I drove 85 freeway miles with no visible smoke, even when I stopped at lights nothing visible with temp and power looking and feeling great. I parked it and came back 2 hours later and the initial smoke again but performed fine. When I returned home I plugged it into the computer and it came back with both O2 sensors being bad. Then I check the oil and it was essentially gone, barley registered on the stick. No visible oil leaks underneath. Did I burn through it all? Do I have an RMS issue? I've parked it since. Thanks for any help you can provide.

Your oil was likely not essentially gone. Not registering and no oil are completely different. Why did you "plug it into the computer"? You never mentioned seeing a CEL?
Are there any oil soaked areas under the car?
How much oil did you use for the fill?
And yes you do have a Rear Main Seal (RMS); whether or not it's leaking remains to be seen. The first step is to look at the underside of the car!
