fuel prices are absurdly high at the moment. Gasoline is already a burden, but it gets even tougher if you’re behind the wheel of a diesel truck. It’s so severe that Texas has declared a state of emergency, permitting certain drivers to use red-dyed farm diesel on public roads. However, there’s another, less-publicized option that some people are exploring: Black diesel.
This is mainly slang for waste motor oil, though it also refers to used hydraulic oil and automatic transmission fluid. Naturally, individuals have been creating their own fuel from used lubricants since long before diesel climbed over $6 a gallon on average. The procedure resembles that of using waste vegetable oil but requires significantly more cleaning, is unsuitable for recent trucks, and, notably, since it’s untaxed, it’s illegal for road use.
Anyone with adequate space and time can transform waste motor oil into fuel for diesel engines, but there are pitfalls. Several companies provide the essential equipment to process this at home. PA Biodiesel Supply offers the Ultimate Force centrifuge setup, claiming it can eliminate particles at a sub-micron level. This is achieved by spinning the oil at forces exceeding 1,600g, in conjunction with a heater and P-trap system that extracts water from the fuel. Meanwhile, estimates suggest a gallon of black diesel can cost between 10 and 20 cents—a mere fraction of the price of regular diesel.
For those considering this as a route to fund a new Chevrolet outfitted with the 8.3-liter Duramax, reconsider. Waste motor oil can ignite in compression-ignition engines, yet the combustion is nowhere near as clean as the ultra-low sulfur fuel available at the pump. All the non-combustible substances in the oil—ash from calcium, zinc, phosphorus, and magnesium—lead to heightened soot production, quickly clogging a diesel particulate filter. Given how finicky those systems are with cleaner, standard diesel, you would be inviting complications by using it in any vehicle with modern emissions equipment.
That’s the reason PA Biodiesel Supply only recommends using it in diesel engines manufactured before 2005. Ideally, you want models older than that—think along the lines of a 12-valve Cummins or an International 7.3-liter IDI. Many individuals also utilize black diesel in their tractors and heavy machinery, but that’s beyond the present discussion. And did I mention that this isn’t legal for road use?
How to Clean Waste Oil for Black Diesel – WMO – Alternative Diesel – Fuel Prepping – Part 3
Though the expense is a compelling reason to utilize waste motor oil in your diesel equipment, there are numerous drawbacks. You could risk damaging injectors and fuel filters if not adequately refined, and while black diesel can adequately lubricate fuel pumps, it can also introduce harmful contaminants. Additionally, it burns less cleanly than pump diesel, resulting in more deposits from the exhaust. Ultimately, if you’re caught using it, you’ll likely face a hefty fine, as the government typically disapproves of vehicles being on the roads with untaxed fuel.
This blog provides a relatively surface-level exploration of black diesel. It is not exhaustive. However, I did reach out to several individuals in the past who utilize black diesel, and they mostly advised me to keep my distance. It seems that those who engage in this practice prefer to remain private, and there’s a history of the government targeting diesel truck operators who stretch or violate the rules.
**Assessing the Viability of Utilizing Waste Motor Oil in Trucks During Increasing Diesel Prices**
As diesel costs keep rising, the quest for alternative fuels has become increasingly critical for fleet managers and truck operators. One possible remedy gaining traction is the utilization of waste motor oil (WMO) as a fuel source. This article assesses the feasibility of employing waste motor oil in trucks, considering economic, ecological, and technical factors.
### Grasping Waste Motor Oil
Waste motor oil is a byproduct of the lubrication process in internal combustion engines. It comprises a mixture of hydrocarbons, additives, and impurities, rendering it unfit for direct application in vehicles without adequate processing. Nonetheless, when treated properly, WMO can act as an alternative fuel.
### Economic Factors
1. **Cost Efficiency**: With diesel prices fluctuating and frequently hitting all-time highs, using WMO can deliver considerable cost savings. Waste motor oil is usually obtainable at a lower price than fresh diesel, particularly if procured from nearby auto repair shops or recycling facilities.
2. **Accessibility**: The availability of waste motor oil may differ by location. In regions with high concentrations of automotive services, WMO can be more readily available. However, logistical and transportation costs must be factored in when sourcing WMO.
3. **Refining Costs**: To utilize WMO as fuel, it typically necessitates filtration and possibly additional refinement to eliminate impurities. The expenses linked with processing waste oil can diminish some of the savings from its use as fuel.
### Environmental Considerations
1. **Waste Mitigation**: Using waste motor oil aids in lessening the environmental impact of disposing of used oil, which can degrade soil and water if mishandled. Converting WMO into fuel contributes to a circular economy.
2. **Emissions**: While burning waste motor oil may release fewer greenhouse gases compared to conventional diesel, it can also emit harmful pollutants if not combusted efficiently. Advanced filtration and burning technologies are crucial to minimizing emissions and ensuring adherence to environmental regulations.
3. **Sustainability**: The use of WMO aligns with sustainability objectives by fostering the recycling of discarded materials. However, it’s vital to evaluate the total lifecycle emissions and environmental effects compared to standard fuels.
### Technical Aspects
1. **Engine Suitability**: Not every diesel engine is suited for waste motor oil. Modifications might be necessary to accommodate the varying characteristics of WMO, such as its viscosity and combustion properties. Fleet operators must assess whether their existing engines can manage WMO without sacrificing performance or reliability.
2. **Fuel Integrity**: The quality of waste motor oil can differ greatly based on its source and usage background. Consistent fuel quality is essential for optimal engine operation. Implementing stringent quality control measures during the processing of WMO is critical to ensure dependability.
3. **Regulatory Compliance**: Utilizing waste motor oil as fuel may be subject to various regulations and standards. Fleet operators need to be aware of local laws regarding the use of alternative fuels and ensure compliance to avert legal complications.
### Conclusion
The practicality of using waste motor oil in trucks amid soaring diesel prices presents both opportunities and challenges. While the prospect of cost savings and environmental advantages is significant, careful attention must be given to processing, engine compatibility, and regulatory adherence. As technology evolves and more efficient processing techniques are created, WMO could become a feasible alternative fuel option for the trucking sector, promoting a more sustainable future.
