Slant 6 oil pressure woes…

I guess I'm just not understanding how on Earth you cannot read the level on the dipstick.
Well now that the morning has come, I’ve checked it again, and the oil level sits just below the full line. Before I drove it yesterday it was just above the full line. So the oil level hasn’t changed a lot, so I’m thinking the oil leak isn’t all that severe. Im headed to the store right now but when I get back I’ll be checking the flammability of it as suggested above. At this point I have no clue what’s going on. Unless the oil is leaking and it’s just being replaced by gas that quickly. It is pretty clear on the dipstick. Like I said I’ll be checking the flammability later. Will update you soon.
