Wvo and svo

[Poodle]

Using waste is well worth it if you use it accordingly, rather than just assuming it'll be the same as using diesel. Know a couple of lads at work that pick it up for free and tend to get a good 180L of fuel out of a 205L drum or wvo. They both use old immersion heater tanks (not actually heating, just because they're a good size and shape with outlets at useful points lol) with a serviceable/replaceable filter system on both the tank feed and outlet.
