Flickering Oil Light

Time for the new puzzler. This one was inspired by a fan who wrote in with a problem in her minivan. And it just sounded like it would make a great puzzler, so here we go.

She wrote to us, years ago, and said this.

"I recently had a problem with my Chevrolet van. Anytime I stopped the van at a stop light if it was warmed up, the oil light would flicker on and off.

So I checked the oil and discovered I had plenty of oil in there. I'm becoming concerned about this happening, that I might have low oil pressure.

Oh, and by the way, I don't know if this has any bearing on the situation, but I have very little heat as well."

Okay to recap, her oil light flickers on when she comes to a traffic light, and she thinks she has low oil pressure. So, why is her oil light coming on, and what does the heat have to do with it?

Good luck.

Remember last week's puzzler?

Out To Lunch

This one was my brother's puzzler.

You could easily find the answer to this if you looked it up online. So, don't do that. That is cheating.

Here goes.

A while back, we all went out for lunch. Me, Tommy, and our producer, Dougie. It was a long day at the studio, so we went out for a bit. We finished a magnificent lunch.

So, I paid the bill and we left. When we were headed back to the studio, Tommy asked me if I left a tip for the waiter. And I said, "Yes of course. But I wonder why it is called a tip?"

So, that is the puzzler. Why is the customary practice of leaving money on the table after a meal called a 'tip'?
