Was browsin thru the net and saw an article on black diesel. They use old oils...motor,gear,hydraulic to recycle filter and burn for fuel. Anyone do this or have opinions? Safety warnings or anything?

 

i run a lot of that stuff, but my rigs are mechanical, the third gens have a completely different fuel system, we have been playing with it a little, but we arnt using very much, do to the pressures and tolorences on the common rail, but my 12 valves i run up to a 90% mix of waste oil to 10% diesel with no issues

 

A 12 valve will burn anything that is combustible and liquid. I would not experiment with waste oils in my common rail engine. The injectors are VERY picky about fuel.

 

Dodgetrucker75 -- Do you filter your drain oil or just go from crankcase to to tank?? thanks

 

You would have to filter it. otherwise you can clog up up your filters and injectors in a hurry

 

if i get it from an engine and use a clean pan, i just pour it straight in the tank, others like hydraulic oil i filter because it can have a lot of nasty stuff in it, i have a setup with a pump and a 2 micron filter/water seperator, i run it through, and also i run the same filter on the truck ( i think stock is 10 micron) along with a fuel pressure gauge, to save money on filter changes... just wait till the pressure just starts to drop then change, i havent changed one in over a year and a half, with running all this oil, and on a side note, they claim that anything that can make it through the stock filter, the pump /injectors can handel it.
