I would submit to you it depends on the
size of the cloud at startup.
Used to get a
small puff that 'lasted a few seconds' after I started the car in the morning and concluded the following:
When I let the car "idle down" for 30-60 seconds prior to turning the key off the night before, it would smoke the next morning upon startup.
Once I showed a little "tough love" and just turned the key off, not letting it "idle down", it seems to cloud up less, if at all, at startup. Coincidence?
Your actual results may vary.
