That can be caused on most vehicles by one of two potential problems: 1. cylinder "washdown", in which one or more injector leaks a little, dropping raw fuel into the cylinder. The fuel picks dilutes the oil that normally resides on the cylinder walls and around the piston and rings. Next time the engine starts, the oil is burned along with the excess fuel. The condition can cause a little extra cylinder wear whenever the engine starts, and should be repaired to prevent future problems. 2. Valve guide oil leaking, usually caused by hardened valve guide seals leaking a small amount of oil down the intake valve stem and it gets into the fuel mix. Typically, leaking valve seals will burn whenever you step on the accellerator after slowing down, or going down a hill with your foot off the accellerator. It usually indicates a worn valve guide AND hardened/damaged valve guide seal.

White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.
