Usage Scenario

Mark was driving his truck up a steep mountain pass when he noticed the oil pressure warning light on his dash flicker. He had installed this 4-in-1 gauge last month. A quick glance at the LCD showed his oil pressure was dropping. He pulled over safely, checked the oil level, and added a quart. The alarm had given him enough warning to avoid a potentially expensive engine repair.
