Loosing oil in 2016 SD
Going for a oil change tomorrow at 7k miles. I just looked at my oil and I’m only in the hash mark on dipstick about 1/3 of the way.
WTF did the other 2/3 of oil go? I have no leaks. Truck is a gasser with 18k miles on it. Yes, I did check the level after last oil change and it was full. Driveway is level

Correct. Guess my post is worded wrong. I think it’s more than 1/2 qt. But regardless, even if it’s 1/2 qt, why would I have lost that much oil in the first place?

Oil doesn't just disappear. It can only go a few places:
- Onto the ground (quite noticeable; common with older vehicles)
- Into the water (head gasket issue; common with older vehicles and overheating)
- Out the exhaust (leaks past piston rings into the combustion chamber, and pushed out the exhaust; you should see blue/white smoke)
- Oil was never there in the first place (meaning it wasn't filled full before)
- You read the dipstick wrong (You filled/checked the oil while on a slope; later checking level/sloped revealed different reading)

Sometimes engines use a little oil. That doesn't seem that out of the ordinary.

1/2 QT in 7,000 miles is not unreasonable when you consider the variables mentioned above. After you change the oil park it on a level place and check it after about an hour, note the level and use as a reference for future checks. I would not lose a lot of sleep over it.
If its the first oil change at 7k most new engines will use a little oil during break in.
