Checking Engine Oil Dipstick...Quick Question?

Alright guys so after some driving today I shut the truck off and checked the oil after 20 min, and it reads to the top of the "x" on max (almost to the top of that whole bubble). By subtracting what oil was left over I discovered I used 13.5L, with an oil filter on my last oil change, which I though was correct.
So what should I do guys, just leave it, or get under there and drop some oil out? Also, on cold starts, the truck smokes blue for about 2-5 seconds. Its not heavy, thick blue smoke, however there is enough to notice a bit of blue. Could this be the cause of too much oil? If so I will be draining some. It does not do it if it wasn't very cold overnight.
Thanks guys.

Follow up.
Please read why they are doing this. If your engine is making oil, (aka failed injector) this allows you to diagnose. Your post is probably 100 % correct. But the short stick method will help you to save your engine. Again, you chose.

Great post rmosso! Never saw that TSB but it provides a good way of checking for an overfull condition.
The most important thing using this method is recognizing that the full level is only halfway between the MIN and MAX markings. If you short stick it and it's reading at MAX you're way overfull!
Thanks for posting that!

Months ago there was a guy on here named Bobby Light. He runs/maybe ran, with the times, a fleet of 60 trucks PSDs. He really knew his stuff. I have not seen a post from him in some time, but I did learn a lot.
I hope the guy still has his job and comes back to FTE. Always neat to have an expert on staff.

P. S. On all the posts I ever read about the 6.4, no one ever seemed to worry about burning oil. Always there was too much oil/fuel oil in the crank case. Just as follow up.

Try smelling the smoke to determine if it smells like diesel or oil, the 2 are very distinct and different. This should give you a good indication of what is burning.But unless I see a big increase in oil level (meaning raw diesel fuel getting in the oil) or a big decrease in motor oil (meaning oil is being burnt off or leaked out) I wouldn't get to worried. As stated just keep checking every tankful. And try the short stick method to tell if it is moving up or down.

Alright so I tried the short stick method and it is at the correct level. Now why exactly would fuel be filling the crankcase? Also, is this theory the same for my 6.0l ?

Injectors do/can go bad and they can load up the cylinder and bypass the rings, filling the crankcase with fuel in ALL Diesel motors. With the bulb style “Dipstick” you cannot detect a problem until it’s too late. Yes the 6.0 has the same problem. ******* Dipstick Design! From what I understand the 6.7 has the old tried and true dipstick.
