Something Dad did—something I didn’t fully appreciate until after he was gone—was keep one master log book for all of his equipment. Cars. Lawn mowers. Snow blowers. Weed wackers. Anything with an engine had a place in that book.

Inside, he recorded all the important details: the make and model, the type of oil it required, when it was last serviced, and the work that had been done. Oil changes weren’t guesses. Maintenance wasn’t reactive. Everything had a history, written down in his careful handwriting.
