Wvo and svo

[Ben Jay]

Depends on a number of factors. Collecting 20-30L at a time is very time consuming for a start, better to try and collect in bulk.

The quality of the oil will dictate how much of your time is spent making it usable, and how much fuel you get out at the end. Crap oil = lots of time spent for not much fuel.

If you go WVO spend the money on a proper setup. Fannying around with sock filters and drums is the cheap way of doing it, but you end up with everything covered in grease and it takes ages. You might spend £100 - £150 but that will be paid for after 2 tanks, it will save you a lot of time and it will make life a whole lot more pleasant.

I highly recommend you get some misfuel. Blend it in 20% and gravity will do all of the work in 24 hours. Drain off the rubbish and the rest will fly through a 1 micron filter. A single 10" filter element does me about 1500 litres of oil (it gets changed once a year). It's also 20% of your fuel that you don't have to pay for (indeed you might consider blending even on SVO).

About an hour of my time results in 150 litres of usable fuel costing 18ppl, so no brainer for me. Bear in mind that the price of SVO is volatile, it wasn't that long ago it was more expensive than derv.

You for any pics of your set up? Looking to build a filter system
