In general, the 2014 Ford E-350 uses 5W-20 motor oil for its gasoline engines, with options for synthetic blend or full synthetic. The van offered two gasoline engines that year—the 5.4L V8 and the 6.8L V10—and there was no diesel option in the U.S. market. Always verify the exact specification in the owner’s manual or on the under-hood label.
Engine options in the 2014 E-350
The 2014 E-350 was powered by one of two gasoline engines, both of which share the same basic oil viscosity guidance.
- 5.4L Triton V8
- 6.8L Triton V10
These gasoline engines use a similar oil grade, with 5W-20 as the standard viscosity. There was no diesel engine option for the U.S. market E-350 in this model year.
Oil type and viscosity recommendations
Ford's guidance for these engines centers on a light viscosity oil that protects the engine across a wide range of operating conditions. The standard and commonly recommended choice is 5W-20. You can opt for a synthetic blend or full synthetic; full synthetic is typically preferred if you drive in extreme temperatures, haul heavy loads, or want longer intervals between changes.
- Recommended viscosity: 5W-20
- Oil types supported: conventional, synthetic blend, or full synthetic
- Climate guidance: 5W-20 is standard; 5W-30 may be considered in hot climates or under heavy load, but confirm with the manual
Always confirm the exact specification for your vehicle using the owner’s manual, the oil fill cap, or the under-hood placard, as some configurations or regions may have different requirements.
How to confirm the exact specification
To ensure you use the correct oil for your specific van, consult:
- Your owner’s manual for the recommended viscosity and API certification
- The under-hood oil filler cap, which often lists the grade
- The vehicle’s maintenance portal or with a Ford dealer/service advisor for your VIN
Doing so helps avoid mismatches that could affect lubrication and warranty coverage.
Summary
For the 2014 Ford E-350 with gasoline engines, the standard oil is 5W-20, available in synthetic blend or full synthetic forms. The engines—5.4L V8 and 6.8L V10—share this viscosity guidance, and there is no diesel option in this model year. Always check the owner’s manual or vehicle placards for the exact specification and follow regular oil-change intervals to maintain engine health.
