Fall Weather Arrives in North Dakota

This past week in North Dakota, the weather has started to cool into the 30s as we go into winter. The week started slowly and darkly as a cloudy overcast hung low for several days. It seemed certain it would snow any minute. On the Mountain & Central timeline border, it remained dark all the way up to 8:30 am. Fall weather has arrived.

International Shipments to Australia & New Zealand

Beginning the week, packages were made and shipped to customers worldwide. Notably, two waste oil centrifuge packages, the Ultimate Force Fuel System went to Craig in Australia and Michael in New Zealand. It’s not just the US—diesel prices are expensive everywhere around the globe. More people are turning to waste vegetable oil (WVO) and waste oil filtration as diesel fuel alternatives. Out of curiosity, I checked diesel prices in Australia and discovered that diesel is hovering at $4.57 a gallon.

Comparatively, On-Highway diesel prices in the U.S are currently at a national average of $3.72 per gallon according to the U.S Energy Information Administration. While lower than it was a couple of years ago, when diesel was at an all-time high of $5.75 a gallon in June of 2022, diesel is still at historically high prices. The image below, which I found on the U.S. EIA page, breaks down where the money we spend on fuel goes.

Discovered an Email Info-Series I Wrote Over the Summer

On Tuesday, while doing computer work I discovered a 30-email newsletter that I put together in May and never published. It is an info-letter email series that I poured some 20 hours of time into writing. Everything from finding waste oil, to the different types of oil to collect, gear pumps, rotary pumps, and of course, cleaning waste oil with centrifuges. Another 70 or so emails are planned, each one on a different topic. The one I look forward to writing the most is “Series vs Parallel Centrifuge Setups” and discussing the effectiveness of single and dual passes. Over the years, quite a bit has been learned from personal experience running waste oil fuel and learning from others. Eventually, I’ll take time to write the other 70 emails and finish the Black Diesel email series. The emails are quite informative, covering WVO and WMO filtration to centrifuge maintenance. You can sign up below to get them sent to you.

Inventory Management Software & Better Stock Keeping

Another project that my time has been devoted to this past week, on the operations side, is inventory management. In the past, I’ve always hand-counted everything about once a quarter. It is time consuming. This year I failed to do that—moving and setting up the new workshop, I’ve kept myself busy and didn’t want to do it. As a result, the Ultimate Force Pump Kit for our centrifugal systems are out of stock due to not ordering early enough. To be fair, I ordered another dozen of the N999 Oberdorfer Pump Heads back in July, with delivery promised in October. In October, a delivery was made—but it was just the adapter plates! The manufacturer, Oberdorfer, is moving locations and pump production has been shut down for the past 6 months. They are not expected to fulfill orders for another 6 months, around April or May of 2026. Back to inventory management…

The reason for taking inventory seriously is that centrifuges and waste oil filtration kits are always in stock and ready to ship out the same day. No need to build the kit on the spot and hope I have everything that is needed. Secondly, once the centrifuges already built, all the materials to build more centrifuges and kits are available without needing to order anything. Everything is ready to go, and when inventory is low, it’ll send me an automatic email reminding me to purchase more of that part, so I can build your centrifuge system.

I’m excited to finish setting up the inventory software this week (best part is that it is free!), and soon you’ll see kits and products on the shelves ready to go in the workshop! Finally getting around to tracking the goods I have in stock will allow me to better help customers like you, faster, and stay in business for many years to come.

This is the update from the past week, and what I’ve been up to in the business.

This past week, I made some progress with the engine centrifuge (COF) kits, which you may have seen on YouTube. If you’re not familiar, the COF engine kit purifies the engine oil while the engine is running. The rotor spins at 6,000 rpm, creating centrifugal force and capturing sludge and soot just like a waste oil fuel centrifuge for waste vegetable oil (WVO) or waste motor oil (WMO), aka Black Diesel. These kits will install will extend the life of the oil and engine by removing wear particles that damage the bearings, bore, and pistons. Debris as small as 0.1mm (1/50th the size of a red blood cell) is captured in the rotor and can be cleaned out at the next oil change. 

Sending An Oil Tube To Blackstone Oil Lab For Analysis

The first test vehicle, my 1995 F250 with a 351W engine just crossed 8,000 miles since the last oil change over the summer. Originally, plans were to test the oil at 5,000 miles, but life is busy and it quickly passed by with the number of miles I drive monthly. This past Monday, an oil sample was collected from the engine, which you can watch in this video. In addition to the sample, a previous oil change with 12,000 to 15,000 miles was sent in out of curiosity, though not a base or comparison. This is due to the high miles on the motor oil and not being equipped with a centrifuge system at the time. Results should be received in a few short weeks, and tell us the effectiveness of the centrifuge engine system. 

Aside from the lab study, later this week, the rotor will be removed and opened as a leak on the mounting plate is resealed. While the rotor is removed, it’ll be opened so we can examine how much debris it has captured. Typically, these rotors only need to be cleaned every 25,000 to 30,000 miles on a diesel engine. So, with only 8,000 miles and the clean gas-burning 351W engine, I am not expecting to see very much debris or sludge. The leak is caused by the temperature dropping as we go into winter in North Dakota. At the time of installation, I should have used RTV as a sealant but I did not. My mistake, I was too excited during the installation and skipped that step. The leak is not terrible, just a light weep on startup up which leaves a residue on the inner plastic fender it is mounted on. 

New Website Coming Soon For Centrifuge Oil Filtration
Specifically Made for Engine Centrifuge Kits & Information

A new website specific to the COF engine kits will soon be clickable and ready to look at! The website, COFkits.com is under construction and is where you will soon be able to sign up on the waiting list. (Chance to win a FREE COF Engine Kit!!!) The brand “Centrifuge Oil Filtration” (COF for short) will be a sister company to PA Biodiesel Supply. The COF kit, while a centrifuge product, is not related to biodiesel or waste oil fuel, and thus best situated as its own unique company and product. At this time, I do not yet have a release date for the kit, but my hope is that it will be available by spring of next year. Research and testing still need to be done. Once I am done personally testing the COF system on my pickup truck, testers will be selected to install the COF kit on their own engines and report their findings. At this moment, testers are not being selected, but you will soon be able to apply! 

This is the sum of all the updates on the COF project from this past week. In a few days, the oil centrifuge will be removed from my truck to repair the leak and review the rotor, so stay tuned! If you find this project interesting and want to share it with your friends and family, click here so they can learn about it for themselves.

Perfect Your Waste Oil Centrifuge Flow Rate for Cleaner Fuel

When cleaning waste oil with a centrifuge, flow rate is one of the most important things to get right. Many people think faster is better, but that’s not true when it comes to producing clean fuel. Understanding flow rate will help you get the best results from your Ultimate Force Centrifuge.

Why Flow Rate Really Matters

Think of your centrifuge like a washing machine for oil. The longer the dirty oil stays inside the spinning bowl, the cleaner it becomes. The powerful centrifugal force has more time to pull out dirt, water, and other contaminants without fighting against oil trying to escape too quickly.

For making vehicle fuel, we recommend running at 5 gallons per hour (GPH). This slower speed gives the centrifuge time to do its job properly. If you’re cleaning oil for other uses like oil burners, you can speed it up to 10 GPH and still get good results. The Ultimate Force Centrifuge does have a flow rate rated up to 30 GPH, but you sacrifice oil purity and will remove fewer contaminants.

How Flow Rate Actually Works

Inside your centrifuge bowl, two forces are working against each other. The spinning creates a strong centrifugal force that pushes dirt and contaminants to the bowl walls. At the same time, the flowing oil creates an opposing force trying to escape. When you rush the flow, you make it harder for the centrifugal force to do its job effectively.

The Ultimate Force Centrifuge creates 1,657 times the force of gravity (1,657 G-Force). At a 5 GPH flow rate, your oil experiences this powerful force for a full 6 minutes. That’s plenty of time to settle out even the smallest particles.

Measuring Your Flow Rate is Simple

You don’t need fancy equipment to check your flow rate. All you need is a quart jar and a timer. Here’s the easy way to figure it out:

First, multiply your target flow rate by 4 (since there are 4 quarts in a gallon). Then divide 60 minutes by that number.

For example, if you want 5 GPH:

• 5 gallons × 4 quarts = 20 quarts per hour
• 60 minutes ÷ 20 quarts = 3 minutes to fill one quart

Here’s a quick reference for different flow rates:

• 2.5 GPH = 6 minutes per quart
• 5 GPH = 3 minutes per quart
• 7.5 GPH = 2 minutes per quart
• 10 GPH = 1.5 minutes per quart
• 15 GPH = 1 minute per quart

Why Heating Makes a Difference

The height and size of your oil container affects flow rate more than most people realize. A full 55-gallon drum creates about 1.2 psi of pressure at the bottom. Larger 275 or 330-gallon totes can create 2.5 to 3 psi of pressure.

As your container empties, this pressure drops and your flow rate slows down. Each foot of height above your centrifuge adds roughly 0.38 psi of pressure. A drum placed 5 to 8 feet above your centrifuge will maintain a steadier flow rate.

Using a larger input hose between 5/8″ and 1″ diameter also helps by reducing friction. This is especially helpful if your oil cools as it moves through longer feed lines.

Setting Up Your Flow Control

To control your flow rate properly, use two valves. Set up a gate valve to adjust the flow rate and a ball valve to turn the flow on and off. This way, you don’t have to readjust your flow rate every time you start the centrifuge. In the picture below, you can see that we used two valves.

Pre-heating your oil before it enters the centrifuge will give you cleaner results and help it flow better, especially in cold weather. This simple step can make a big difference in how well your system works and the purity of your oil. We always recommend an inline heater when using a centrifuge.

The Slower the Oil, the Cleaner It Will Be

Remember this simple rule: slower flow rate equals cleaner oil. Taking the time to set up your centrifuge at the right flow rate will pay off with cleaner fuel. Your engines will run smoother, and you’ll save thousands of dollars on fuel costs.

Whether you’re processing a few gallons or hundreds, patience with the flow rate is your key to success. The Ultimate Force Centrifuge is designed to give you the best results when you follow these guidelines.

Introduction

If you’re exploring alternative fuels like black diesel, waste motor oil (WMO), waste vegetable oil (WVO),  or biodiesel, you know that cleaning waste oil is a major step before using it in a diesel engine. The two most common ways to filter waste oil are using a waste oil centrifuge or filters. But which one works best? A research study on waste motor oil as fuel has some surprising findings about how well each method works—and why filters might not be as good as you think.

The Problem with Dirty Waste Oil Filters

When oil is used in an engine, it picks up metal shavings, dirt, soot, and water. If you burn it in a diesel engine without proper cleaning, these contaminants can cause serious damage. 

“The particles entrained in the high-pressure fuel essentially act as a sandblasting media as it passes through the pumps and injectors,” the study explains. “The most damaging particle sizes are in the 2-10 micron range. They are also the most difficult to filter out.”

To prevent engine damage, WMO needs to be filtered down to at least 1 micron, which is the standard size for diesel fuel filters in many modern engines, like the Cummins QSK38. But how do you remove these tiny particles?

How Cartridge Filters Work (And Their Hidden Problems)

Many people use cartridge filters (like the ones in diesel trucks) or sock filters to clean their waste oil. These filters are rated at different micron levels, such as 10 microns, 5 microns, and 2 microns. The idea is that oil is pushed through the filter, trapping dirt and metal inside. But there’s a big problem—filters can actually add contamination back into the oil!

The study found that some filters released more debris than they removed. “In every single metal species, the cartridge filter sample actually added more contaminants to the sample or remained the same instead of removing anything,” the research states. This happened because the filters were already partially clogged from previous use, causing them to release trapped particles back into the oil. Oil filters have to be changed frequently or you risk contaminating batches with more debris than you started with. 

Filters also have another issue: they can’t remove water from waste oil. If you burn WMO with water in it, you risk damaging your injectors and creating steam in your fuel system.

How Centrifuges Work

A waste oil centrifuge operates using centrifugal force to separate contaminants from the oil. Instead of pushing oil through a mesh or paper filter, the centrifuge spins the oil at high speeds. Heavier contaminants like metal shavings, dirt, and sludge are forced to the outer edge, while the cleaner oil remains in the center and is drained off. This method ensures that even the smallest impurities, which often slip through cartridge filters, are removed effectively. The two styles of centrifuges are bowl style and pressure driven, which is explained below.

“A bowl-type centrifuge is a bowl that spins at … (high) [r]pm. The centripetal force due to centrifugal motion causes the WMO to be pushed up against the walls of the bowl. Heavier particles will stay against the wall while the good oil rises to the top towards the hole in the middle then will drop out into a container below.”​

“A spinner-type centrifuge is powered by the force of the pumped oil itself. Pressurized oil is pumped through the rotor and the velocity of exiting oil through jet nozzles powers the centrifuge.”​

Centrifuges are capable of filtering waste oil down to sub-micron levels. The study found that centrifuges consistently removed contaminants without reintroducing them into the oil, unlike cartridge filters. This makes them highly efficient at purifying waste oil for alternative fuel use.

Why Centrifuges Clean Waste Oil Better

One major advantage of using a centrifuge is that it does not clog like traditional filters. Cartridge filters lose efficiency as they accumulate debris, requiring frequent replacements and maintenance. A centrifuge, on the other hand, can process large volumes of oil without losing effectiveness.

“The process may need to be stopped periodically to disassemble the bowl for cleaning. This involves scraping sludge from the bowl. This sludge will probably be surprising to the user as to how much contamination could have been missed by other methods previously mentioned.”​

Another significant benefit is water removal. Water in fuel can cause injector damage, reduce combustion efficiency, and lead to engine failure. Cartridge filters are ineffective at removing water from oil, but centrifuges successfully extract moisture, ensuring a cleaner and more engine-friendly fuel.

“A spinner-type centrifuge is capable of filtering down to one tenth of a micron but is not intended to remove water or antifreeze. However, the centrifuge did have a slight effect on water removal, reducing contamination by up to 23% in one test.”​

From a cost perspective, centrifuges are a long-term investment. Depending on fuel costs in your area, producing as little as 350 gallons of black diesel is a 100% ROI. While they may require a higher initial cost, they eliminate the need for constantly replacing filters. The research study found that cartridge filters not only became saturated quickly but sometimes worsened contamination. “There were eight species showing negative removal rates, meaning that material was added into the oil by the filtering process.” In contrast, centrifuges provide reliable purification without the cost of filter replacements.

Oil Filtration Made Simple

Below, you’ll discover commonly used definitions and terms within the oil burner and biodiesel community. Familiarizing yourself with these terms is important when processing and producing waste oil. The provided definitions cover various aspects of the biodiesel process, including acronyms and chemicals utilized in biodiesel production. In addition, it covers terms and acronyms used when processing Waste Oils or Black Diesel. 

ASTM: The organization that sets international standards for a variety of materials. The specification for biodiesel is ASTM D6751. Renewable diesel falls under ASTM D975, the diesel specification.

Autoignition: Autoignition is the spontaneous ignition of a substance, such as biodiesel, without an external ignition source. Understanding the autoignition temperature is crucial for safe handling and storage.

B20: B20 refers to a blend of 20% biodiesel and 80% diesel fuel. It is a common biodiesel blend used in various diesel engines.

B5, B10, B20: A fuel that is a blend of biodiesel and petroleum diesel is commonly abbreviated to a “B” and then the percentage of biodiesel in that fuel. B20, for example, is 20 percent biodiesel and 80 percent petroleum.

Biodiesel: A cleaner-burning alternative to petroleum diesel that is made from renewable resources that would otherwise have no further use, including recycled cooking oil, waste animal fats, and vegetable oils.

Biodiesel: Biodiesel is a renewable fuel derived from organic materials such as waste vegetable oil or animal fats through a process called transesterification.

Brake Fluid: Brake fluid, specifically Dot 3 fluid, is cautioned against in backyard biodiesel production due to its harmful nature. It should not be used as a feedstock.

BTUs: BTUs (British Thermal Units) measure the energy content of fuels. Understanding the BTU value helps assess the efficiency of a fuel source.

Cetane number: A measure of a fuel’s combustion speed and a common indicator of fuel quality. The higher the Cetane number, the shorter the ignition time. Biodiesel and renewable diesel have a higher Cetane number than petroleum diesel.

Cloud Point: The temperature at which wax crystals cause fuel to appear cloudy. The higher the Cloud Point, the sooner the fuel starts to gel. It is one way to measure cold weather performance.

Distillation: The process of purifying a liquid using evaporation and condensation. Distillation is one of the ways biodiesel is purified, and distilled biodiesel has several benefits, including superior cold-weather performance.

Emulsification: Emulsification is the process of mixing two immiscible liquids, like water and oil. In biodiesel production, avoiding emulsification is crucial to prevent water contamination

Emulsified Oil: Emulsified oil results from the mixing of oil and water, which can complicate the biodiesel production process. Proper separation is necessary for quality fuel.

Ethanol: Ethanol is an alcohol that can be used in biodiesel production. It reacts with triglycerides in the transesterification process.

Ethylene Glycol: Ethylene glycol is a substance to be avoided in biodiesel production as it can be harmful. It is commonly found in antifreeze.

Fatty acid methyl esters: The chemical name for biodiesel, often abbreviated as FAME. A FAME molecule is comprised of a fatty acid and an alcohol.

Feedstock: The raw material used to create fuel. For biodiesel and renewable diesel, these are renewable resources such as recycled cooking oil, vegetable oils, and waste animal fats.

Flash Point: The flash point is the lowest temperature at which a substance vaporizes to form an ignitable mixture. It’s a safety consideration in handling biodiesel.

FPHE: FPHE stands for flat plate heat exchanger, a device used to transfer heat efficiently in biodiesel production processes.

Glycerin: Glycerin, or glycerol, is a byproduct of the transesterification process in biodiesel production. Proper disposal or utilization is essential.

Gravity Fed Centrifuge: A gravity-fed centrifuge is a direct-drive centrifuge with the motor directly coupled to the rotor. It facilitates the separation of impurities from biodiesel.

Greenhouse gases: Gases, such as carbon dioxide, that trap heat in the atmosphere, contributing to global warming.

Hydrocarbons: An organic compound containing carbon and hydrogen. In the presence of nitrogen oxides (NOx) and sunlight, unburned hydrocarbons create ground-level ozone, which harms lungs and creates urban smog.

Lubricity The ability of a lubricant to reduce friction and prevent wear in an engine. Ultra-low sulfur diesel has very little lubricity, whereas biodiesel has great lubricating characteristics.

Methanol: Methanol is a key component in the transesterification process of biodiesel production. It reacts with triglycerides to form biodiesel.

Neat biodiesel: Biodiesel that has not been blended with another fuel. It is 100 percent biodiesel and is also called B100.

Particulate matter: Particulates — including solids and liquid droplets— from exhaust systems harm the climate and human health. Fine particles can penetrate deep into a person’s lungs and even enter the bloodstream.

pH Testing: pH testing involves measuring the acidity or alkalinity of biodiesel. It ensures the fuel falls within acceptable ranges for engine compatibility.

Pressure Centrifuge: A pressure centrifuge is a centrifuge that spins from oil pressure escaping the rotor, aiding in the separation of impurities from biodiesel.

Regular Unleaded Gasoline (RUG): RUG refers to regular unleaded gasoline, a type of fuel that should be avoided in the production of biodiesel due to its different chemical composition.

Renewable diesel: A renewable fuel that is chemically similar to petroleum diesel but with much lower emissions. It is made from the same feedstocks as biodiesel but has a different production process and meets a different specification.

Settling: Settling involves allowing oil to sit so that water and oil separate, and debris drops out of the oil. It is a crucial step in biodiesel production.

SVO: SVO stands for Straight Vegetable Oil, which can be used as a feedstock in biodiesel production.

Transesterification: A chemical process in which feedstock is reacted with an alcohol (typically methanol) to make biodiesel.

ULSD: ULSD stands for ultra low sulfur diesel, a type of diesel fuel with reduced sulfur content.

W80: W80 is a fuel blend consisting of 80% waste oil and 20% regular unleaded gasoline.

W90: W90 is a fuel blend consisting of 90% waste oil and 10% regular unleaded gasoline.

Wash Process: The wash process is a step in biodiesel production that involves removing impurities, catalyst residues, and glycerol from the biodiesel.

Waste Motor Oil (WMO): WMO is used lubricating oil that can be recycled and potentially used in the production of black diesel.

Waste Vegetable Oil (WVO): WVO is a discarded cooking oil, often used as a feedstock in biodiesel production.

WATF: WATF stands for Waste Automatic Transmission Fluid, which can be considered as a feedstock in biodiesel production. WATF is one of the best oil sources that can be used as a fuel because of its viscosity and detergent properties.

1. Bowl Removal

Using an 8 mm Allen wrench, secure the bowl and loosen the nut by turning it counterclockwise. Gently pull the bowl out of the housing and place it in a container to collect any residual oil.

2. Bowl Mount Removal

Utilize a gear puller obtained from an auto parts store. Attach the three hooks to the bottom of the bowl mount. Hand-tighten the gear puller, then use a wrench for further tightening to safely remove the mount from the motor shaft. Ensure the force is applied to the motor shaft, not the housing, allowing the mount to slide off smoothly.

3. Motor Removal

Using a 4mm Allen wrench, remove the three legs of the Ultimate Force Centrifuge, placing the motor base on the ground. This will aid in removing the motor from the unit. Using a 3/16 Allen head screwdriver, remove the 4 bolts securing the motor. Set them aside in a safe location, not damaging the sealed washers if reusing. Remove the housing by lifting up from the motor. Flip the housing upside down and, with a mallet and socket, gently tap out the old seal.

4. Install New SKF Seal

Lightly coat the Ultimate Force Centrifuge Housing with silicone or grease to facilitate seal installation. Verify the coil spring inside the SKF seal is properly seated. Use a socket or pipe fitting of similar size to tap the motor shaft seal into place carefully. Avoid overdriving the seal to prevent compromise or damage.

5. Install The Motor

Place the motor on a stable surface, lubricate the motor shaft with grease, and slide the housing onto the motor shaft, ensuring not to damage the rubber seal. Use the sealed washers from our reseal kit on the 4 housing bolts and securely tighten them into the motor.

6. Install V-Seal and Apply Anti-Seize

Slide the V-seal down the motor shaft, pushing it firmly into the motor shaft seal with the V portion facing down to prevent leaks. Apply a thin layer of antifreeze onto the motor shaft for easier future installation and removal of the bowl mount.

7. Install Bowl Mount

Heat the bowl mount in boiling water for 5 to 10 minutes. Using pliers, carefully pick up the bowl mount and quickly slide it onto the shaft, avoiding burns or drops. Ensure the bowl mount is fully seated by the groove, catching the motor shaft lip. Allow the bowl mount to cool for 5 minutes; if not fully seated, repeat the process.

8. Attach Bowl to oil centrifuge unit

Place the bowl into the housing and onto the motor shaft. Hold the bowl steady with an 8 mm Allen wrench and turn clockwise to tighten the nut.
