What You'll Learn
Use blends of high-quality biodiesel fuels
Using blends of high-quality biodiesel fuels is an effective way to save energy at home with diesel fuel. Biodiesel blends are available in varying concentrations, with the most common being B5 (up to 5% biodiesel) and B20 (6% to 20% biodiesel). B100 (pure biodiesel) is also an option but is less commonly used as a transportation fuel due to regulatory and pricing issues.
Biodiesel blends offer several advantages for energy savings. Firstly, they are compatible with all available diesel models. Most diesel engines can accommodate blends of up to 20% biodiesel (B20) along with 80% regular petroleum diesel. This compatibility means you can easily switch to biodiesel blends without needing to modify your existing diesel engine.
Biodiesel blends provide energy efficiency and environmental benefits. While B20 blends have slightly less energy per gallon than petroleum diesel, many users report no noticeable difference in performance or fuel economy. Additionally, biodiesel improves fuel lubricity, which is essential for preventing premature wear in diesel engines. The lubricity of biodiesel also addresses the issue of reduced lubricity in modern diesel fuels due to lower allowable fuel sulfur content.
Biodiesel blends also contribute to reducing greenhouse gas emissions and other toxic emissions. The emissions benefit is roughly proportional to the blend level, so a B20 blend would provide 20% of the emissions reduction benefit of a B100 blend. Biodiesel is also safer to handle, store, and transport than petroleum diesel due to its higher flashpoint, making it less combustible.
By using blends of high-quality biodiesel fuels, you can save energy at home by taking advantage of their compatibility with diesel engines, their energy efficiency, their positive impact on engine maintenance, and their contribution to reducing emissions and improving overall energy security.

Reduce drag with vortex generators, fairings, and wheel covers
Diesel engines are widely considered to be more fuel-efficient than their gasoline counterparts. However, there are always ways to improve fuel efficiency and save money. One of the most effective ways to do this is to reduce drag.
Vortex generators are one such method to reduce drag. They are a type of aerodynamic device that can be installed on the front of a vehicle, often a truck or freight train locomotive, to reduce the amount of drag. Vortex generators work by generating a vortex in front of the vehicle's wheels, which suppresses the wake formed along the side of the vehicle, thereby reducing drag. This wake suppression helps to improve fuel consumption and, as a result, saves money on haulage costs.
Fairings are another drag-reducing device. These are covers that can be placed over the wheels or other areas of the vehicle to streamline the vehicle and prevent air from stagnating, which causes drag. Fairings can take many forms, including nose fairings, mirror fairings, roof spoilers, and side skirts. Each type of fairing is designed to minimise drag by streamlining the vehicle and preventing air stagnation. For example, a mirror fairing guides the flow of air around the mirror, reducing flow separation downstream. Similarly, a primary fairing can cover vertical stanchions and ditch light fixtures, eliminating them as drag sources and reducing stagnation near windshields.
Wheel covers are another simple way to reduce drag. Attaching covers over the wheels of freight trains has been shown to decrease drag by around 25%. Wheel covers work by streamlining the wheels, which are often a source of drag due to their shape and movement. By reducing the drag caused by the wheels, the vehicle becomes more fuel-efficient.
Overall, reducing drag with vortex generators, fairings, and wheel covers is a highly effective way to improve fuel efficiency and save money, especially for trucks and freight trains. These devices streamline vehicles, prevent air stagnation, and reduce wake formation, all of which contribute to lower fuel consumption.

Maintain proper tire pressure
Maintaining the correct tyre pressure is essential for optimising fuel efficiency and saving energy. Underinflated tyres can significantly impact fuel economy and lead to other issues, such as diminished tread life and tyre failure. For every 10 psi a tyre is deflated under the recommended settings, vehicles will lose 1% of their fuel economy. In some cases, under-inflation can decrease fuel efficiency by up to 3%.
Tires naturally lose 1 pound per square inch (PSI) of pressure per month, and temperature changes can also cause pressure fluctuations. For instance, a drop in temperature of 10°F can cause a loss of 2 PSI. Therefore, it is crucial to regularly check tyre pressure and adjust it according to the manufacturer's recommendations. The proper tyre pressure for a vehicle is typically found on a sticker in the driver's side door jamb or glove box and in the owner's manual.
By maintaining the correct tyre pressure, you can improve fuel efficiency, enhance tyre durability, and save money. It is a simple and effective way to ensure you are getting the best performance and longevity from your tyres.
Additionally, other maintenance practices, such as keeping the engine tuned and using the recommended grade of motor oil, can also contribute to optimising fuel efficiency.

Use synthetic oil for improved fuel economy
Diesel engines are widely considered to be more fuel-efficient than their petrol counterparts. However, there are still a number of ways to improve the fuel economy of a diesel engine. One of the most effective methods is to use synthetic oil.
Synthetic motor oil is a manufactured product, as opposed to conventional oil, which is a natural product derived from crude oil. Synthetic oil has a number of advantages over conventional oil. Firstly, it has a lower viscosity, meaning it can flow more easily through the engine. This reduced resistance to moving engine parts increases fuel economy.
Secondly, synthetic oil improves cold-flow performance. Conventional oils contain waxes, which cause the oil to thicken when the vehicle is not in use. Synthetic oils, on the other hand, do not contain waxes and so do not thicken as much. This means that less effort is required to circulate the oil when the vehicle is started, improving fuel economy.
In addition, synthetic oils can contain additives such as molybdenum disulphide (MoS2), which can reduce friction by up to 65%. Choosing a synthetic oil with a 'moly' additive can improve fuel economy by 3 to 15%.
While the use of synthetic oil can improve fuel economy, it is important to consider other factors that can impact fuel efficiency. For example, aggressive driving behaviours such as accelerating too quickly or driving at inconsistent speeds can lower fuel mileage. Installing a monitor to track miles per gallon can help to improve these behaviours.
Overall, switching to synthetic oil can be an effective way to improve the fuel economy of a diesel engine, but it is just one of many factors that can impact fuel efficiency.

Diesel as a temporary home heating oil alternative
Diesel fuel can be used as an alternative to heating oil in home heating tanks. However, it is not as simple as filling up your tank and has some drawbacks. Firstly, diesel is taxed differently and tends to be more expensive than heating oil. Secondly, diesel burns hotter than traditional heating oil, which can cause lasting damage to your heating system if used for extended periods. Therefore, diesel should only be used as a temporary solution until you can switch back to heating oil.
When to Use Diesel as an Alternative
You may consider using diesel as an alternative fuel source for your home heating tank if you are experiencing delays in your heating oil delivery due to unpredictable weather storms, road conditions, or other factors. It is important to note that diesel should only be used as a temporary solution, as it is more expensive and can cause damage to your heating system if used for prolonged periods.
How to Use Diesel in Your Heating Tank
If you decide to use diesel as a temporary alternative, follow these steps:
- Turn off your heating tank: Use the thermostat control to ensure your tank is fully off.
- Add diesel fuel: Add up to 10 gallons of diesel fuel to your tank. It is safe to mix leftover heating oil with diesel, and it is better to have some residual heating oil as it indicates that you didn't run the tank completely dry.
- Reset the burner: Let any sediment settle at the tank's base and reset the burner to start it.
- Bleed the lines (if necessary): In some cases, you may need to bleed the lines to release trapped air in the system. This can be a messy and involved process, so consider seeking professional assistance.
- Turn the tank back on: Once you have added the diesel and reset the burner, you can restart your heating system.
Storing and Disposing of Diesel
Diesel fuel can be safely stored for up to six months before it degrades. It should be kept in properly coloured containers—typically yellow gas cans—and labelled appropriately. If you have any unused diesel after using it in your heating oil tank, you may need to contact your local municipality or hazardous waste collection centre for proper disposal.
