bought a 2003 viper for the wife

the sled is very clean and runs pretty good
there are 2700 miles on the sled
the issue i have i took the sled for a 100 mile ride and the follow day i checked it over and found fuel mixed in with the oil resivor. before we burn down the motor i would like to know what caused this so it can be repaired

This should resolve your issue. There's a few options.

Make sure your gas tank is venting as it should as well. When fuel warms up it expands, when fuel is shaken it expands. Pinched/blocked/plugged vent lines will force expanding fuel down the path of least resistance.
