Thread: Waste vegetable oil???

I looked into it when I was offered an unlimited supply of SVO (Straight Vege Oil). However for SVO to match the lubricosity of Diesel it must be heated to 180degC. Coolant run heat exchangers would only reach about 80degC on a Tdi.

Apparently SVO is fine on older Mercs and old technology stuff, but not recommended for high speed turbo diesels.

At this stage I'm not prepared to risk early fuel pump failure for a short term monetary gain. But there's more to learn about the subject than I know, so I'm happy to be corrected.

I did it as an experiment for about 2 months on kermit which while admitedly not a tdi is mechanically close enough to be acceptable for comparison.

I didnt even have a dual tank setup up there and while a bit piggish to get started once going it was all good.

I did have "heater" wires run around the bits that I wanted to warm up and all I did in terms of treatment was to filter it hot as it was coming out of the vat and then leave it for a week in a 60l drum that was painted black with a small fan on top of it to suck the moisture out of the drum.

Starting was just a case of going downstairs 20 minutes before I wanted to leave turning the heater wires on and then having breakky, a coffee making a roady and then heading down to glowngo. by the time Id idled out the dive, shut the gate and eased it to the end of the road (about 300m) it was running sweet and was ready for full noise which given it was a 2.25 NA diesel was about as loud as a mouse farting.

I had also made a vauge attempt at keeping the fuel warm by sort of inuslating the tank and routing the return line via a small tube wrapped around the exhuast pipe.

Have a look at the SVO section on this site Bio Fuels Forums - Powered by vBulletin These blokes are very well informed (some through years of experience) and will be able to answer your questions. It is also worth looking here Vegie Cars - VegieCars, Chip Oil, Veggie Cars, WVO, SVO, UCO, Veggie Oil, Carbon Cops, Biodiesel, Biofuel (worth purchasing the booklet) and here Welcome to Snotta.com There are companies in Europe that sell conversion kits for brand new "modern tdi" vehicles as well as other current model trucks and commercial vehicles if you search for them. The best thing to do, is not listen to opinions and do the research yourself, there is plenty of info out there. I plan to convert my 300tdi later this year and don't expect any problems given the information I have. It is all about the preparation.

Dave your not building my confidence in my soon to be rebuilt 2.25 Diesel going into my 73 seriesIII 109 with statements like, Quote: "and was ready for full noise which given it was a 2.25 NA diesel was about as loud as a mouse farting".
Love it, you really have a way with words, Regards Frank.
