The provided text doesn't explain how to put oil in an oil filter. Instead, it describes how to add oil to an engine, which is important, but different. Based on the reference, you actually don't pour oil into the filter itself when you change the oil in a car. However, there is an industry practice to pre-fill the filter. The steps for this are:
Steps to Pre-Fill an Oil Filter
While not always required, pre-filling a new oil filter before installation can help ensure quicker oil delivery to your engine upon starting. This is how:
- Locate the new oil filter.
- Locate the openings. Oil will be poured into the larger circular holes (usually several) around the perimeter.
- Pour the oil: Slowly pour new, clean engine oil into these holes.
- Avoid pouring into the central, threaded hole, as this is where the filter mounts to the engine.
- Wait Let the oil absorb into the filter media.
- Top off: Continue to pour more oil, until it’s almost full, leaving a small amount of air space.
- Installation: Immediately install the oil filter on the vehicle.
Important Note: Pre-filling is often recommended for oil filters installed horizontally or upside down. When the filter sits vertically, pre-filling is not always necessary as the pump in the vehicle will fill it when the engine is started.
Adding Oil to the Engine
The provided reference gives detailed instructions on how to add oil to the car's engine, but not the filter:
- Locate the Oil Fill Cap: Identify the engine's oil fill cap.
- Remove the Cap: Remove the oil fill cap from the engine.
- Insert a Funnel: Place a funnel into the oil fill hole.
- Refer to Owner's Manual: Consult your owner's manual to determine the correct type and amount of oil needed.
- Pour in Oil: Pour the recommended amount of oil into the funnel.
- Replace the Cap: Twist the oil fill cap back on when finished.
Why this is done: The oil added at this step is how you fill the engine crankcase, where the oil sits, and not the filter. The oil pump will then push the oil through the filter.
