... Slowly warming here in North Central Wisc, now running into the 50's & they even say the 60's Wend 
& Thurs. Getting closer anyhow, it is still early April ,& usually never gets consistintly nice until May, & then 
it is SUPER nice up here until October when it starts to cool down.

Where in Wisconsin? I'm in Hubertus / Richfield. I relocated from South Eastern Michigan here to the land of two seasons; Winter and July

. I haven't figured out where Kurts lives yet.

If its fifty and not raining (or snowing) the top is down

. I hope to see you on the road.

Oh, sorry for the thread jack; I have never gotten the blue smoke; not on the '08 or the '05.

Stay safe...

Re: Oil smoke on cold start

Tomahawk & winters a bit long but I love it up here, been all over in the winter, Florida, Arkansas, Arizona, Palm Springs, California all ok but their summers SUCK!!!!, & all that sand & NO rivers or Green, could not accept that as I do a lot of boating. Crossfire sleeps all winter, get enough top down time in the summer up here, that is why my 06 has only 7000 miles. should last me MANY years of fun yet, & my rear window is not falling out from the 120 temps down south!!. Anyhew, different strokes, for different folks, not knocking any place, just enjoy where I am.

Re: Oil smoke on cold start

Smoke on start up is usuallly valve stem seals and smoke when you punch it is usually rings. One problem with new engines is acutaully the synthetic oil. It takes a lot longer for the rings to seat becuase the oil is really too good. My brand new Mini Cooper S did the same thing so what I did is what most engine builders recommend for a new engine and that is to use non synthethic until everything is seated and sealed (no smoke) and then swithch to synthetic. My Cooper stopped smoking in about 500 miles while many guys I knew were still smoking at 5,000 miles.

I am guessing it has something to do with internals not getting up to temperature and expanding - so tolerances are on the loose side and allow a very small amount of out to pass in to the cylinders.
Again this is such a small puff and only happens as described above. I am guessing it is due in part to synthetic oil and engine materials.
I do not start and stop the engine like this too often, so it is not a big issue.
Let us know what you find.

My experience exactly. The ONLY time I see this is under this specific set of circumstances, but I very rarely do that, so I very rarely see this happen.
