White Smoke From the Engine then starts

[Porschev]

HI guys
I experienced this for first time :

Taken from 986faq.com

"Diagnostic: White smoke comes from tailpipe when the engine is started.

Cause: Oil residue under the pistons heads.

Details: The Boxster engine uses a flat six cylinder design. Because of this construction, oil residue remains under the piston heads and burns off at every start up. This can produce a white puff of smoke. It should only lasts a few seconds. This is normal, and no correction is necessary."

Question may be i need to take some oil off, i changed the oil recently and maybe put more than nessesary?

Thank you all
