A common and use-able idea Back in The Day. The extra tank was rock-diesel, and a flow switching manifold so that starting and end of journey was fueled by Diesel, and the OIL tank was water-warmed which obviously, was used for bulk of journey.

Idea was to start on Diesel, warm up engine which warmed - and thinned - the veg oil, and again to flush out the I-Pump before shut down.

Straight Vegg Oil could be used via extensive filtering either/both ON the vehicle or up. the backyard. Most economical method. Also -depending on the oil source, heating HOT with water... stirring...then settling takes out a lot of rubbish. Then fine sock filters. Good also for prepping the oil for making biodiesel as it takes out floaties, making the split glycerine suitable for fine soap making. [bigsmile1]

I can see the value in using recycled oils But burning perfectly good food just to run a jet or car makes little sense to me.

Would the jets run using an air fryer instead. Works at home. Chips just as good without the oil[bigwhistle]
