Hi..

I own 2005 Honda Jazz mileage 28.000 KM. In the morning during engine warm up, white smoke comes from the exhaust pipe and soon dissapear several minutes after reaching optimum temp. (engine temp. light goes off). The white smoke smell rather like gasoline. Is this normal? Can anyone explain what causing this to happen?

Thank you...

 

It is steam from condensed moisture that forms as the metal of your exhaust system cools down in cold, damp weather.

 

Burnt gasoline is usually seen as black/grey smoke. Oil burning would be seen as white smoke.
I tend to agree with manxman. But if you have concerns, keep an eye on your oil level.

 

Have to disagree with your here- Oil= blue smoke, fuel= black smoke, white= not smoke but steam. Has been that way for 100 years, but I am willing to grant that catalytic converters may have the effect of minor changes on these visual symptoms. Regardless, white is steam.

 

oil = blue
gaz = black
prestone = white
condensation = what you got... white

 

Looks like I have a French Canadian twin!

 

yup, don't worry unless the smoke is blue or black. and it goes away after warm up too so you're fine.

 

It's probably water vapor, since water and carbon dioxide are by far the two biggest byproducts of combustion. It smells like gas simply because the cat hasn't warmed up yet and therefore isn't working at it's ideal temperature. So what you're probably seeing is simply steam, as noted above. If it really is white "smoke", and is always there, it would suggest that you're buring coolant because of a head gasket or other problem, but that is highly unlikely based on what you've told us.

 

If you havent noticed every car does this in the winter. its 100% normal. I love the way it looks coming out of my dual pipe megan exhaust lol. I know im weird.

PLUS 1 on that

 

Just water buddy

 

water/steam condensation from heat engine to the cold..should be normal
