How to Run Your Car on Used Salad Oil
by Erica Gies
For financial, political and environmental reasons—including the fact that we may soon reach the peak of oil production, after which fossil fuels will get increasingly expensive—Americans are trying out biodiesel, both in their vehicles and (mainly in the Northeast) for home heating.
Biodiesel emits 78 percent less carbon dioxide (CO2) emissions than petroleum diesel, according to the National Biodiesel Board, but it’s not necessarily squeaky green. According to Kathryn Phillips, manager of Environmental Defense’s California Clean Air for Life campaign, it actually increases nitrous oxide (NOX) emissions, which react with other chemicals to create ground-level ozone, or smog, significantly impacting lung development in children.
However, Phillips adds that the biodiesel industry is working on methods to reduce NOX via an additive or catalyst. NOX emissions result from the catalytic conversion process and therefore aren’t a problem when biodiesel is used for home heating.
Another area of concern is that biodiesel is often made from genetically engineered (GE) soybeans, and is a product of the industrial agriculture system that results in topsoil loss and fertilizer runoff. Actress and biodiesel advocate Daryl Hannah counsels caution about the developing industry, warning, “It may encourage people to use more pesticides and GM crops. We shouldn’t cut off the nose to spite the face.”
Without workarounds, biodiesel faces cold-weather issues since it becomes unusably gelatinous as the temperature approaches freezing. Still, in spite of its challenges, biodiesel is a far greener alternative than petroleum, according to its advocates. “Particulate matter from diesel is a really bad pollutant and a carcinogen,” says Phillips. And in spite of its long-held reputation as being a premium-cost fuel for elite environmentalists, after shortages caused by Hurricanes Katrina and Rita the price of biodiesel became quite competitive with standard fuel oil for Northeastern homeowners with oil burners.
Take Action
If you want to use the alternative fuel to wean yourself off Big Oil, step one is to buy a diesel car or truck, since gasoline vehicles can’t burn biodiesel. (However, Hannah points out that gasoline-powered cars can be converted to run on alcohol/ethanol. She’s put the TransAm from her film Kill Bill up on blocks until she gets a chance to do the conversion.)
There are three basic fuels available to biodiesel drivers: B100 (pure, processed biodiesel from retailers), B20 (a blend of 20 percent biodiesel and 80 percent regular petroleum diesel, also available from retailers), and fryer oil (“recycled” oil from restaurants that is not sold commercially).
B100 and B20 can be put directly into any diesel engine. If drivers are unable to find biodiesel (or if it’s too cold to use the higher blends), they can simply switch to standard petroleum diesel. B20, because it is mostly diesel fuel, can be used virtually year-round.
The best solution for using B100 in the winter is to use a heated filter or a tank heater, both of which plumb the coolant system to heat the fuel to 180 degrees Fahrenheit. Once the engine is warmed, it alone can keep the biodiesel at the proper viscosity. Robert Lewis, technical service specialist at fuel filtration products company Racor, says his company sells these devices for $200 to $400. But, he adds, “You still need a second tank with diesel fuel for the starting and shutting down sequence, because you don’t want the oil to gel inside the filter when it gets cold.”
Lewis says he gets the most calls from customers who want to run their vehicles on straight used vegetable oil, also known as SVO. For people willing to mix petroleum with their biodiesel, engine gizmos aren’t necessary. Instead, you can mix your fuel in different concentrations throughout the year, as biodiesel advocate Charris Ford did when he lived in Telluride, Colorado. He used 50 percent petroleum diesel in the winter and 25 percent in the spring and fall, running 100 percent biodiesel only in the summer.
Blended biodiesel fuels sold commercially can be made from recycled oil, the most environmentally friendly option. Using recycled oil consumes a waste product, which boosts its carbon neutrality. But John DeCicco, a senior fellow at Environmental Defense, points out that virgin biodiesel is not necessarily “carbon neutral” as advertised. That claim comes from the fact that the plants grown to make the fuel absorb CO2 as they grow, offsetting the exhaust produced when burned.
“Did you fertilize that plant?” asks DeCicco. “Did you till the field? Did you truck it somewhere? Where did that energy come from? There’s a lot of bookkeeping that has to be done to figure out whether a specific batch of biodiesel is actually carbon neutral.”
Jorah Roussopoulos, co-owner with his partner Andi Rubalcaba of the first solar-powered biodiesel pump in the country in Ben Lomond, California, understands this implicitly. It’s for that reason he stocks recycled B100 at his store whenever he can get it.
Other biodiesel drivers want the freedom to drive up to a restaurant’s grease pit, filter the used fryer oil, and put it directly in their tanks. Worried about the supply? There is an estimated 4.5 billion gallons of used vegetable oil generated every year, according to passionate advocate (and country singer) Willie Nelson. For that capability, you need a conversion kit. Massachusetts-based Greasecar sells one that includes a special biofuel tank, filters, heat exchangers and plumbing. A turn-key conversion costs $1,500, but if you’re mechanically inclined, you can install it yourself for $795. Missouri-based Greasel also makes a kit.
Before you run out and buy that brand-new, diesel-powered VW Passat, you might want to consider warranty issues. Volkswagen currently only approves the use of B5, according to spokesperson Patrick Hespen. (Further, VW diesels are not currently sold in some states because they fail to comply with strict California emission regulations.) General Motors offers only one diesel vehicle in North America, the Duramax 6.6 liter V-8 turbo, and it too only approves the use of B5.
There are only 200 or so biodiesel stations in the country, according to Greg Pahl, author of Biodiesel: Growing a New Energy Economy. So enthusiasts in some communities are forming cooperatives to get their fixes. Still, the stuff isn’t cheap, often selling for a dollar or so more than unleaded gas. Roussopoulos sells his B100 for $3.65 a gallon, a price at which he says he’s losing money. “The whole idea right now is to raise awareness,” he says. “Somebody has to do it.”
Heating Oil Too
Some homeowners in the Northeast are getting biodiesel blended into their home furnace mixes whether they asked for it or not. Oil companies in Connecticut, for instance, are assuring customers that this exotic new fuel won’t damage their boilers. Devine Brothers, a veteran home heating specialist in Norwalk, Connecticut, has taken out billboards, trumpeting the virtues of blended biodiesel, which in a two-year test administered in the Warwick, Rhode Island school system performed better than conventional heating oil in both burner efficiency and emissions.
Customers of Santa Fuel, also Connecticut based, are getting a five percent biodiesel blend at no extra charge. “This is something we believe in as a company,” says general manager Peter Russell. “It’s a renewable product that is good for the environment. Five percent is not a lot, but it’s a great start.”
The Central Connecticut Biodiesel Consumer Cooperative, helmed by mechanical engineer Karl W. Radune, is working to convince consumers that B100 won’t harm their furnaces. Some experts are concerned that B100 will erode the rubber seals in furnace pumps, but Radune says a few dollars worth of Teflon replacements will sidestep the problem.
Environmental concerns, coupled with high fuel-oil prices, are making biodiesel more popular for various uses. Biodiesel production is up markedly across the country, from 18 million gallons in 2002 to 30 million gallons in 2004, according to the National Biodiesel Board.
Soybean oil is the most popular for biodiesel, but canola works well and people are experimenting with other sources. France has distilled excess wine into fuel. A professor at the University of Illinois planted a field trial of a grass called Miscanthus that grows 14 feet tall and has been bred to be sterile, so it won’t go haywire as an invasive species. Roussopoulos mentions certain algaes that produce as much as 50 percent oil and can grow in brackish sewage ponds.
Many options are not yet in play that could further reduce our carbon footprint, but biodiesel pioneers aren’t waiting. They’re driving down that black ribbon of highway, French fry fumes floating in their wake.

More propaganda.
Crude oil is used to produce fertilizers and pesticide. Where do they get more salad from? Obviously from fertilizers or pesticides which means we go back to using crude oil.

This catalyst will most likely be platinum. The same catalyst used for hydrogen fuel cells. Think we have enough platinum? Think we can import platinum easily enough? Think again. Platinum reserves are located in southern Africa and Russia. Africa with lots of civil wars just like in Nigeria. Russia being a rival to US. And you're talking about replacing 300 million cars with platinum and replacing the catalyst every couple of years later.
And don't forget peak oil is a scam and man-made global warming is also a scam.

A Palmerston North inventor is driving the length of New Zealand in a car powered by cooking waste from McDonald's to try to prove that vegetable oil can be used as a reliable motor fuel.
James MacDonald hopes to patent the engine modification he has spent two-and-a-half years developing.
"You can use hemp oil, vegetable oil, tallow, chicken fat etc, so any hydro carbon chain," he says.
His trip from Bluff to Cape Reinga is expected to take a fortnight.

Any idea what the distance is? A fortnight is two weeks and I didn't think NZ was that large. Or maybe running a car on these oils doesn't provide the same amount of power, the car can't travel as fast.
People have been variably working on using such oils for years, and I've heard or read of some people actually getting this to work. But I think some mechanical changes need to be made, if I recall what I read on this.
There are other alternatives and with with some people who've been experimenting have gotten cars to provided as much as over 200 mpg. There's one university prof. in California, and some company in what I believe to recall is Germany, both getting cars to provide this astounding efficiency. The guy from Calif., the article I read on his story says that the car doesn't constantly provide this efficiency, for it only last for a relatively short amount of time, average-wise anyway. But he said that an average individual using a car to commute to and from work, so say 20-30 miles, these people can average somewhere around 80 mpg, which is still great.
I forget what those involve, but believe that if we talk about gasoline, hydrogen and electricity, then this pretty much covers the possibilities of what I had read, if I recall correctly. "Trick" is, to find those bookmarks, for those articles were bookmarked. Yet I imagine a Web search should be relatively easy to perform.
If you want those URLs, then let me know and I'll try to find them.

Hydro-carbons? Anyone know what the pollution is for burning plant oils? Given these are forms of hydro-carbon, and petroleum, I believe anyway, also is, what makes one less polluting than the other?

I personally don't do the maryjuana scene, but hemp is the future of alternative fuels. Too bad that the greedy nature of humans have ruined our enviroment with crude oil based products. There have been many alternative fuel developers that studied the hemp seed oil. In fact, a standard diesel engine can be converted to run on pollution-free hemp seed oil. They have also developed home heating conversions as well. How long are we going to allow the rich oil barons dictate our lives with enviromentally threatening fuels such as crude oil, even the extraction of crude oil causes pollution...

From the period after World War One to the beginning of World War 2, there was a significant warming of the planet. That was a time when carbon dioxide emissions wasn't even a problem.
I just don't think carbon dioxide is the problem and I especially don't think it's warming. I think it's cooling and we're up for the second ice age. If it wasn't for chemtrails, we've already be in it because we're at the end of the ice age cycle.
If that doesn't prove my point, you can stay ignorant if you want. I won't spend more time on this.

How to make Biodiesel
Lee wrote:
Biodiesel!
What is biodiesel? Simply put, it is diesel fuel that is made from vegetable oil. It will run in any unmodified diesel engine. It has many advantages over petroleum diesel fuel such as: 1) It burns cleaner 2) It has a higher cetane rating (less knocking) 3) It has better lubricity 4) You can make it yourself from used vegetable oil (a waste product) often for less than the cost of petroleum diesel.
How to make your first batch of biodiesel:
You will need the following things to make your first batch:
1) At least 1 Litre (1.1 Quart) vegetable oil. Canola oil, corn oil, soybean oil, etc will suffice.
2) A variable speed blender with a slow speed option. Use one with a glass pitcher only. The methanol that is used in this process will "eat" a plastic pitcher. Make sure that this blender will never be used for food products again.
3) A scale that will accurately measure 3.5 grams (.12 oz). I use a triple beam balance available through Edmund Scientific. Search the site for the keyword "balance". A good scale will cost between $100 and $200 and is a good investment. However, if you are on a budget, you can get the Edmund Scientific "Carry-With-You Twin Beam Balance" (Stock Number: CR30360-28) which will weigh up to 4 grams. This costs $25.
4) 1 bottle Red Devil Lye Drain Cleaner (Sodium Hydroxide) available from you local hardware store. Make sure the label says "contains sodium hydroxide". Most other drain cleaners are chlorine (Calcium Hypochlorite) based and will NOT work! Notice: Lye is poisonous! Take all necessary safety precautions!!
5) At least 200 milliliters (6.8 fl. oz) of methanol (Methyl Alcohol or "Wood" Alcohol). Methanol is widely available in 12 oz. quantities as "gas tank antifreeze" in auto parts stores, hardware stores and even some grocery stores. Popular brands include "Heet" and "Pyroil". Read the label carefully and make sure it says "contains methanol"! Many gas line antifreeze products contain isopropyl alcohol or "isopropanol" and will NOT work! Methanol is available in larger quantities as racing fuel through some racetracks that cater to drag racers and some "high performance" auto parts stores. Keep in mind that Methanol is both poisonous and flammable. Take all necessary safety precautions!!
6) A glass container that is marked for 200 milliliters (6.8 fl. oz). We like to use a beaker.
7) A glass or plastic container that is marked for 1 liter (1.1 Quart)
8) A wide mouth glass or plastic container that will hold at least 1.5 litres
9) A common spoon (preferably plastic or stainless steel).
10) Safety Glasses and Rubber Gloves! Methanol and Lye are extremely poisonous and must not come into contact with skin or eyes! Methanol is a poison that attacks the eyes (ocular nerves) even if it comes into contact with your hands. Use extreme care when blending the methanol and lye, as the blender can spash the chemicals around. Put on your glasses and gloves BEFORE opening the chemicals! Do your work close to a sink or hose, or have a bucket of water handy to wash any part of your body immediately if it comes in contact with these chemicals.
Step 1: Get organized in a well lit, well ventilated area! This process is best done at or above room temperature (70 degrees F or 21 Degrees C). Temperatures lower than 60 F or 15 C may cause an incomplete reaction. Plan for spills by spreading paper or plastic on your work surface. Put your safety glasses and gloves on before opening any chemicals!
"Heet" is a popular brand of "gas line antifreeze" in the US. It is widely available in auto parts stores, hardware stores and even some grocery stores.
Make sure that the label says "Contains Methanol"
Measure 200 milliliters (6.8 fl. oz) of methanol
Pour the methanol into the blender.
Notice the glass pitcher on the blender.
Weigh out 3.5 grams of lye on your scale. Notice that we use a white piece of plastic to hold the lye. The weight of the plastic is 4 grams, so we set the scale to 7.5 grams.
Turn the blender on "slow" speed and slowly add the lye to the methanol. You now have a mixture called "sodium methoxide". The methoxide must be used right away to make biodiesel. Do not plan on making a large batch of methoxide and storing it for use later. It loses its potency over time.
After the Lye has completly dissolved into the methanol (about 2 minutes), add 1 liter of vegetable oil to the blender. Blend on low speed for 20 to 30 minutes. The ideal speed for this process just barely creates a vortex or "tornado" in the oil without spashing the mixture around or frothing it up.
After the blending is complete, pour the mixture into the wide mouth jar. It is advisable to label all containers used in this project as "POISON"! And of course, keep all of this stuff away from children!
After about 30 minutes to 1 hour, you will notice a layer of darker colored glycerin settling to the bottom of the container. The lighter layer on top is biodiesel. Wait another few hours for complete settling. At that point, you can carefully pour off the lighter biodiesel from the top and discard the glycerin (or save the glycerin to use in soapmaking). An alternative would be to use a pump to remove the biodiesel from the jar. You are done!
It is always wise to use a "diesel fuel filter/water separator" with any diesel engine. These are available through some auto parts stores or www.westmarine.com. A good model is the Racor 120AS diesel fuel filter/water separator (West Marine .. 411348).
Biodiesel has a solvent effect on natural rubber hoses and seals. While newer diesel engines have polymer hoses and seals (such as Dupont's "Viton" brand), older engines may need to be outfitted with new hoses and/or seals made of viton. Since most diesel injector pumps don't have rubber parts directly in contact with the fuel, it is usually easy to replace hoses and seals without any major dissasembly. A fuel mixture of 20% biodiesel and 80% petroleum diesel (called "B20") will have no effect on older natural rubber hoses.
Biodiesel will "cloud" at temperatures below 55 degrees F (13 degrees C). While this "clouding" is easily reversible by raising the temperature of the fuel again to above 55 degrees, it may cause temporary clogging of your fuel system, thus stopping your engine. Petroleum diesel fuel (Diesel ..2) can be used down to -10 degrees F (-24 degrees C). It is advisable to use a blend of at least 50% petroleum diesel with your biodiesel if you are going to be operating in cold weather. You can experiment with different blends of biodiesel and petroleum diesel to determine what works best. Simply mix up batches of fuel with different ratios of petroleum diesel and biodiesel in glass jars and put in a freezer. Use a thermometer to determine the temperature of the fuel. Periodically check on the fuel to determine at what temperature it gets cloudy. This temperature is the "cloud point". It is best to determine this point at home before you head out on the road and get stranded in a snowstorm because your mixture is too rich in biodiesel. Of course, if you are going to be operating during the warm months, or in a warm climate, you can use 100% biodiesel with no problems.
Peak Oil data is convincing, no matter what Alex Jones says.
On the other hand, you have Hemp and grain alcohol you can run your cars on, when oil begins skyrocketing. There will be definite dislocations of the economy, but after a year or two, things will smooth out and we will use these new, easily available fuels, not solar power, which is still too expensive. Same goes for those stupid 'fuel cell' vehicles. How stupid is that? You still have to get the friggin' hydrogen split off and pumped into the cell. Alcohol is cheap, effective and proven. And the U.S. has shitloads of cornfields.
Oil prices can only go so high; then there will be 'substitution', i.e., corn/alcohol. There will be 'blends' and then someone will invent a converter so you can run it straight.

For alcohol from what I remember; it requires a carbeurator adjustment, and needs priming in cold weather. It also clears off the gasoline sludge in the gas tank which may cause issues. I wonder if they still have government grants for building our own distilleries (USA). For farmers last I knew this was more a matter of having time to do it than cost considering the grants, the corn, the by-product, etc.

Mankind has had an impact on this planet from his burning of fossil fuels, his over-consumption and wasteful activity.
And btw, temperature increases have been accelerating for a long time now in the past 100 years; with only occasional troughs but that hardly goes against the general global trend in increasing mid-level temperatures and SST's (sea surface temps). I also recommend you check out the English CET....it gives a good impression of AGW at temperate maritime latitudes (which are more likely to be affected by AGW due to the lag-effect of warming seas) because of its very long time-series - i.e. the longest recorded temp series in the world.
I also post on a forum called Net-Weather. I would like to see you post your skeptic arguments in there; as it seems that every skeptic who has made a case has been proved wrong by the knowledgable people\meteorologists who reside there.
