Old Faithful

Wyoming's punctual spout

Old Faithful is a geyser in Yellowstone National Park famous for erupting at predictable intervals—roughly every 90 minutes.

The name has become shorthand for anything consistently reliable: My old Honda is my Old Faithful.

The phrase often carries affection for dependability over flash.
