My friends and I have been noticing a white haze coming out of my tail pipe of my ecoboost when I get on it and start up. I would understand if it was cold and it was blowing smoke but why when its hot? I'm kind of concerned.

My engine did it last night and the past few days bits its been about 60 degrees its jus the engine warming up

If it's not burning oil or coolant you're fine.

Blue = smoke (oil)
White = vapor (water vapor condensing as it hits cool air)

You'll see vapor on cool/cold mornings, or if you have condensation in your exhaust system somewhere. It should go away after everything warms up.

If you are seeing blue smoke (and the smell of oil)...then it's not good.

I was scared it was my turbo. I've heard that the ecoboost turbo will lag, or stop working and make your engine smoke.

If you blow a turbo you'll know it. It's not like it just stops spinning and sits there quietly.

Lol I know that...

My friend noticed my truck puffs out alittle black smoke after I get on it and let off. But it doesn't smoke at all any other time. Any ideas?

As the temperatures come down it will be more noticeable.

It has been mentioned the Eco uses quite a bit more fuel during start up, so is a mix of condensation and really hot exhaust hitting the outside.

Fuel. Its direct injected. What your seeing at wot is normal.
