I drained the oil, changed the filter and added 1 gallon of Rotella 10/30.
An hour later I checked the level and the dipstick was covered to the top.
I checked it again today and the same thing.
I drove to work and back and checked​ 20 minutes later and the same thing.
No discernable oil pressure reading from before changing.
WTF?

Most "gallon" jugs are five quarts these days...

Was the car level or nose up when you drained the oil?

Tommy: Sounds like a filter problem. Any noises from the little 4???? You may have an incorrect length oil filter. You have not stated. What is the operating temp? Don't run it till we all chime in on this.

Do you mean that there is no discernable oil pressure or that the oil pressure is goid but no discernable difference from before the oil change?

If you have good oil pressure, but the level is too full, just drain a bit out.

Purolator pl20195 as usual
Rotella not 20/50
Level ground
No change in oil pressure
It is the oil being on the length of the dipstick that concerns me.
Just checked again, same thing.

Well if only you had refilled the Rotella container with what you drained out.

Sure you have the correct dipstick? I just measured mine and it's 11" total from the rubber stopper to the end of the stick. 9" to the MAX line.

If the oil is all the way up the dipstick, you have too much oil in the engine. Are you sure you only put in four quarts, or did you empty a five-quart jug into the engine?

For some reason Rotella and some other oils for diesels comes in one gallon jugs instead of 5 quart.

Do note that a quart is about equal to a liter, which translates to about 60 cubic inches. If the deep part of the sump is, say, 10 inches by 10 inches, then it has an area of 100 square inches. So adding an extra quart of oil would only raise the level in this part of the sump just over a half inch. And if you added still more oil, such that the oil now filled both the deep part of the sump, and also the shallower area, the change in depth by adding yet another quart of oil would only be about a third of an inch. So it would take quite a bit of oil to completely fill the sump, which is highly unlikely.

Seems to me the logical next step would be to drain the oil to see how much comes out...

Tommy, did you drain the transmission, then add oil to the crankcase?

Tommy,
What did you mean dipstick was "Covered to the Top"?

Also, you need to use a heavier oil, 10/30 is on the light side.

On my B, replacing the oil filter and draining the oil cooler, I use about 4.3 US Quarts to the full mark.

Note the min to max lines on the dipstick is 1 imperial pint or 20 imperial ounces or 19.2 US ounces, not a quart (of any type)

In the past there has been discussions about the various dipsticks and dipstick-tubes. Moss list 3 dipsticks and 2 tubes, the combination matters.

I was wondering the same thing?

The very first time I ever changed the oil in my first car I was 15), I did just that. I drained the transmission fluid and then dumped in five quarts of fresh oil on top of the old oil.

The oil sump plug is at an angle and that is where I drained - it is very clean, ha ha.
Gearbox oil is good as I just checked it.
I will drain the engine oil in the am as I have another gallon of Rotella.
