It's interesting that this question has come up because I am having the "low oil" light come on every once in awhile. We check the oil and its okay. It is time for the 3000mi oil change but the dealer said we could wait until the 12,000mi check up. (we use the synthetic oil so apparently can go 5,000mi instead of 3,000,i) I have 10,500mi on it now. This past summer we appeared to have no oil when we checked between oil changes, and quickly put some in. We had no "low oil" light come on then at all. It was just a sense I had to check the oil since it was soooo hot outside. My question is: Is there a sensor that comes on when it is time to change the oil - like every 3000mi and has to be turned off by the dealer? My Prius has one just thought maybe the Spyder was smart enough for one also. My 2010RT appears to use oil as well. bj
