I'm putting up the BS flag for anyone saying their truck (or any car) isn't dropping oil.
90% of the guys on here don't change it themself anyway to know!
Plus the following occurs:
Not really measuring what is coming out...just dumping and pumping.
Having truck jacked at the wrong angle and not dropping all the oil.
Not working on a cold sat engine where the oil is collected in the pan.
Not putting in the right amount to start with.
Oil blow-by
Burning excess
Towing
7 qts in and loss by any/all of the above......guaranteed. Your truck is gonna have loss no matter what.
Do a complete drain and measure it each time to find out what the loss really is. (Tilt truck correctly to get all fluid to the drain hole, let the mass drain, plug the hole, let it sit for a good length of time, open and drain again..twice. Measure the old oil in the same jugs the new oil came in.)

What many may be saying or at least I am saying is my hemi does not use enough oil between oil changes to significanly show a drop when checking using the dipstick. Do I get 7 quarts out. No. Did the hemi burn/drop some oil in the 3K. Most likely. Can you get 100% of the oil out during a change. Don't think so.

From my experience and information from my dad who has been a mechanic a long time, most cars use b/n 1/2 -3/4 Qt of oil per 3-4K miles and it's normal. with that said, if you warm the oil up, let it sit for 20 min., measure, drain and measure, you will not drain all the oil out of the motor, many spots oil is left that add up to vol. along with whats soaked into the oil filter. As long as your motor is not leaking oil, blowing blue smoke out the back, theres not a problem, also have to remember these motors don't work like traditional motors.

I have 22K on my 09 hemi and it does not burn any oil at this time. I change the oil myself and I always check the level before I drain to monitor consumption with all of my vehicles. Check and make sure that you don't have a leak somewhere. You can change back and forth between mineral and synthetic anytime. What do you think a blend is?? It is true that if you have a leak that a synthetic will leak more because the waxes that are still in the refined mineral base will clog a leak, just like they do your oil galleys and passages with time. 5W-20 is pretty thin as it is, look for leaks.

I have when I changed the oil and there is absolutely no leaks. Now I will say now that I think about it my street might have been level or when I checked my oil the garage I was in was not level. Its not alot, at all. Its like less than a 1/4 inch.

Not sure your point. What does changing your own oil have to do with checking to see if the engine has consumed oil? There is an oil dipstick. It is used to check the oil level.
HUH? You are kidding me right? You can't trust the dipstick, nor the operator of the dipstick in checking the oil properly with a dipstick. The dipstick gives a range of oil actually hitting the indicator...not a consumption rate. You are assuming the range is always the same...I won't even get into this one really. Changing your oil and verifying levels and checking the dip level is completely different.

There is a HUGE learning lesson for you next time you actualy change it....MEASURE IT. Do not trust the dipstick...No pun intended. You will be surprised.
