Default Z06 -- oil leak(s)

Need some help. Car has 350 miles on it. First time for warm weather here and drive it yesterday twice ; going back in the garage the second time notice a 3" diameter black spot on floor ---- location: would be to the left of the differential ; substance is a somewhat clear fluid --- some type of lubricant/oil.
Park vehicle ; put a newspaper down under the differential ; check in an hour or two ; NOTHING ; however ; some oil has leaked at the right FRONT of the engine. Put newspaper in that spot also. This morning there is not any leakage anywhere.
Dealership (have not yet worked on a '15 Z06) is backed up until next Tuesday plus I am headed for Sebring.


Thoughts? Thanks.

Hope for too much engine oil! If so it will leak from the air filter due to the suction and pressure of supercharger boost drawing it out. Or it could be a differential seal where the small circular spring in the seal breaks and will let gear lube sweat out. Had both happen to my supercharged C6Z years ago.

Are you certain front leak is oil? Might be A/C condensation. No idea on rear leakage.

Thanks for the input ------ at front is oil ; at rear the question is just where did it come from?

(will update this ; has leaked at the front before and then it does zero for multiple days of sitting --- the oil filter overflow makes sense.)

Interesting. I had mine up on the lift today and it looks like they used liquid filled mounts for the transaxle just like the engine mounts. That would be in the vicinity you are describing and one of mine appears to be leaking. It's a small cylinder covered in a metal case with a couple holes in the bottom. Mine shows what looks like a liquid (and accumulated dirt) around one of the holes.

I'm heading to Summit Point this weekend and then to Spring Mountain so it'll be a while before I can get the car to the dealer to get looked at.

Good luck and hope it's nothing. Are you driving the z to Sebring? I'm driving our new blade silver z, headed out Wednesday and should arrive Thursday mid day.
