Good points gentlemen. It really is all about time. I believe the more notice you have the more time to react, which increases the odds of less damage done. I ran a shop rears ago and an employee failed to refill an almost new Crown Vic with
oil. He drove it about 1 1/2 miles and burnt up the engine. He never saw the red light on the dash until the engine was making noise.
For me it's about knowing sooner than later. Is the damage just to the rod bearings or is there a rod through the block. The buzzer I have is pretty loud and annoying.
