Changed my oil

I changed my oil today and have a couple of questions.

Is there anything wrong with over filling your oil a little bit? I completly drained all the oil in my truck until nothing was coming out. I then added a
5qt jug into the engine.

When I poured the old oil into the jug it didnt fill it all the way. I did spill some on the ground when draining if from the oil pan.


Just curious to see if I could run into any problems.

Thanks

Jake

over filling will cause more crankcase pressure from turbulence, and can cause blowby and plug fouling from oil burning. But that said, if you don't see any smoke from the tail pipe, you are probably ok. Still, not a good thing to over fill it. How much above the full line on the dipstick is it?

My oil pressure is right where it always is. I just now that I let every thing drain from the pan and then put 5qts in.

I am thinking I will be ok.

I always use 4.5 quarts in my 3.0L.

Oil capacity:





Instead of "FULL" and "ADD" like the old dipsticks had, it is now marked "MAX" and MIN", and 4.5 quarts
puts the level right between "MAX" and "MIN" (where philips screwdriver is):

Are you talking about the stock gauge? If you then that is not a real gauge. It will only read normal or none. Basically it's an idiot light in disguise.

Crankcase pressure and oil pressure are to different things. Oil pressure is controled by the pump, engine clearances and oil viscosity. Crankcase pressure is caused by turbulence from all the moving spinning parts in the engine, and by ring blowby. It's not a goodthing, as it tends toward leaks aroung valve cover gaskets etc. and this is what the PCV system attempts to relieve.
But since you got the 4.0, You should be fine.

You are right Jake, with the 4.0L, it takes a full 5 quarts, so you didn't overfill to start with.

Just went out and checked and its right below the max/full line so I am ok.

I was just worried in the beging because I didnt think I took as much out as I put in.

A thread was started by me a couple months ago because I took my 3 liter Ranger in for an oil change and the owner's manuel says 4.5 yet the guys said 5 quarts. That is what was put in, and I was told that the manuel is wrong. As long as it isn't overfilled, which it isn't, then I'm fine.

The main problem with overfilling is when the oil level is high enough , the ends of the connecting rods dip down into the oil and cause it to airate (turn it to foam).This is bad because the oil pump is designed to move a fluid ,not air or a foamy fluid.
The result is a loss of oil pressure.

OK , All together now :
NO OIL PRESSURE IS A BAD THING

The place you took it to is run by idiots. Why would Ford print millions of manuels that are wrong.

If your truck takes 4.5qts then thats what they guy needs to put in it.

Using 5 quarts in the 3.0L will put the level to the "MAX" mark on the dipstick.
This is too close to being overfilled for my comfort, mid-way between "MAX" and "MIN" is perfect, and this is where 4.5 quarts puts the level.
