B7 diesel fuel, also known as B7, is a blend of diesel fuel that contains up to 7% biodiesel. Biodiesel is a renewable, biodegradable alternative fuel made from modified vegetable oils, animal fats, recycled greases, or yellow grease (used restaurant oil from cooking). B7 diesel has been the standard diesel grade in the EU since 2011 and is used in all diesel vehicles, although France has recently permitted the sale of B10 diesel fuel. Biodiesel blends offer a compromise between the environmental benefits of biodiesel and the performance characteristics of standard diesel fuel. B7 diesel reduces tailpipe emissions, including soot and air toxics, and has a lower emissions profile than conventional diesel fuel.

What You'll Learn
B7 diesel is a blend of normal diesel and biodiesel
B7 diesel is a blend of biodiesel and conventional diesel fuel. The "B" in B7 indicates that it is a biodiesel blend, while the number 7 indicates that biodiesel makes up 7% of the total volume.
Biodiesel is a renewable biofuel derived from biological sources such as vegetable oils, animal fats, or recycled greases. It consists of long-chain fatty acid esters and has distinct lubricating properties. The modern form of biodiesel emerged in the 1930s with the discovery of a method to transform vegetable oils for fuel use. Today, biodiesel is often blended with conventional diesel fuel to create more sustainable fuel options.
B7 diesel is a relatively common blend, with the UK and Germany mandating its use in transportation fuel. It is also known as FAME (Fatty Acid Methyl Ester) diesel, indicating that it contains up to 7% of this substance. This blend is suitable for use in all diesel vehicles, according to the ACEA (European Automobile Manufacturers' Association).
B7 diesel offers a compromise between the environmental benefits of biodiesel and the performance characteristics of standard diesel fuel. While biodiesel on its own has lower energy content per gallon than conventional diesel, B7 blends strike a balance to maintain fuel efficiency. Additionally, biodiesel blends can reduce tailpipe emissions, including soot and air toxics, and have beneficial effects on engine deposits.
B7 diesel is part of a range of biodiesel blends, with other common blends including B5 (up to 5% biodiesel) and B20 (6% to 20% biodiesel). These blends aim to balance the advantages of biodiesel with the compatibility and performance of standard diesel fuel. B7 diesel, therefore, represents a step towards more sustainable fuel options without requiring significant modifications to existing diesel engines and infrastructure.

B7 diesel contains up to 7% biodiesel
Biodiesel is a renewable biofuel derived from biological sources like vegetable oils, animal fats, or recycled greases. It is typically blended with petrodiesel to varying percentages, with B100 representing pure biodiesel. B7 diesel, as the name suggests, contains up to 7% biodiesel. This blend is commonly used in many countries, including the UK, which has mandated its use, and the 27 member states of the EU, where its sale has been mandatory since 2011.
The "B" in B7 diesel represents the biodiesel component, while the number indicates the percentage of the renewable element in the blend. B7 diesel is considered normal diesel and can be used in all diesel vehicles without requiring engine modifications, as is the case with higher biodiesel blends. This makes it a popular choice for fleet and commercial vehicles, as it balances cost, emissions, cold-weather performance, and compatibility with conventional engines.
The use of B7 diesel offers several benefits. Firstly, it is derived from renewable resources, reducing dependence on foreign oil. Secondly, it provides environmental advantages by reducing tailpipe emissions, including carbon monoxide, particulate matter, and net carbon dioxide emissions compared to conventional diesel fuel. Additionally, biodiesel is non-toxic and biodegradable, making it the preferred fuel type for the US government and its military.
However, it is important to note that the environmental impact of biodiesel is complex. While it can reduce greenhouse gas emissions compared to fossil fuels, there are concerns about land use changes, deforestation, and the competition between food and fuel production. Nevertheless, B7 diesel blends offer a compromise between the environmental benefits of biodiesel and the performance characteristics of standard diesel fuel.
The adoption of B7 diesel is supported by policies and incentives in some countries. For example, the UK's Renewable Transport Fuel Obligation (RTFO) targets a blend of renewable fuels in the fuel supply, and tax incentives like the Bus Service Operators' Grant (BSOG) encourage biodiesel use. These measures aim to increase the use of biodiesel and promote sustainable energy practices.

B7 diesel is safe to use in all diesel vehicles
B7 diesel is a blend of diesel fuel that contains up to 7% biodiesel, also known as Fatty Acid Methyl Ester (FAME). This type of fuel has been mandated for use in the UK and across the 27 member states of the EU since January 1, 2011.
B7 diesel is considered safe to use in all diesel vehicles. In fact, it is often referred to as "normal diesel". This is because the percentage of biodiesel in B7 is low enough that it does not require separate labelling at the pump and can be used in most engines without modification. Biodiesel blends up to B20 (20% biodiesel) can typically be used without any issues, and many diesel engine manufacturers approve the use of B20.
While B7 diesel is safe for all diesel vehicles, it is important to note that using higher blends of biodiesel, such as B100 (pure biodiesel), may require engine modifications and can impact engine warranties. Additionally, B100 can have a solvent effect, cleaning a vehicle's fuel system and releasing deposits accumulated from petroleum diesel use, which may initially clog filters.
The benefits of using biodiesel blends include reduced tailpipe emissions, such as soot and air toxics, and a reduction in carbon monoxide and particulate matter emissions. Biodiesel is also renewable, biodegradable, and derived from biological sources like vegetable oils, animal fats, or recycled greases.
