    White smoke is normally a steam/condensation issue.If it decreases as it gets hotter,then this is condensation droplets in the exhaust system being burnt off. Although in "colder" weather (.which we have had a lot of recently)the normal water droplets coming out the exhaust show up the same way.If it persists,and gets worse, then it points to a Head Gasket issue,but this would also show up in the loss of water/coolant in the system,and have the need to top up. The oil usage / burning is a seperate issue that will need to be looked at,before it starts fouling up your plugs.and other problems.

    I would of said piston rings.

    you had the head gasket tested which test?

    as far as im awair there are 2 main ones

    (1) sniffer (tests for c02 in water)
    (2) compresion tester (tests compresion)

    now i had alot of smoke out of my zafiras engine untill i replaced it. I tested it with the both tests, both came back as good so i stripped it down and found out that the piston rings were leaving streakes of oil in the bores which then was burning and causing smoke..
