Is Ford e350 gas or diesel?

The Ford E-350 is powered by gasoline engines, not a factory diesel option. In North America, E-Series Econoline vans typically used gasoline V8s such as the 5.4L Triton and the 6.8L V10. Ford did not offer a factory diesel option for the E-350 in the U.S. market.


To understand how this has shaped ownership, fleet usage, and maintenance, this article details the typical gasoline engine options, clarifies the status of diesel availability, and outlines what buyers should know when evaluating an E-350 today.


Engine options through the years


The E-350’s gasoline options varied by era, with two main large V8 configurations dominating the lineup.



  • 5.4L Triton V8 gasoline engine — a long-running, common powerplant in many E-Series E-350 models.

  • 6.8L V10 gasoline engine — offered for higher payloads and heavier passenger configurations in several model years.


In short, the U.S. E-350 typically relied on gasoline V8 (and V10) powertrains rather than diesel, with engine choice depending on year and model trim.


Diesel options and market notes


Factory diesel options for the E-350 have not been offered in the U.S. market. Some fleets or individual vehicles in other regions used diesel conversions or alternative powertrains, but these were not official factory configurations for mainstream E-Series vans sold to U.S. customers.



  • No OEM diesel option in the U.S. E-350 model line.

  • Aftermarket diesel conversion kits and swaps exist but can affect warranty, emissions, and reliability; they require careful vetting.

  • For buyers seeking diesel capability within Ford’s lineup, the Transit offers diesel variants in many markets, though not as the E-350. Check regional availability and regulations.


Overall, if diesel capability is a priority, consider Transit-based solutions or alternative brands, rather than a factory-issue E-350.


Current status and buying considerations


Today, the Ford Transit is the North American successor to the E-Series for most commercial buyers. The Transit offers updated efficiency, modern safety and comfort features, and, in some markets, diesel options. If you specifically need an E-Series E-350, verify the engine in the individual used vehicle listing and be aware of potential obsolescence in terms of parts and service coverage as Ford gradually pivots toward the Transit platform.


What to check when buying a used E-350


When shopping for a used E-350, inspect the engine, transmission, exhaust, and fuel system for signs of wear or past conversions; verify maintenance history, emissions-compliance, and whether any third-party engine swaps are documented. Confirm the model year’s available engine and consult the VIN for original specifications.


Summary


Is the Ford E-350 gas or diesel? It is gasoline-powered, with common engines including the 5.4L V8 and, in some configurations, the 6.8L V10. Ford did not offer a factory diesel option for the E-350 in the U.S., and the E-Series has largely been succeeded by the Ford Transit in North America. For diesel capability, buyers typically look to the Transit lineup or consider aftermarket options with due diligence.
