A single handed oil filter puncher tool system and method that operates as an easy and simple time saving device for draining an oil filter during vehicle service with single hand operation. The system is a puncher tool assembly having a handle at a proximate end a perpendicular guide shaft. The tool further includes a sliding punch assembly and an outer sliding sleeve that work together in functional combination as a moving assembly that gets cocked into place while compressing a driving spring. An activation lever releases the sliding punch assembly from the cocked position causing the driving spring to unleash force on the sliding punch assembly. The sliding punch assembly slides along the guide shaft forcing a piercing pin into an oil filter in a single handed operation. The piercing pin punctures the oil filter causing it to drain.
