Saab95 smoking problem
 

I was wondering if one of you Saab Gods could give me a hand.

I have a 1999 Saab 95 SE 4cyl. It is billowing HUGE white clouds of smoke from the exhaust. It does not smell like coolant and all fluid levels are fine. It also does not overheat so I am pretty hesitant to say it would be a head gasket (though I could be wrong, that happened once :p). When it began it was only on start up and gradually it has gotten worse. I don't drive it much so I figured I would have some time to get it fixed. Now, it's a lot of white pillowy smoke - a lot! Thanks for any help!!

P.S I didn't know forums like this existed! I'd like to spend a little time looking around:) Nice to meet everyone!

Are you positive that all fluid levels are ok? Because if there's no loss of coolant or oil (which doesn't take much to create huge clouds of smoke) than the only other possibility is water in the gas tank (aka crappy gas from an old gas station)
