    Yes you can put SVO into a diesel engine, BUT it will feck up your engine.

    http://journeytoforever.org/biodiesel_svo.html#putin

    The central problem in using vegetable oil as diesel fuel is that vegetable oil is much more viscous (thicker) than conventional diesel fuel (petro-diesel, DERV, "dino-diesel"). It's 11 to 17 times thicker. Vegetable oil also has very different chemical properties and combustion characteristics to those of conventional diesel fuel.

    If the fuel is too thick it will not atomise properly when the fuel injectors spray it into the combustion chamber and it will not combust properly -- the injectors get coked up, leading to poor performance, higher exhaust emissions and reduced engine life.

    'Just put it in and go'
    Myth: Just put it in the tank -- any inline injection pump is happy on cold veg-oil, they don't mind starting on cold oil, especially with an older Mercedes.

    We hear it every summer, we don't hear much of it in winter though. An experienced SVO'er summed it up on one of the Internet mailing lists:

    "I am tired of hearing people say that they can dump veg-oil in an old Mercedes, do nothing, and it will be fine. It's abuse of a fine engine, it causes poor, smoky cold starts, the emissions will not be as favorable as they should be, and the starter, glow plug, lift pump, battery, and injection pump will all be subjected to higher than usual stresses."
    We agree.

    Mixing fuels
    Myth: Mix it with diesel fuel or kerosene, then just put it in and go.

    Examples:

    "I've been running a vegoil/diesel mix, 50/50 winter 70/30 summer."


    "I'm running on about 50% petro-diesel to 50% veg-oil, no problems!"


    "I use 90% WVO and 10% kerosene as my standard summer fuel."
    Responses from seasoned SVO users:

    "Your cold starts will begin to deteriorate, your filter will probably start plugging, your injectors will get coked up, setting the stage for ring sticking, glazing of the cylinder walls, increased lube oil consumption and eventual engine failure -- if you can continue to get the thing started in the morning. More than 20% or so veg-oil in the diesel is not a good plan for more than short term 'experiments'."


    "Mixing veg-oil and diesel isn't advisable unless you heat all the fuel."

      "Alliance Against Urban 4x4s handed a 5,000-signature petition "

      Not that I know of one but pray what would be the case is someone came out with a hybrid 4x4.

      As it is this is nothing more than envy. Those who do not have one want to make sure that others cannot either.

        Lexus already do one apparently.

          I think the original Diesel engine was specifically designed by the man himself to run on vegetable oils and was altered at a later date to run on mineral oils.

            Indeed. It was peanut oil.

            A modern diesel engine will run on on Straight Vegetable Oil, but will suffer and end up in the scrap yard double quick.

              Yep. Older engines seem to tolerate it quite well though. I know of diesls that have done 50k plus miles on SVO with no problems.

                I too run 50/50 diesel to straight veg oil. I don't heat it, but I do change my fuel filters every 6000kms

                  I ran a Land Rover series II diesel on kerosene once. The thing knocked a bit but it ran quite well. Above about 20 mph was seriously uncomfortable. Killing the ignition though was invariably pointless as it ran for about 10 seconds after pulling they key.

                    5th gear had a feature a couple of weeks.

                    What happens if you put petrol in a diesel and what happens if you put diesel in a petrol?

                    Diesel runs nicely with a bit of petrol in the diesel.

                    Petrol runs like tulip with diesel added to the petrol.

                    Both bangers survived after filling up with the proper fuel and running it through.

                      Having knackered a Rover 200 doing precisely that, yes it does!
