Gday folks

I am a newbie to this biodiesel and every piece of info I get I cherish

I have been reading and searching for days and cannot find any info on what would happen if a small amount of used engine oil was mixed with WVO before making biodiesel

the story

I acquired about 100lt of WVO and I put it in an old 200lt drum that was used for storage of waste engine oil (drum was well drained but there could have been up to a cup? of oil stuck to the inside of the drum) the black engine oil has coloured the WVO a fair bit

so will the process of turning it into biodiesel affect the reaction?

thanks for any input

on other forums there are reports of people running 50percent used engine oil in their diesels blended with vegetabel oil or bio. I am sure the little bit in your oil won't hurt the oil at all or make it react any different.

Hi,

I'd try doing a small 1 litre batch first. I have no idea what it would do for your titration results though. If you get a fair titration, try it. If it produces good biodiesel, scale it up to whatever.

Good luck, Chris

thanks for the info

I will add another 100lt to it so it will be well diluted, i was just unsure about the reation

I will go and do a test batch first before I add the 100lt extra

Murf,
From my research, it will not have any impact on the quality of the biodiesel but it may turn out a very dark biodiesel if the drum contained used diesel engine oil.

Tony
