Another oil question

[mcbrune]

If I check my oil after running the engine a short time it checks almost exactly at the min line, however if it's been sitting a few days and I check it's well above the max line. Does everybody's expedition suck that much oil into the system at startup? What kind of difference do the rest of you notice between the check levels when oil is in the system and when it's had time to thoroughly drain?

Thanks. Mostly I'm just trying to figure out the little traits of the expedition, but I'm also trying to ensure I have the fill level right since at the change I only put in a little less than 5 quarts.

The truck should take 6 quarts at least. I guess I have never paid that close of attention, I just add oil until it is at the top of the dipstick regardless if it was just running or not. I figure worst case it has a little extra in the system which won't hurt. Having too little on the other hand will.

My guess is it is normal that it sucks up a little less than a quart to pump to the top end.

My 05 with the 5.4 takes just about 7 qts with the filter. After an overnight sit, it is right at the high line. If I warm it up, shut it down and check the level; it is a bit lower as there is a lot of oil up in the top end of these motors. Sounds like you are experiencing similar readings?

You could follow the manual on how to check it but personally I give it about a minute after shutdown then check it and try to get it right between the top and bottom marks. If you keep an extra container or 2 you can see how much you took out so you can add the same in for starters and fill from there.

Over filling oil can cause crank splash which can cause air to get mixed with the oil ,and have a lack of lubrication . That's why there is a MAX LINE

Thanks so much for all the replies. I think I'm going to leave it. Seems to
Be below the max when cold, and right at min when hot. I'd guess it's pulling about 3/4 of a quart at startup.
