waste used oil as alterantive diesel fuel

Did it for years, only thing is to keep water and solids out of it.

I pumped it thru two, three micron filters. 70/30 diesel to waste mix in the winter and 50/50 in the summer. Problem is if the revenuers dip your tanks they could get you for it using non taxed fuel.

 

I would collect and/or make all you can and use it heavy in warmer months and then accumulate it in the colder months for the coming warmer seasons.

 

Had a friend that used it for a long time. Not sure why he stopped, except hard to keep up with production for all his equipment. Never ran it in his semi though. Burned just fine!

 

What do you do for fuel tax though? I have thought of making biodiesel and running it blended 50/50 with diesel. Wouldnt the revenuers pick up on the fact that you are getting double the fuel mileage you actually are?

 

They could catch you, unless your new green aero dynamic whatcha ma call it fuel saver got you more mpg

 

Easy way to check the mix is to do a simple cloud test of your mixture, start out with a 50/50 blend of your home fuel and wait for a average cold day in your hauling area. You want the fuel to not cloud on the coldest day, if the fuel clouds reduce the bio and add more diesel.

 

Just to be clear - are we talking about used motor oil filtered, or actually refined motor oil? I wouldn't even dream of putting the first in my diesel. Even small amounts.

 

I've ran a car on both veggie oil and waste veggie oil, works a dream, waste veggie oil was better,a tablespoon of mentholated spirits into every 5 gallons and it ran like a clock except for the smell you get from chip shops off it, we used run trucks on agricultural diesel , we used use split tanks, the part of the tank under the filler cap was regular diesel (for when u get dipped) the rest was ag diesel filled through the appeture for the pipes and diesel gauge fitting, you could try something like that?
