Converting your vehicle to run on veggie oil is a good move economically and environmentally. And here’s what BP and Exxon don’t want you to know: it’s not hard to do.

WOULDN’T IT BE GREAT to pack-up the car or the SUV for a weekend excursion without fretting over the cost of fuel? Or take that road trip you and your friends keep talking about? All with no concern about pumping all of your hard-earned cash into the gas tank. Heck, it would be great just to drive around town without that concern. Here’s how you can do it.

1. Commitment

This will not happen overnight. Nor will it work if you just want something for nothing. There are some up-front costs, but more importantly, it’s the dedication of your time and energy that puts the money back in your pocket. You’re going to give up the quick convenience of the express station, so you have to truly believe in the value of what you’re doing. But once you make this determination, the hardest part is already done.

2. The technology

The technology has existed for almost 100 years. Rudolf Diesel designed his engine to run on corn oil that he had collected on his Iowa farm. He wanted a more efficient way to run his farm machinery because gasoline had reached a staggering $0.05 per gallon! Look it up yourself – the diesel engine was intentionally designed to operate on vegetable oil, not toxic petroleum byproducts. And that’s all you’re going to do.

3. Sourcing your vegetable oil.

Every restaurant and probably most bars in your community are currently paying somebody else to come and haul away their waste vegetable oil from the fry-o-laters.

In your local supermarket, vegetable oil retails for about $10/gallon, almost three times as expensive as regular unleaded gasoline these days. You want free vegetable oil. Well, every restaurant and probably most bars in your community are currently paying somebody else to come and haul away their waste vegetable oil from the fry-o-laters.

That’s your source. Develop a relationship with the manager or owner of local establishments. Tell him or her that you’re interested in collecting their waste vegetable oil. Offer to do it for free.

Make sure they use NON-HYDROGENATED oil. You do not want that creamy based oil. You may have to supply them with a collection barrel, and you want to make sure the manager can depend on you to collect at regular intervals so he doesn’t have to worry about it.

4. Processing the oil.

The oil that you collect is not ready to burn. It must be heated and filtered. You will need a couple of barrels’ worth of space in a garage or basement where you can set-up your little processing station. If you don’t have the space, consider getting a co-op going with friends or other people in your community who do.

In any case, the system is not complicated, it just requires a little bit of money to set-up and then a regular bit of attention to generate usable oil. There are many different methods for this process, but they all essentially involve heating the oil in one tank, then pumping it through some filtration device to a second tank.

The whole point is to remove any water and particles that have collected in the oil during use. Lots of people have posted their processing plants on YouTube or other veggie forums such as Fryer to Fuel. There is not ONE way to do it, and you will have to devise the best way for you to do it with regard to your space, time, and budget.

5. Lining up your vehicle.

Now you need the vehicle to utilize all of this wonderful, free oil. Hopefully you aren’t terribly attached to whatever it is that you’re driving now. The decision to run on veggie oil limits the type of vehicle you can drive because only certain models are produced with a diesel engine.

Maybe you’ll decide that, since you’re going to be driving for free anyway, you might as well drive the biggest, baddest rig you can find.

The good news is that these models are quite nice. Volkswagen has offered diesel versions of the Golf and the Jetta for years, and the list now includes the Passat. And Mercedes has several sedan models and even a wagon with the available diesel. And fortunately for the checkbook, you don’t want a new one anyway. The older models make better conversion candidates because the engine is less complicated. A little bit of research (check greasecar)will turn-up a car you like that fits your budget.

Maybe you’ll decide that, since you’re going to be driving for free anyway, you might as well drive the biggest, baddest rig you can find. The Big 3 American auto manufacturers produce diesel powered trucks and SUVs that also make excellent conversion candidates. Again, the slightly older models offer a little more ease of conversion. The bottom line is, you should be able to find a ride that makes you happy.

6. Conversion

Conversion kit. Photo by Cody Simms.

Now you have to tweak the fuel system to accommodate your veggie oil. The major issue is temperature. There are all kinds of conversion kits for sale from different companies on the internet. They can cost as much as $4000.00. And they all insist that if you can read instructions you can install the kit yourself.

Or you can go to one of their authorized installers and drop another G for them to do it for you. The money saves you the hassle of doing it yourself and buys you peace of mind and presumably customer service, should a problem arise.

The truth is that most of these kits are just a compilation of parts and pieces – hoses, gauges, valves – that you can buy cheaper from a direct source. And if you or someone you know has any degree of comfort around an engine, then yes, you can convert your car yourself. Just research. Again, there are lots of community forums about converting to veggie oil, and even a bunch of videos on uTube. It’s the commitment issue again. Understanding how the process works will give you the ability to address it.

7. Notes on cost

Nothing is truly free. Assuming that you trade your current vehicle for one of equal value, the start-up cost for your alternative fuel program, including your processing plant and the conversion, will likely top $3000.00 even if you do it all yourself.

Again, a co-op is a good idea: you can gather people you trust to help curb the initial cost of the plant and to share collection duties and split time actually processing the oil.

If you spend $50/week on fuel, it will take one year and two months for your program to pay for itself.

If you spend $50/week on fuel, it will take one year and two months for your program to pay for itself. And of course there’s your time to collect and process the oil, plus the bit of energy needed to operate the plant. Be sure to find out if your state has an alternative fuel road tax provision on the books too, so you can jump that hurdle.

And thereafter you’re driving for free! And in the meantime that’s 50 bucks each week to take your girl out to dinner or contribute to your IRA or whatever. Plus it’s better for the environment, recycling oil and no carbon emissions. And when you want to take that trip, the WVO Network, a nationwide community of veg-heads, will propel you around the country.

8. Drive!

This might all seem like too big a deal. Well, putting several thousand dollars a year back in your pocket is a big deal. Forgetting the major cost of road travel is a big deal. Conserving resources and protecting the environment is a big deal.

Converting to veg allows you to contribute to softening a global crisis and improves your personal bottom line significantly over the long term. The first time you flip that switch and you’re running on straight veg, the headaches and expense of converting blow right out the tailpipe!

  • robert saint amour

    if every restaurant in my valley of 50,000 people were to give me their used oil i could run a maximum of fifty cars out of about 15,000

    i ran many vehicles for years on this and wood gas

    most communities i know are already maxed out, and only a fool like bush would consider using food stuff to burn in their hummers

    one thing about early diesels you missed, it was hemp oil that started it and to some extent flack seed, diesel oil came with the Rockefeller’s and their interest in refined petroleum oil, which i like to call petrosexuality

    nothing new about bio fuels, pearl harbour was attacked by zero’s all using methanol and lubricated with veggie oil, just not a good idea today

    i applaud your efforts but i really think your time is limited, the uk already have a thriving industry converting used oils and their price has gone through the roof making them very close to the price at the pumps, about 15p difference

    i hope you run your vehicle for a long and prosperous time…and that your neighbours remain oblivious, if it were me, i would take this info off this site, most others have, if not it could mean the end of your free driving

    10 Ways to prepare for the post-oil society

    #1 – Expand your view beyond the question of how we will run all the cars by means other than gasoline. This obsession with keeping the cars running at all costs could really prove fatal. It is especially unhelpful that so many self-proclaimed “greens” and political “progressives” are hung up on this monomaniacal theme. Get this: the cars are not part of the solution (whether they run on fossil fuels, vodka, used frymax™ oil, or cow shit). They are at the heart of the problem. And trying to salvage the entire Happy Motoring system by shifting it from gasoline to other fuels will only make things much worse. The bottom line of this is: start thinking beyond the car. We have to make other arrangements for virtually all the common activities of daily life.

  • http://greenpostcards.typepad.com Sarah

    I agree with posters above that we need to look beyond cars alone for transportation. But there are some trips where only a car is practical — if I walk or take public transportation to work each day do I save up enough eco-points to drive three hours north to see my family? How ’bout if I drive a veggie car? Thanks, Brad, for the WVO article. My husband and I have been thinking of converting for a couple years and am now seriously considering it. I’m looking a a company called Golden Fuel out of Springfield, MO. Anybody heard of them or used their products? Looking forward to the day when I can roadtrip to some of the eco-destinations I blog about (http://greenpostcards.typepad.com) oil- and $-free.

    I had a dream a few years back of getting one of those old diesel Jettas and figuring this whole thing out. Well, now I’ve got your article, and I recently learned how to check my own tire pressure (!) so I guess I’m sort of on my way… :P

  • http://www.shareyourride.net Carpool Guy

    thats an interresting article.
    however, Rudolf Diesel was a german engineer and has never been to iowa. he got a petent on his engine design in 1893. it was John Froelich who and invented and build the first practical gasoline-powered (no corn oil here!) farm tractor in 1892 in iowa. Diesel build the first working version of his engine design in august 1893. :D

  • Richard

    Great Read! Remember that most states require that you pay the ‘road taxes’ on the fuel you produce/consume regardless of whether you got it for free or not. You do not want a nasty audit form the State Tax Man to find that you retroactively owe thousands of dollars.

  • UM Engineer

    Great interest-provoking article. However, saying the engine has “no carbon emissions” is completely false. Burning vegetable oil still releases carbon dioxide and carbon monoxide as described by the classic combustion process.

  • http://azbushman.com John

    I love the fact that more and more people are getting interested in trying to make a difference. On the other hand I have been hearing more and more about using veg to run autos. It really is a great idea, but what happens when the demand reaches a point were the cost of veg rivals that of gasoline. I will in fact become a capitalist endeavor. Companys, businesses, and corporations love to that money coming in. Especially if we have no choice but to buy. Please don’t take this the wrong way, I meant nothing more than an opinion.

  • Jeff

    Unless someone has a matter-transporter (aka Beam me Up, Scotty!) up their sleeve, the cars will stay. The cost to restructure a single major city in the US into a “walking city” alone would eat Exxon’s profits for the next 5 years or more. And abandoning the current cities and building new “walking citys” would cost as much or more, if you could get people to move.

    Veg burning is a cool idea, but as many point out,the day will come where it will cost as much to produce enough as it costs for gasoline, if for no other reason that corporate greed.

    What about veg and methanol mixed as a gasoline replacement? Or better yet, burning on-board generated hydrogen?

  • Maryann

    I recently returned from France. They grow a crop called rapeseed for canola oil and we were told that this oil is used in all their buses.

  • http://ooyes.net website design

    I’ve seen quite a few people do this successfully, but be careful you can really damage your engine if you do it wrong or use bad oil.

  • SNF

    UM Engineer: “However, saying the engine has “no carbon emissions” is completely false. Burning vegetable oil still releases carbon dioxide and carbon monoxide as described by the classic combustion process.”

    “No carbon emissions” is a poor choice of words, as you point out. It would be better to describe this process as “carbon neutral” because the CO2 that you’re releasing into the atmosphere was originally sucked out of it by the crops that went into making the oil (carbon fixation/photosynthesis).

  • ConcernedCitizen

    Great idea! Please be cautious of using, storing, manufacturing or distributing biofuels without the proper paid-for govt issued license. For this is the only way they can regulate and collect their portion of motor fuel taxes.

    This elderly couple in Illinois has been doing it for years and found themselves being harrassed by authorities. Don’t know the final outcome, but the scare tactics of heavy fines, felony charges, and possible conviction with 5 year jail sentence probably wasn’t what the couple expected for being creative and doing what the president and everyone else has been saying to reduce our need for foreign crude oil.

    You can also put additives into the fuel to make the car run without the conversion kit. I don’t know the exact formula, but I know kerosene is one of them. It’s not hard to do; I’ve seen an eighty year old man do it (he runs his house on a generator from it, his cars, pumps, etc…)

  • http://www.reelectnoone.com Paul Kruger

    Yes this works and works well. However it won’t stay free once more people jump on the idea because restaurants will start to sell their old oil to the highest bidder. In some areas they already get paid for their oil by companies that collect it and processes it for fuel and other uses.

    If you have a diesel powered vehicle now and can get the oil, and are willing to do the work you can drive cheap…for awhile and within range of your stockpile of oil. Won’t help you on the open road after your first tank is empty though.

    Don’t look for a diesel if you are buying new now.

  • http://www.maletic.org dusan maletic

    Unfortunately the main premise of this have been bypassed by the market forces for at least a year or so. In most places owners of the used oil are now paid for it (they no more pay for it to be taken away). On a good side: an industry have emerged to profitably collect used oil and recycle it/manufacture bio diesel. On a bad side – in most places you will be accused of theft if you take the used oil without permission (and you are unlikely to get permission).

  • Mike Cochenbalz

    Hmm… running my car on oil eh? Well, I drive a Buick Park Avenue Ultra. Aside from the fact that it’s a giant, monstorous gas-swilling machine, they don’t make a diesel version. Find something useful to do with gasoline engines, you corn oil guzzling weirdos. Nobody uses diesel.

  • bob

    Hi,

    No, no … the ‘merkans didn’t invent the diesel engine … please get your facts straight before posting. That said, I am a believer in the original closed loop crop/fuel cycle as it was intended initially.

  • http://makesomethinghappen.net/ Alex Steed (of Make Something Happen)

    I appreciate the information. I will surely be forwarding this information accordingly. I love that I spend a lot of my time in Portland, Maine, where the conversion to these sorts of innovative, alternatively fueled vehicles became less-than-a-rarity a few years ago.

    So many thanks again!

    FYI Diesel engine, invented by Rudolph Diesel in Germany was originally designed to run on peanut oil. There was no such thing as diesel fuel !

    This is a move back to the origins of the diesel.

  • Greg

    I think this article and the idea is kind of stupid. C’mon, do you really want to shell out 3 grand to go through such a hassle just to fill your car? Just get a 4 cylinder of some sort and save yourself a ton of work. Or just ride a bike and take the bus more often. When someone figures out a conversion for a normal gasoline combustion engine, then maybe it will be interesting, but with the total diesel cars out there equaling about 1% of all cars, this article is talking to a very specific segment of the population. spend more time writing something useful to the other 99% of us.

  • Gabe

    Point 7. in the article is closed with this phrase “Plus it’s better for the environment, recycling oil and no carbon emissions. “…No carbon emissions???…This is a huge mistake. Burning oil of any kind, even vegetable source, causes carbon emissions. Carbon emissions stands for carbon dioxide.

    hello
    im a diesel mechanic, this grease car idea has caused alot of problems when people dont get the full story. grease needs to be very clean and no moisture at all. the grease needs to be 160F for it to burn. sure it will run at a lower temp but you are very inefficent. and pollutes.
    also you shut your engine off with the grease in it and cools off it will not start again without major engine work. the last pump i rebuilt cost the customer $1200 and was pissed and removed his grease conversion ($3000) .
    i have seen it run and run very good but only on cars that travel many miles at a time . short trips (20-30 miles) just dont make a good reason to convert.
    also the grease is that easy to locate. these eating places have been in buisness and have someone picking up their oil that are in the buisness of recycling.
    just a word of caution!!!!

  • http://yahoo.com hobbs

    great job hippie

  • RodS

    This is a great idea for the environment but not really for the pocketbook. As was mentioned earlier, grease is no longer free. In fact, there’s been a spate of grease thefts across the nation. The companies may have at one time been paid to haul off the grease but that time has long passed. Those companies now PAY the restaurants for their grease and compete for business (and have done so for quite some time now).

    This article was poorly researched which is a shame as I have found much on this site that is great even for a digg/deli sponge site.

  • Rabbit

    Idiotic.
    You’re assuming that you’ll find someone else with a vegetable oil setup where ever you run out. Get 10 miles from home, and run out of fuel? Oops.
    Not to mention, I know my time is worth a lot more to me doing other things than running around gathering someone else’s used oil (you’ll need a vehicle to drive around and pick it up, btw), and then taking the further time to distil it and then actually fill up.

  • A&A

    I think we should go back to riding horses. At least then, we wouldn’t need to wasted energy, filtering used vegetable oil (fresh vegetables for fuel.)

  • Michael

    I have a question. While this is a cheap alternative to gas, how good is this for the environment. I’ve heard that using oil to power your car would actually increase greenhouse gas emissions. Can anyone confirm/deny this?

  • http://www.everydaynormal.com Dave

    I have always wanted a bike car, since I am too lazy to keep balanced for so long. Maybe I could lose weight. Wait I can run my car on Bacon grease. Double Bonus!!!

    A Volkswagen van, living with your mom and digging through restaurant trash bins for used oil. What a farfromlivin life. Why dont you shave and wash your clothes too?

  • Martijn

    You people seem to forget that the government will not easily allow this – it will miss out on the taxes it collects on regular fuels. You should realise that you are liable to get fined for this. (At least I assume this will be the case. I know for a fact that it is illegal to run your car on anything else than pumpbought fuels over here in Europe.)

    When petroleum alternatives become available at regular petrol stations they will not be cheaper than the current fuel prices. (Environmentally friendly and cheap are not exclusive, just unlikely). It takes more resources to produce biofuels and thus the price will most likely be higher still.

    While it is an excellent article, having people run their own oil based cars is not exactly viable.

  • dog food

    hmm weed grows fast enough. a few male plants and you’ll have enough to make your own hemp oil processing plant.

  • Shari

    I agree with those who say that finding free oil is a real onion in the ointment, though the article is interesting regardless. The important thing is for people to start thinking outside the box.

    I like the suggestion to go back to riding horses. When I was a kid, we used to ride horses or sulkies drawn by horses to town for fun. We could buy groceries this way rather than drive our car. I lived in the country and this was about 25-30 years ago. The main problem is that the roads full of cars don’t facilitate this sort of transport. They’d have to be changed or rules of the road altered or there would be a lot of accidents from motorists who drive like speed demons.

  • Pete

    I was just reading that mass transit use is at an all time high in many US cities. About time for that to happen, although cities are struggling to fund the increase. I wonder if towns will take a peek at veggie powered buses…to your knowledge have any towns done that before?

  • Andy

    Good article. I ran bio-diesel’d Mercedes and Volkswagens for about two years. The problem is, most people have already got contracts to receive the veggie oil from most restaurants and businesses. I would not advise anyone to invest in one at this time though. If you factor out the cost per mile, it is approaching what a fuel efficient compact vehicle will do (30+mpg). When I was running a mercedes, I was buying the cleaning processed veg oil from a trucking company for 1.75 a gallon (when diesel was still around 2.99 a gallon). When i started vegging, I could get away with at best .03 cents a mile in the Volkswagen and .08 cents a mile in the Mercedes. Now it costs close to .10 cents a mile to run the Volkswagen and the Mercedes are long gone. I can get .10 cents a mile with a little hypermiling in my Gas engined Volkswagen.

  • aNon

    Get your head on straight
    “Plus it’s better for the environment, recycling oil and no carbon emissions.”
    Burning = carbon emissions
    Most oil taken from fast food places is recycled anyways to make items such as soap.

  • Ziggy

    To the person claiming “HHO” gas improved you milage:

    That’s impossible. Everyone who is jumping on this HHO bandwagon is being taken.

    You see, it’s a simple matter of conservation of energy/mass. In order to make the HHO, it requires electrical energy to facilitate the electrolisys. The electrical energy is produced from your alternator, which is in turn converting a portion of the mechanical energy from the engine. What process is it that turns the engine? Combustion the the gasoline. So, in order to make the HHO in question, you have to burn gas. Even if you considered the process to be 1:1 (i.e. an equivalent amount of energy is produced in HHO gas that was consumed in gasoline to make it), you’d be breaking even.

    That will never be true as the combustion of the gas in the first place has energy losses to waste heat, mechanical friction, hydraulic friction and just general inefficiency. In actuality, only approximately 10% of the energy of the gasoline, under normal circumstances, goes into moving the car down the road and making the accessories run.

    Additionally, the energy density of gasoline is considerably higher than burning hydrogen and oxygen. Adding a current draw to the alternator to make the hydrogen and oxygen, for which, in a perfect world you’re only getting 1/10th the equivalent energy for that you started with in gasoline, would be better spent just moving the vehicle. So, in effect, whatever amount of gasoline you consume making HHO, in the best case, you’ve dropped your efficiency by 90%.

    Don’t buy into the hype; the laws of physics just doesn’t allow it. Just think of it this way, you’re putting energy into splitting the hydrogen and oxygen apart, only to try and reclaim that same energy by putting them back together through combustion. Not accounting for inefficiency losses in that process alone, you’d only be getting a 1:1 energy conversion. It’s a waste of money…

    “Rudolf Diesel designed his engine to run on corn oil that he had collected on his Iowa farm.”
