The 2013 Ford F-150 that uses the common 6-speed automatic (6R80) typically requires Mercon LV automatic transmission fluid. Use a Mercon LV ATF from Ford Motorcraft or any brand that meets the Mercon LV specification, and verify your exact requirement in the owner's manual or on the transmission dipstick label.
Recommended fluid for most 2013 F-150 models
The following options cover the fluids that meet the Mercon LV specification, which is the standard for most 2013 F-150s equipped with the 6R80 automatic transmission. Always confirm the exact spec for your vehicle before buying.
- Ford Motorcraft Mercon LV ATF
- Castrol Transmax Mercon LV
- Valvoline Mercon LV
- Mobil 1 Full Synthetic ATF (Mercon LV specification)
- Royal Purple Max ATF (Mercon LV specification)
These fluids are designed to meet Ford’s low-viscosity Mercon LV requirements and are commonly available at automotive retailers or through dealerships. If your vehicle has a label or manual indicating Mercon LV, these options are appropriate. If a different specification is shown, follow that exact requirement.
How to verify the exact specification for your truck
Because Ford has used different fluid specs across trims and production years, it’s important to confirm the precise requirement for your individual truck. The steps below help you verify the correct ATF specification.
- Check the owner's manual or Ford’s official service information for your vehicle’s VIN.
- Inspect the transmission dipstick or the transmission fluid cap for the exact specification (e.g., Mercon LV).
- Consult your dealership or a trusted mechanic if the manual or labels are unclear or missing.
Confirming the exact specification ensures you don’t misapply a fluid that could affect shifting performance or longevity. If in doubt, choose Mercon LV and avoid older Dexron or Mercon V unless specifically required.
Maintenance tips and notes
When replacing transmission fluid, follow best practices to protect the six-speed automatic and its transmission fluid system. The guidance below helps ensure a proper service.
- Use only fluids that meet Mercon LV or the exact Ford specification listed for your vehicle.
- Do not mix Mercon LV with older Dexron III or Mercon V fluids unless explicitly approved for your model.
- If performing a full drain and fill, consider replacing the transmission filter (where applicable) and inspecting the pan for debris.
- A full fluid change can require more fluid than a simple drain-and-fill; have extra fluid on hand to reach the correct level.
After completing any transmission service, test drive the vehicle to ensure smooth shifting and proper transmission behavior. If shifting feels harsh or delayed, consult a professional to verify fluid type and level.
Summary
For most 2013 Ford F-150 models with the 6R80 automatic transmission, Mercon LV automatic transmission fluid is the standard requirement. Always verify the exact specification in your owner's manual or via the VIN-specific service information, and use a Mercon LV-compliant ATF from brands such as Ford Motorcraft, Castrol, Valvoline, Mobil 1, or Royal Purple. When in doubt, consult a dealer or qualified technician to confirm the correct fluid type before performing a service.
