* Check your owner's manual: This is the most reliable source of information. The manual will specify the exact oil capacity for your engine.
* Check the oil fill cap: Sometimes the recommended amount is printed on the oil fill cap itself.
* Look up your truck's specifications online: Websites like Ford's official website or reliable automotive parts sites will often have this information if you input your year, make, and model.
Do not rely on general answers found online, as this can lead to overfilling or underfilling, both of which can damage your engine. Always consult your owner's manual or a reliable source specific to your truck's year and engine.
