Thinking of a new gadget...

I always believed that if the oil warning "idiot light" came on, it was probably already too late and the damage was done. Hence the need for more info beforehand.
But maybe that was just referring to oil "pressure"?

Yeah, oil pressure makes sense. I really should look at the operator's guide to review the idiot dash indicators.

RE "too late": For those who care, we likely share a similar opinion. I find those who don't, drive right on with the red idiot lights and then wonder, "What happened to my vehicle?".
