steve, whatever the direction of all of this speculation from the concerned fellow Viper owners/techs as to the fate of your original oil...no one can say for sure.
As suggested, you will need to monitor the oil regularly, consistantly, and carefully.
For the record, you have not supplied us with much info regarding the oil level at the time you took delivery...nor answered the question as to your driving style , break-in procedure, or schedule of same.
To an old timer, the obvious questions are: did you ever check the oil before the 1597 mile point?? If so, when and what did it show?? If you did not, it's OK...you're not the first!!
I understand you may be hesitant to admit that you "accelerated" the break-in, or imply any abuse in the process(I'm NOT saying that you did, by the way!!! )...but, in asking for help one does open oneself to a few obvious questions.
If you are really fixed on the concept that the car burns/uses oil that has not been seen, and/or you have some undisclosed reason to suspect a problem with the rings or other potentially damaged parts, visit an experienced Viper Tech...and ask him to check it out to put your mind at ease...or fix the problem.
Please take this as a constructive post...no disrespect intended.
