Frequently Asked Questions

Where can I get vegetable oil?

Most of the time large volumes of vegetable oil can be  obtained from a local restaurant or takeaway shop. Some businesses will offer the used oil at no charge, as they pay to have it removed, and other places may charge a fee.


It pays to research which business to use because ideally  the cleanest oil is the best oil as it makes less work for you. The business  owner may be happy to supply the used oil in the container they received it in  or you may have to supply your own.  It  is ideal for both parties to agree on a regular collection day.  To avoid loss of supply and / or a meat  cleaver to the skull, be sure to adhere to the dates agreed on!

Won’t my vehicle smell like mackers?

No, more like a BBQ! And that's great because once you change,  you'll never want the smell of diesel again. Just hope that nobody following  you is on a diet because all they'll crave is BBQ!

Can I do the conversion myself

Yes. If you can perform maintenance on your car, to the  point of changing a radiator hose and installing a stereo then you should be  able to install a veggie conversion kit. Normally allow 1 to 2 days to finish  the installation.

  

Can I transfer the kit to another vehicle?

Yes! Our  system is recyclable! Simply remove all components and restore the vehicle back  to its original condition. We can remove and install the kit into another  vehicle for a labour only cost provided no more parts are needed for the new  vehicle (hose clamps, heater hose etc).

  

Can I just put Vegetable oil in my tank without a conversion?

Yes, but be warned it can damage your engine and block your fuel lines and filters and in the worst case it could even seize your injector pump. The older Mercedes could handle it as they were very veggie tolerant, but  most other vehicles are not unless the vegetable oil is heated before reaching  the injector pump. Cold vegetable oil has poor atomisation because of its viscosity and also will create undue stress on the injector pump.

How do I filter my used oil at home?

The best and most efficient way of filtering used oil is  through our premium filter bags. We can supply you with a filter bags which can filter your used oil down to 1  micron! Be sure to carry some spares at  all times.

You will need, depending on your circumstances, either a 44  Gallon drum (210 litres) or a 13 gallon drum (60 litres) or both. These can be purchased  second hand from your local farming shop or on Facebook Market Place for around $5-$10 each depending on the shop / person. Once you have a drum you will need to cut a hole in the top  (between 15 -20cm diameter) this will hold the filter bag. Then all you need to  do is pour your used oil into the bag and let it filter out into the container.

We can supply you with a hand pump or electric pumping  system to make the transfer of oil to and from you vehicle a breeze!

What happens if my supply  of Vegetable Oil run out?

Just use diesel, if you are on a trip and can't find a good supply of oil then you can just pour diesel into your veggie tank. Note: Whatever you do, do not let the engine run out of fuel, otherwise you may not start it again unless you take it to a mechanics. (although if it ever happens, fill the tank with fuel and try full accelerator and crank the engine in 20 second bursts and it may start up and run quite rough until all the injectors bleed out the air within the system (or it will flatten your battery) 

 

What about my vehicle warranty?

The manufacturer's engine warranty will not be honoured due to the fact that Veggie oil is not a  recognised fuel, so your warranty will void itself. 

Does Snotta.com offer a warranty?

Yes. We offer a 12 month parts and labour warranty of the actual veggie oil conversion kit. We DO NOT however cover anything related to the engine, any other part in the vehicle or any of the vegetable oil you use.

  

Has anyone had any problems?

Yes. Because vegetable oil tends to clean out the fuel system we have had reports of fuel filters blocking. Although this is to be expected within the first 2000kms, you would expect to use about three fuel filters because of the  existing residue. Once the existing fuel system has cleared then you will only need to change your fuel filter at the recommended maintenance schedules. We have also had injector pump seals expand due to the  chemical reaction between the rubber compound and the vegetable oil. Most of the time only the top seals are affected, requiring replacement. The  seals generally cost between $50 and $100 plus labour. If unless you vehicle is reasonable new you may find that these problems do not occur. It is preferable to ensure the vehicle has been serviced regularly otherwise dirty injectors and old parts may fail after the  conversion.

Will my Diesel smoke any worse?

It really depends on the vehicle, the bigger engine the less smoke, but it really does depend on the vehicle. Some vehicles will smoke more and some will smoke less, although they will smell a lot better

  

Some questions from Email

Question

Hi just wanted to pick your brain for a tick.In the Hilux conversion did you put a heater in the uvo tank? Is it necessary? I am thinking of getting a sub tank for a Toyota cruiser but it may be difficult to heat this tank internally.Can i just use your fuel heater? Do i need 2 fuel heaters? and i dont understand what part the heater box played in this scene.

Answer

No we didn't put a heater in the UVO tank, although in the hilux pictures I would have liked to, but it wasn't viable at that time for the client and also they had a 20 litre drum as their fuel tank. Basically you can get away without using a tank heater in the warmer climate as long as your UVO is in a liquid state. what I would do, if you are adding a aux tank to your cruiser is to have a fuel return back to that tank so the left over UVO from the injector pump can slowly heat the aux tank.  You can use one dual coil fuel heater to do the same job as the two singles as shown on the website.  The fuel heaters job is to heat the UVO to around 70-80c so then the UVO can be pumped with little worry through your injector pump so you vehicle can run.

Question

I am reading with interest your pages on UVO. I have a 1982 Mazda B220 ute, and of course it's a diesel. It has great economy as it is, I'm getting nearly 750ks + on a tank. Anyway, I wouldn't mind giving this UVO a go, as I don't want to set up a processing plant and make biodiesel at home. I have had a good look at the examples you provide and am confident I could set it up, with the help of your diagram. Couple of questions though. Would I only need the dual fuel coil? What is the price of the dual fuel coil? What is the cost of the Pollack device? Does the heat source come straight off the cabin heater lines, i.e. you don't have to stuff around at the radiator? What sort of cost does a second hand fuel filter come in at, and would/could this be off anything? Last one: The picture from your hilux has the tank 20L oil tank in the back on the tray. Does this have a heating coil to it, and whats pumping the fuel/UVO through? No hurry on this, but would appreciate your help/response.

Answer

Great! you have a diesel and would like to convert it, no worries the simple fact is it is easy to convert over if you have any mechanical knowledge. You can use one dual coil with no problems at all. Yes the fuel heater works off the heater lines that go to the cabin heater. The fuel filter, the easiest thing to do is to head down to your local wrecker and get one out of any diesel (but as long as it has the lift pump on top and can fit under your bonnet). The 20L tank in the back of the clients hilux wasn't heated but if you have the cash then just run a return uvo line back to the tank and it will slowly heat the oil as you go. Have a good look at the hilux pics as you will see you will need some fuel line (and up to you how cheap/expensive you go as long as it can handle the heat / 80 degrees), the clear line we used on this job was similar to gas line, it was reinforced fuel line from an auto shop, but if you wish, grab your self some steel line if you can get it cheaper and use that to run the length of your vehicle. The other thing that may make life easier if your oil is a bit thick is to get an electric fuel pump and add that into the system from the UVO tank before it hits the fuel heater, as this will help push the thick UVO through. We can supply you both the fuel filter and electric fuel pump if you wish.

Question

I am going to set up my vehicle on WVO. I see that you guys have kits and parts to suit. The car that l drive is a 94 Nissan Terrano diesel turbo. I am assuming that this vehicle will run on WVO. If this correct can supply me with the parts needed to complete this project. Eg valves, heaters and filters etc.

Answer

I'm assuming from your email you are mechanically minded. I have since had a revamp of the fuel heater from our supplier which has the two units in one unit at a lesser cost, also depending on what and how you want to do the conversion is dependant on cost, if you wish to do things yourself then I would advise you to get friendly with an automotive wrecker and buy another tank for the WVO or we can get one custom made if need be, my suggestion would be to get a small tank of around 10-20 litres made up and fitted to the vehicle for diesel and use your existing tank for WVO (but get another fuel tank sender unit). the fuel line you can buy from BNT or Super cheap autos or if Para rubber is still around then get fuel line from them (strangely enough they are usually the cheapest the clear hose type stuff is fine as long as its fuel line). We can supply you a fuel filter holder like what you already have in your car, then all you'll need is a 6 port valve and away you go basically, and a bag filter for your WVO before you pour it in your tank.

Question

Hi, I'm interested in converting my Peugeot 405 turbo diesel to run on UVO. Can you give me an idea of the cost of the necessary parts for this conversion, I'm on a limited budget so would like to do it with the minimum cost. Your website is great, looks like you know exactly what you're talking about

Answer

I'm gathering you want to install this yourself, so here goes: On a budget, no problem. Firstly acquire yourself a 10 - 20 litre fuel container; this will be for your diesel, as original tank is used for your UVO. This container will end up positioned within your boot (not the best solution of course however, best way to start with on a budget). Next you will require some fuel line – nothing expensive, you just need something that will do the job. As shown on my web site we used the clear reinforced fuel line (almost looks like gas line), this should be available from places like Para Rubber, if they are still around in Dunedin. From BNT or Repco, you will need to purchase some heater hose, and at least 10 various hose clamps. The hose will connect from your heater lines to the fuel heater, and until you actually mount the fuel heater into the car, then the required hose length won’t actually be known.

JUST A NOTE: Depending on how cold Dunedin is, you may have to install a fuel pump to pull the UVO through the fuel lines. We can supply you with a diesel filter unit and T pipe. The T-pipe will be used for the diesel line, this allowing only one fuel line from your aux tank to the front of the car (diesel line). I’ll explain the T-pipe another time in detail. A fuel heater will cost you around $*** delivered, as long as you are not rural, and of course a 6 port valve at a cost of around $***. Basically as you are on a budget (who isn’t nowadays), this conversion is the cheapest way possible, while completing the labour yourself. Once you have your system in place up and running - the money you'll save on fuel will be completely worthwhile. Money saved can always be put towards paying for another tank, purpose built for your vehicle, while also looking at buying an automatic changeover system (final prototype just about finished). Also from memory, if I’m correct, the space under the bonnet with a Peugeot 405 is quite limited therefore, send me through a couple of pictures and I can offer some suggestions If you need it. As I look over this email it may seem quite confusing and long, but underneath it all once you get started and have the picture in your head, it’s quite simple.
