What does ‘carbon neutral’ mean?
It means that biodiesel in use does not affect the overall amount of carbon dioxide in the atmosphere. The carbon dioxide that is burnt off and thereby returned into the atmosphere is almost equivalent to the amount taken out of the atmosphere whilst the source plants are growing. This is not the case with mineral-based petroleum diesel, which pollutes the atmosphere. Does biodiesel really impact positively on vehicle emissions?
Tests have shown that it halves the carbon monoxide emissions, and reduces those of carbon dioxide by nearly four-fifths. Also, it does not have any of the unpleasant side effects associated with the exhaust emissions of petroleum diesel vehicles. Is it technically safer to handle than mineral diesel?
Yes. The flashpoint of biodiesel is more than twice that of fossil diesel (125° C as compared to 50° C). Biodiesel is non-toxic, fully biodegradable, and safer to store than fossil diesel. Can biodiesel be mixed with regular mineral diesel?
Yes. You can mix biodiesel with mineral diesel in any ratio. No problems will be encountered switching between fuels. Are there any modifications required in my diesel vehicle before I can use biodiesel?
You can start using biodiesel, without modification, with the exception of some older vehicles, pre-1995. These vehicles may have natural rubber fuel lines, which could degrade over time. This problem can be overcome by replacing with current synthetic fuel lines. You may also refer to the dieselbob
website for engine specific information.
We also recommend that you replace your fuel filter after your first tank of biodiesel, since biodiesel is a good solvent and will scrub out all the tars, varnishes and gums left by petroleum diesel in your fuel system.
