What fuel goes in a Ford Transit?

The Ford Transit, a popular commercial van, requires diesel fuel to operate. Specifically, the Ford Transit runs on ultra-low sulfur diesel (ULSD) fuel, which is the standard diesel fuel type used in most modern diesel vehicles.


Diesel Fuel Requirements for the Ford Transit


The Ford Transit is designed to run on diesel fuel that meets the following specifications:



  • Ultra-low sulfur diesel (ULSD) with a maximum sulfur content of 15 parts per million (ppm)

  • Cetane number of at least 40

  • Biodiesel content of up to 20% (B20) is acceptable


It's important to use the correct fuel type in the Ford Transit, as using the wrong fuel can damage the engine and fuel system components. Using a higher-sulfur diesel fuel or gasoline in a diesel engine can lead to issues such as reduced performance, increased emissions, and potential engine damage.


Refueling the Ford Transit


When refueling the Ford Transit, be sure to use the correct diesel fuel pump. Diesel fuel pumps typically have a larger nozzle diameter than gasoline pumps, making it easy to distinguish them. Always check the fuel tank cap or owner's manual to confirm the recommended fuel type before refueling.


It's also a good practice to keep the fuel tank at least a quarter full to help prevent any water or contaminants from entering the fuel system, which can lead to issues like fuel filter clogging or fuel injector problems.

Should I use 87 or 89 gas?


Your car will run just fine. All modern cars can run 87,89,91,93. It's suggested that for maximum power that you use 93. If you're not at a track day event and just daily commuting 87 will serve you well. All modern cars are equipped with knock sensors to prevent engine damage from running lower octane fuel.



Is Ford Transit gasoline or diesel?


While most Transit vans will likely be sold as cargo carriers, there's also a passenger model that will seat up to 15. The Transit van has a gas engine standard, but the big news is the new diesel. This Power Stroke from Ford is a five-cylinder diesel that's been in service outside the USA for more than a decade.



What happens if I put 87 instead of 91?


If you put 87 octane instead of 91 in a car that requires it, your modern engine's computer will likely adjust timing to prevent damage, but you may experience reduced performance and fuel efficiency. For a one-time mistake, drive gently and fill up with 91 octane the next time to dilute the fuel. However, consistently using lower-octane fuel in a high-compression or performance engine can lead to engine knocking and potential damage. 
What to expect in the short term

  • Reduced performance: You may notice less acceleration and overall power. 
  • Engine knocking or pinging: This is a rattling noise that can occur when the fuel pre-ignites in the cylinder. 
  • Decreased fuel economy: Your car may use more fuel to go the same distance. 

How to mitigate the effects
  • Avoid hard acceleration: Drive gently, especially at high speeds or when climbing hills, to minimize the risk of engine knocking. 
  • Fill up with 91 octane: When your fuel tank is low, fill it up with 91 octane to mix with the remaining 87 octane fuel. This will dilute the lower-octane fuel and raise the overall rating. 
  • Check your owner's manual: The manual will specify if 91 octane is a requirement or simply a recommendation. 
  • Be cautious with performance vehicles: Cars with turbochargers or high-compression engines are more susceptible to damage from lower-octane fuel, so it is especially important to avoid aggressive driving. 



What type of gas does Ford Transit take?


The Ford Transit can take either regular unleaded gasoline (87 octane) or diesel fuel, depending on the model and its engine. Most standard gasoline models run on regular unleaded, while some diesel versions are also available. Always check the specific model's owner's manual or the label inside the fuel filler door for the exact recommendation for your vehicle. 
Gasoline models

  • Standard: Use regular unleaded gasoline with an octane rating of 87. 
  • Premium: Some high-performance or turbocharged engines may recommend or perform better with premium fuel (91 octane or higher), especially under heavy loads or in hot weather. 
  • Flex fuel: Certain models can use E85 ethanol blends, but always check the vehicle's specifications, as not all gas engines are compatible with E85. 

Diesel models
  • Use diesel fuel.
  • Ford's diesel engines are known for their fuel efficiency, particularly for long-distance driving. 

Important considerations
  • Check your owner's manual: The most accurate information for your specific vehicle is always in the owner's manual or the fuel filler door. 
  • Avoid E85 in most models: Unless your vehicle is specifically a flex-fuel model, do not use E85, as it can damage the engine and emission systems. 
  • Use Top Tier gasoline: Where available, use Top Tier certified gasoline to help keep your engine clean and performing optimally.
