Had something similar happen to me in my v8q -the gauge  was going spastic  
and then reading lower and lower.  Thought for sure it was the sender, but 
had the car flatbeded home free (thank you AAA Gold Plus).  My suspicions 
were right on --sender was going south.  Incidentally, The warning light is 
triggered by a pressure switch, rather than variable sending unit for the 
gauge.  You might want to check the connection to the sending unit first.  I 
believe it's at the front of the motor in front of the oil filter (how 
logical).
