    running on cooking oil

    Has anyone set their diesel up with all the gear to run cooking oil. I've heard of different things to do it right and wrong and would like to hear from someone that has done it. What they used and why.

    dewater it, filter it mix it with enough diesel/tur to keep it thin enough for a facet pump to shift it at 1l/min and stick it in the fuel tank.

    Done.

    Have been doing so for years now. Started off with Dave's setup - dewatered, filtered WVO mixed with diesel or 10% ULP, progressed to a twin tank system with a 65 litre diesel tank, and a 125 litre WVO tank. Starts on diesel, automatically switches over to oil when the oil reaches a certain temperature in the heat exchanger in the engine bay.

    Only problems I've had have been of my own making - usually involving not filtering oil properly and ending up wit a clogged up filter.

    I went the other way, from a setup like mikes (but manually controlled) back to doing most of the work and filtration off vehicle.

    Fozzy, will probably wind up back on the same system as mikes again.


    you dont need any mods once you get north of townsville.

    Probably should clarify - mine was manually controlled, I just had a few thermistors connected to the relay setup for the 3-way valves, so that I couldn't switch over to oil too early. I also had a bypass in the plumbing that allowed hot oil to circulate back into the fuel tank, rather than having cold oil sitting stagnant in the pipelines, filters, if I decided to run off the diesel tank all the time.

    Yup. Wherever you are, it always smells like you're driving past a chippy.

    Hello. Depends how far you want to go... I used to just run straight Canola oil in my 1990 GTD Golf in the UK when it was cheaper to buy oil than diesel. Did this for several years with no problem. The key is cleanliness. A work mate of mine does it and I'm just getting set up to do so using IBC's (meter cubed liquid storage containers). The process starts with waste oil collection, into a container outside, which he does using 44gal oil drums and 12v pump. Once home and transferred, it sits for up to 6 months. The 'product' is then pulled from a point half way up the IBC. The water and sludge is drained off from the base outlet (the waste stinks).. At this point the product is pumped to the top IBC of 3 through a fine steel filter (we use a Kubota digger hydraulic suction filter which is washable in petrol), and again allowed to sit. It's then gravity fed through a washable fine steel filter and standard CAV fuel filter into the second IBC. Here it can sit again, time allowing... From here it goes through a 10micron filter into the bottom IBC, again gravity fed. Once full it is pumped through another 10 micron filter and water trap into a 5000lt rainwater tank. (At this point, if you have time, the process can be repeted through 3 more IBC's as my mate does... Yup, he has 7 IBC's on his farm!!) Here it is ready for use. At this point a 20lt drum is used to mix 18 lt of processed oil and 2 lt of regular ULP. The 'brew' as he calls it is now ready for use! As with each stage, the oil is always pulled from a point approx 600 mm from the bottom of the container, even the finish tank, always allowing the original container outlet to be a water/sediment drain point. (If reasonably clean, this gets thrown back into the Stage 1 tank). Time and patience is key with this if you are serious about doing it. My friend runs 2 tractors (one brand new Kubota), 2 cars and a new Mazda ute (same diesel as in new Fenders) on it without issue. I have tried several tanks thru my Td5 and tractors also without issue.. Thinning with diesel is not worth doing as the amount of diesel required to thin the oil is about 50/50.. and it's still not as thin as diesel. Good luck!!

    I know a bloke who uses chip oil in his diesel ute and diesel houseboat.
    He also uses the large 1000 litre pods as settling tanks and leaves them sit for a long period. According to him water will stay suspended in the cooking oil for a long time. Once settled and filtered, once he is satisfied its right to go he starts his vehicle on diesel then when the temp gauge hits normal he switches over to cooking oil. The cooking oil passes through a heat exchanger unit to he has made up and fitted into his vehicle. Once the vehicle has been started for the day and reached operating temparature there is no need to start on diesel again until the vehicle has been sitting all night. During the day once it's been running he can turn it off, leave it for 3-4 hours and fire it straight up again on cooking oil.
    He also has a small centrifuge unit for portable filtering of cooking oil when he is away travelling.
    It certainly saves him some money.

    my filtration is pretty simple...

    a 240v motor belt drives a power steering pump which pushes the fluid past a 30 micron filter that has a water seperator on it(same microns as tdi/suzi) fitlers.

    the filter is mounted off of a T peice so that normal flow goes straight past the filter leg of the T and returns to the tank to go round again. The outlet of the filter goes into the usage tank. as the oil goes into the usage tank I work out its viscosity using the final filtration and delivery pump after about 20l of oil has been pumped across into the usage tank.

    the usage tank has a smaller filter with a water seperator on it with a T piece and a ball valve. When blending the fuel to get the flow rate at 1l/min I open the ball valve with the pump running (which more or less bypasses the filter) and as diesel/tur/whateverelse untill its flowing at about 800ml-1l/min, multiply that by 5 pour the diesel into the tank, close the ball cock and let the transfer pump keep doing its thing.
