(x5 03 3.0i) white smoke came out exhausts upon startup!!!!!!!

[Blue Mountain Raider]

so this morning i started up the x (90k kms so far) in garage, as soon as engine fired up it sounded different then i went out and noticed white smoke (strong gas smell) was coming out.

i shut it off and start up again, same thing happened. on the thrid start up, the engine sounded fine, and the white smoke stopped after a few seconds.

i drove the car about 20km and everything was fine. does anyone know what caused to white smoke? btw no check engine light came on.

not sure if those two events are related:
(1) i changed oil a few days ago to mobil 1 5w30, before that it was castrol syntec 0w30.

(2) about 40 hrs ago at night, i started the car to park inside garages, the car was on for like 30 secs. hasnt started since until this morning.

im kinda worried now. any ideas? thnx
