not the size.
I see…exactly 6.0 cylinders. No more, no less.

Regardless of the what the dipstick is showing, the 4.0L engine holds 6 quarts.
I have 2 Jeeps,both 4.0 & 6 qts fills them every time.I dont even ck it when Im done.

I always run 6 US quarts with a Mopar or Balwin filter and they are big, OEM size filters and hold quite a bit of oil. I don't pay much attention to the dipstick unless it's reading lower than full.

I see…exactly 6.0 cylinders. No more, no less.
Maybe it's rounded to 2 significant digits because no one wants to write 6.000327 cylinders.
