What does B20 mean on Ford trucks?
B20 is a diesel fuel blend consisting of 20% biodiesel and 80% petroleum diesel, and many Ford diesel trucks are approved to run on this blend when it meets required standards. Check your model year and Ford’s official guidance to be sure about compatibility.
Understanding B20 and biodiesel blends
Biodiesel blends are made by mixing biodiesel with conventional diesel. The number in BXX denotes the percentage of biodiesel in the blend. In the case of B20, the fuel contains 20% biodiesel and 80% regular diesel. Biodiesel must meet established standards to be used in engines and fuel systems designed for blends like B20.
- 20% biodiesel and 80% petroleum diesel.
- Typically must meet ASTM D6751 specification (and the petroleum diesel portion must meet applicable standards).
- Most commonly produced from renewable sources such as soy or other vegetable oils and used widely in fleets and passenger vehicles that claim B20 compatibility.
Understanding these basics helps determine whether your Ford truck’s diesel engine is prepared to handle B20 and what conditions may apply for safe operation.
Ford trucks: B20 compatibility and guidance
Ford provides guidelines on biodiesel usage for its diesel engines, which generally include compatibility with blends up to B20 under specific conditions. Always verify with your owner’s manual or a Ford dealer for your exact model year and engine configuration.
- Many modern Ford Power Stroke diesel engines are designed to tolerate blends up to B20, provided the biodiesel meets applicable standards.
- Compatibility can depend on model year, engine type, and the fuel system design; some older engines may have stricter limits.
- Ensure the biodiesel meets ASTM D6751 and that any fuel used is Winterized or treated for climate conditions if you operate in extreme cold.
- Using biodiesel blends outside the approved range or without proper certification can affect performance and may impact warranty coverage.
- Always follow Ford’s recommended maintenance practices when using biodiesel blends, including monitoring fuel filters and fuel system components.
In practice, Ford owners should treat B20 as a supported option only when it aligns with the official documentation for their vehicle, and they should source biodiesel from reputable suppliers to meet the required standards.
Practical tips for Ford owners considering B20
Before switching to or confirming a B20 supply, consider these steps to ensure compatibility and performance.
- Check your vehicle’s owner’s manual or contact a Ford service advisor to confirm B20 compatibility for your exact model and year.
- Look for fuel door labeling or fuel system notes that specify acceptable biodiesel blends for your truck.
- Use biodiesel that meets ASTM D6751 standards and ensure the blend is appropriate for your climate (winterized biodiesel in cold weather).
- Monitor for signs of fuel system issues or performance changes after switching blends, and have filters inspected or replaced as recommended.
- Be aware that using biodiesel blends outside the approved range or without proper certification could affect warranty coverage.
By following official guidelines and using high-quality biodiesel, Ford truck owners can take advantage of B20 while maintaining engine reliability and fuel system health.
Summary: B20 means a 20% biodiesel and 80% petroleum diesel mix. In Ford trucks, many modern diesel engines are approved to run on B20 when the biodiesel meets industry standards and the vehicle’s documentation allows it. Always verify compatibility with your specific model year and engine, source biodiesel from reputable suppliers, and monitor vehicle performance and maintenance requirements accordingly.
Is B20 better than regular diesel?
Engines operating on B20 have similar fuel consumption, horsepower, and torque to engines running on petroleum diesel. B20 with 20% biodiesel content will have 1% to 2% less energy per gallon than petroleum diesel, but many B20 users report no noticeable difference in performance or fuel economy.
Is B20 the same as diesel #2?
No, B20 is not the same as diesel #2; B20 is a blend of 20% biodiesel and 80% diesel #2, while diesel #2 is pure petroleum-based diesel. Diesel #2 is the standard fuel, and B20 is a blend that incorporates biodiesel to achieve benefits like reduced emissions and improved lubricity.
| Feature | Diesel #2 | B20 |
|---|---|---|
| Composition | Pure petroleum-based diesel | 20% biodiesel and 80% diesel #2 |
| Emissions | Higher particulate matter, carbon monoxide, and hydrocarbon emissions | Reduced emissions, particularly for older engines, including lower particulate matter, carbon monoxide, and hydrocarbons |
| Lubricity | Less lubricity | Superior lubricity |
| Energy Content | Higher energy density (more energy per gallon) | Slightly lower energy density, which can result in a minor drop in fuel economy (1-2%) |
| Engine Compatibility | Compatible with all diesel engines | Compatible with most modern diesel engines without modification |
| Cold Weather Performance | Performs better in low temperatures | May gel in very cold temperatures without additives |

Can you run regular diesel in a biodiesel truck?
Yes, you can run regular diesel in a biodiesel truck. Most modern diesel engines can switch back and forth between regular diesel and biodiesel blends (like B20) without issue, as they are essentially the same engine type. However, it is always best to check your engine's manufacturer warranty and recommendations to be sure, especially when using higher blends of pure biodiesel (B100cap B 100𝐵100).
Important considerations
- Biodiesel blends: Standard diesel engines are designed to handle biodiesel blends like B20 (20% biodiesel, 80% diesel) and B5 (5% biodiesel, 95% diesel).
- Compatibility: All modern diesel trucks are physically compatible with both regular diesel and biodiesel fuel blends. The main difference is the source and chemical properties of the fuel.
- Engine warranties: Check your vehicle's warranty to confirm its stance on higher blends of biodiesel (above B5), as some manufacturers may not approve their use.
- Cold weather: Regular diesel performs better in cold temperatures than higher biodiesel blends, which can gel in cold weather.
- Fuel system components: Biodiesel can improve lubricity, but high concentrations may require more frequent filter changes because of its ability to clean out deposits.
- Upgrades: Some systems are available to allow a truck to run on 100% biodiesel, even in colder weather, by using a special upgrade with a heated fuel tank and a system to automatically switch between diesel and biodiesel.
