Mine does it about every other start up. A big blue cloud of smoke engulfs the whole back end of the car. I took it to the dealer while the local rep. was there and he said "Smoking from the engine is normal and not excessive, until it uses one quart for every 900 miles you drive". Mine uses roughly a 1/2 quart under "heavy foot" driving every 2500 miles. The mechanics later told me "You bought a Ford....that is to be expected and it is completely normal". My dealer offered no extended warranty or apologize for the situation or offer any help.
I have not had near the good experience at my dealer as I have seen some people on here have at theirs. Everyone acts like they don't know anything, except if you wanted to know how to cook up some possum, that they could handle. It is scary!

I have actually considered driving to Atlanta, 200 miles away, to see the dealer there! It is that bad.
