Which option is NOT a method to dispense oil?

Hand packing is not considered a method to dispense oil in the same way as the other options. Hand packing typically involves manually applying grease or lubricant to a component, such as filling bearings or housings. This method relies on the physical effort of the operator and does not utilize a specific dispensing mechanism.

In contrast, the other methods listed—single point, self-contained splash gun, and automatic lubricator—are all designed to systematically dispense oil. A single point lubricator provides a controlled delivery of lubrication to a single point. The self-contained splash gun allows for dispersing oil through a spraying or splashing action, while an automatic lubricator delivers a consistent supply of lubricant over time, often using automated timers or sensors to keep lubrication levels optimal. These methods focus on efficient and consistent dispensation, which distinguishes them from the manual nature of hand packing.
