White smoke from an exhaust When a cold engine is started, it soon begins to heat up, and a byproduct of this is water vapour. This creates condensation within the exhaust system, which then turns into steam as temperatures rise within the engine. Once a car has warmed up, this steam soon evaporates.

Is white smoke on cold start normal?
1 Answer. @thedean , Dean, 5w20 oil is fine, Some white smoke at start up from cold engine is fairly normal and will dissipate (stop) for the most part after engine and exhaust has warmed up to operating temperature.
