Car warning lights

I fully admit that I tend to ignore the idiot lights on my dashboard. Check engine? Why? It's running fine but a mechanic will surely find something wrong which be a harbinger of an impending nuclear explosion in your engine if you don't get it fixed now! Oil pressure light on? Check the oil; if it's okay  and again, the car is running fine, ignore the warning. The dashboard warnings are there at best as clues to the vague chance that something is wrong, not omens of dire consequences.

Yet I must concede that I was, well, not exactly taken aback this morning as intrigued. My eyes saw the warning, and I'm sure my head went to side to side as a dog's might when contemplating an unknown. Where my odometer, mileage reading, should have been was instead the word gascap.

My first thought was that I have one of those, yes. It fits over the end of the gas tank tube. But still, when I got to the Shop I checked it. It was secured tightly.

The warning came back on when I restarted the car awhile later. Hell, I thought. Another thing I gotta learn to ignore. About the worst thing is I won't know when to get my oil changed now.
