Hello Reinhard Thanks for the reply.

Well, thankyou, that's what I thought. There's a Biofuel list member in Australia who runs an old Lister in straight chicken fat. But there seem to be different kinds of Listers. I wonder if the Lister sold in the US, for instance, is the same as the type made in India and Sri Lanka, and probably in China too. Is it a generic name as well as a brand? Like Petromax - you know the Petromax lanterns? Nice things, burn biodiesel or ethanol just as happily, and you can put a stove on top. They're also made in India, Singapore, Taiwan, China, but not quite the same, and not always the same quality as the original. In the case of the Lister though, the Third World type might be better (tougher). >A UN-project took this over and they were disseminating the Lister >type diesel engines with plant oil.

Reffed below - we mention Elsbett there, and other SVO systems. I think the Elsbett and Biocar systems from Germany might be the only good way to run a modern DI on SVO. But I think WVO would still need pre-treatment - they don't cover WVO in their warranties, do they? My view of it is that if you're going to be sure of not messing up your DI and since it needs considerable pre-treatment anyway, you might just as well turn the WVO into biodiesel and be safe and sure. But again, the ACREVO study mentioned below really deserves some follow up - adding 9% of 95% ethanol to SVO brought combustion characteristics (and emissions reductions) that a DI could probably live with quite happily. DIs could then use the same modification kit as for IDIs rather than having to be converted. >At the 7. of July there is a meeting of SVO drivers/users in >Germany.
