I started my car today and notice some white smoke comming from the muffler and under heavy throttle I get a little smoke too! Is that normal????

 

White, when cold is nothing to worry about. You have moisture/water in your exhaust, when you start it up, its being blown out of your exhaust and evaped as well. Now if it was GREY or black, then I would worry a little.

 

Well it was 93 degrees out side and the car was at normal operating temp. Is it still normal?? and the smoke kinda smelled like rich burning gas.

 

Well, it still may be ok. When the car starts up first I think it runs rich. But, it should have returmed to normal shortly thereafter since it was at normal operating temp like you said. The little bit of smoke at WOT should also be OK. That is probably the extra fuel burning off.

 

I feel a little better now!

 

its the blue smoke ya gotta hate.

 

Doesn't matter what temperature it is really outside, but how long was your car sitting for? Car was normal operating temp, I supose you just drove it before then? If so, car may have been a little rich....it will aways start up rich.

 

white smoke is burning oil and black smoke is burning engine coolant...or maybe the other way around...i just remember hearing that somewhere...tell nissan since you are probably under warranty (well more-so than i am)

 

Talk about burning oil, I changed my oil for the first time this weekend and put in the 4.25 Quart as recomended. But the thing I noticed is that I got considerably less than that when I drained the engine oil (about 3.5 quart out). Should I be worried that the engine is buring off oil??

 

nope...your engine always burns off a little oil...nothing to worry about

 

I think you may have it reversed. This is the way it goes as far as I know:

Blue Smoke : Burning Oil
Black Smoke : Burning fuel (running rich)
White smoke : Burning Coolant/water

 

Incorrect, Black smoke is oil, Grey smoke is something, but white is water.

 

Purple haze is Zex
Blue haze is NOS
I forgot what the other colors are.

 

You should be OK...you probably had some oil (at least a half quart?) left in your oil filter.

 

Dude! Have you seen one of those oil filters? I don't think it displaces half quart of oil even when it's in the box (it's kinda small).

Yeah, there's oil in the filter, but it should be no more than 1/8 of a quart.

Maybe the dealer didn't fill it all the way or something...will check back in about 5K miles

 

blue/grey is oil. black is gas. Im 100% sure of this. My friends Camaro burns them all. LOL

 

black....running rich
blue/gray....oil
white...coolant/water.
