    Full flow engine oil filters have 50% particle removal at 25-50 microns.

    Fuel filters have 50% particle removal at 5-15 microns

    Soot is << 1 micron.

    So your fuel filter won't remove any significant amount of soot.

    This engine runs seems to just fine on its own crude that it pumps out of the ground, does not appear to be any filtration at all before the lift pump.





    but seems a greener way of doing things, no refinery waste or transportation costs.

    Many Australian crudes are very light - e.g. gippsland crude has about the same viscosity and density as diesel, and is a pale straw colour. Also, importantly, crude is not full of soot particles.

    Many overseas crudes look like mud.

    I bet you would be wrong on that one.

    Soot is << 1 micron. shouldnt cause any problems them if your filter lets through contaminates that are 5-15 microns?

    How hard is it to explain these concepts???

    Soot causes wear. Soot is not a normal component of fuel, so fuel filters aren't designed to remove it. Removing particles of that size from fuel is very hard.

    How hard is it to understand that if the fuel filter lets it through it isnt big enough to be a problem?

    Soot = carbon. Carbon in a lubricant not an abrasive.

    I posted a Society of Automotive engineers paper on "soot induced wear" on the previous page, and you reply with ehow dribble???

    Soot = carbon. Carbon in a lubricant not an abrasive. you disagree?

    Heres an idea, dont use diluted used diesel oil in ya fuel tank.

    You're arguing with a guy who is a specialist in this field.

    Carbon is also:
    A diamond
    A conductor
    A grinding medium

    EGR systems introduce Soot (Carbon) back into the intake and cause wear and damage.

    Graphite has its own name as its a particular version of the material and has differing properties.

    Kish is also Carbon.


    In a similar vein, Silica is Sand.
    It's abrasive.(blasting)
    When melted its smooth (glass)
    When it's liquid it's corrosive to refractory.

    Many compounds display differing behaviours and can't be simply described.


    Some trucks did inject fine quantities of oil into the engine - whilst replacing from a fresh oil tank. I'm not sure if its still a compliant method in new trucks.
    The volume introduced was very controlled.

    Carbon as a fuel too ??

    Dad made a gas producer that burned wood to make fuel for his old Buick Straight 8 , when petrol rationing was on during the 50's .
    cant have been too healthy for the engine with all that soot pumping thru , probably fail todays emmission test I guess.

    I still bet modern greenies would be happy running their Peugot 504's on one of these, despite global warming.
