Filtering oil
Firstly, it is important to understand the role of filtering in the context of making black diesel fuel. The goal is to remove contaminants and impurities from the oil before it is used as fuel. This includes debris, water, and other substances that may interfere with the proper functioning of the fuel system.
The type of filter used is an important consideration. Common household items such as denim or old clothing are not suitable for effective oil filtration. Engine oil filters are typically around 20 microns, so using a finer filter, such as a 1-micron bag, is recommended to achieve a higher level of filtration. It is also important to support the filter bag to prevent it from stretching under the weight of the oil, which can compromise its effectiveness.
A multi-stage filtration process is often employed to achieve a more thorough filtration. This involves using filters of varying micron sizes, from larger to smaller, such as 75-micron, 5-micron, and finally 1-micron bags. This prevents the filters from clogging too quickly and ensures that the oil is progressively refined.
When filtering, it is important to consider the viscosity of the oil. Cold oil can be difficult to blend, so it is recommended to heat the oil to around 100°F to facilitate blending and filtration. Blending should be done vigorously, and the oil should be blended in stages as it reaches different levels in the storage tank. The thickness of the oil will depend on factors such as seasonal temperature and the specific requirements of your engine's fuel system.
Finally, it is crucial to pay attention to safety when filtering oil. Always wear protective gear, including gloves, goggles, and respirators, to shield yourself from harmful substances and fumes. Ensure that the work area is well-ventilated and free from open flames during the blending and filtration process.

Blending oil
When blending oils, it is essential to consider the temperature. Cold oil can be challenging to blend, so it is recommended to heat the oil to around 100°F before blending. Blending should be done vigorously and in stages, with each blend depending on several factors. These factors include seasonal temperature, engine temperature, and vehicle-specific requirements. For example, older engines and hotter climates can handle thicker blends, while cooler seasons may require more thinning.
The type of thinning fuel used is also important. Only oil-based thinning agents should be used, such as diesel, petrol, kerosene, light hydraulic oil, terps, and paint thinners. These thinning agents help reduce the viscosity of the waste engine oil, making it suitable for use in diesel engines.
Additionally, filtration is a critical aspect of the blending process. Proper filtration ensures that contaminants and impurities are removed from the waste engine oil. The oil should be filtered multiple times through micron filter bags to achieve the desired level of purity. The size of the micron filter bags can vary, with some sources recommending 1-micron filters or smaller to prevent clogging and ensure effective filtration.
Some people have shared their experiences blending oil to make black diesel fuel. One person shared their blend of 50% waste engine oil and 50% diesel in the summer, while another person used a blend of 70% waste engine oil and 30% diesel in the winter. It is important to note that blending ratios may need to be adjusted based on temperature and engine requirements.

Thinning oil
There are various thinning agents that can be used, but it is important to ensure they are oil-based and compatible with oil. Some common thinning agents include diesel, petrol, kerosene, light hydraulic oil, terps, and paint thinners. Paint thinners, also known as mineral spirits, are petroleum distillates commonly used to thin oil-based paints. They are effective in removing oils, greases, and carbon from metal surfaces. When using paint thinners, it is important to follow safety guidelines as exposure to their vapours can be harmful.
Another important aspect of thinning oil is temperature control. Cold oil can be difficult to blend, so it is recommended to heat the oil to around 100°F to facilitate the blending process. The blending should be done vigorously and in stages, with each stage corresponding to a certain level of oil in the storage tank. Seasonal temperature also plays a role in thinning, with more thinning required in cooler seasons than in warmer ones.
In addition to thinning, filtration is a crucial step in the process of making diesel fuel. It is recommended to filter the oil to a level finer than that of the fuel filter in your vehicle. For example, if your fuel filter is 2 microns, you may want to use a 1-micron bag to filter the oil. This helps prevent blockages and ensures the smooth operation of your engine.
Overall, thinning oil is a critical step in making diesel fuel at home. By using the appropriate thinning agents, controlling temperatures, and employing effective blending and filtration techniques, you can produce diesel fuel that meets your specific requirements.

Distilling oil
To distill oil at home, you will need a setup that includes a still, a condenser, heat sources, collection vessels, and filters. The still is a crucial component as it heats and vaporizes the plant material. The condenser cools the steam, allowing it to condense back into a liquid form and separate the oil from the water. Safety precautions and protective gear are essential when handling hot steam and concentrated oils.
Before beginning the distillation process, carefully select and collect the plant material you will be using. Different plants have unique timelines for optimal harvesting, so it is important to research the specific plant you plan to use. Additionally, the way you handle the plants during harvest can impact the quality and quantity of your essential oils. Most plants should be processed immediately after harvest, but if immediate distillation is not possible, proper drying techniques must be applied to prevent rotting.
The distillation process itself can vary in duration, typically ranging from 1 to 8 hours depending on factors such as the type of oil, equipment used, and quantity of plant material. Steam distillation is widely recognized as a safe and effective method for extracting essential oils at home. It involves heating water to produce steam, which then passes through the plant material, releasing the essential oils.
It is important to note that not all plants can withstand the heat of steam distillation. Alternative methods, such as cold blending, may be considered for temperature-sensitive plants. However, cold oil tends to be difficult to blend, and blending at higher temperatures generally produces better results.

Mixing oil with gasoline
Firstly, it is important to understand the basics of petroleum composition. Petroleum is made up of two types of molecules: straight chains and rings. Ring-type molecules are ideal for gasoline blends as they resist detonation during the engine's compression stroke. Longer chains, on the other hand, are more suitable for diesel fuel as they easily detonate and cause knocking, which is desirable in diesel engines.
When creating your own black diesel fuel, the process involves mixing waste engine oil with lighter oil to thin it down. The ratio of this mixture will depend on the type of engine you are using. For instance, a 50/50 ratio is recommended if you are unsure, but older engines and hotter climates can handle thicker fuel, so you can adjust the ratio accordingly. It is crucial to use oil-based thinning agents that bond with oil, such as diesel, petrol, kerosene, light hydraulic oil, terps, or paint thinners.
The mixing process should be done in stages, blending vigorously at each 20-25% level in the storage tank. Blending is critical to ensure the mixture is homogeneous. The ideal temperature for blending is around 100°F, as cold oil can be difficult to blend. Seasonal temperatures and engine temperatures will also influence the thickness of the oil and, consequently, the blending process.
After mixing, the fuel should be filtered. This can be done using a multi-stage filtration process with filter bags of varying micron sizes to ensure that the fuel is free of impurities.
It is important to note that mixing oil and gasoline in a 4-cycle engine is not advisable, as it can lead to insufficient lubrication and excessive wear on engine parts. Always refer to your engine's instruction manual for specific guidelines and take the necessary precautions to avoid damage.
