* Check your owner's manual: This is the most reliable source. The manual will specify the exact oil capacity for your truck's engine.
* Look for an engine code: The engine code (like a 4.6L, 5.4L, etc.) is usually found on a sticker under the hood or on the engine itself. Once you find the engine code, you can search online for the specific oil capacity for that engine.
Without knowing the specific engine, I cannot give you a precise oil capacity.
