What do you mean by wasting oil, is the oil disappearing and you don't know where its going or is it fouling up so quickly you feel you have to change it to keep from damaging the engine?

if your oil is turning black, it's doing its job. your oil will be black after one heat cycle. your oil is there to lubricate and there are detergents in there to clean and isolate particles from bearings and oil passages. as long as you change your oil every 3-5k with a filter, you're doing good. why did you pull it after only 2 days, there's your oil wasting...

could be a faulty pcv valve... only like a 5 dollar part so try and see if that fixes the oil from vanishing... when my 5.4 had a bad pcv valve we would lose oil everytime we ran it and there wasn't a sign of smoke from that truck at all... almost lost that engine over a 5 dollar part..

that's an easy one to figure out, you can put your finger to it and feel it working. it shouldn't burn that much oil though, and when it does it runs bad but the oil doesn't go back into the crankcase. what happenend more than likely is that the po used a conventional oil (pennzoil, quaker state) and the blackness is sludge. the filter will take all of the harmful particles out of your oil.
