Hi, I own a '16 XT with about 20K km on it. On some cold starts, I notice a bit of white smoke that lasts a few seconds. I park in an inclined driveway with the front lower than the rear. I owned a few 2.0l Turbos (Saab, etc) and a few boxers (VW, Alfa Romeo, BMW bike). In any case, turbos some time tend to deposit a bit of oil in the intercooler, boxers tend to cumulate some oil in the cylinders... but this is a new car...so not sure if I should be concerned. The only other time I notice what seems to be white smoke is upon very hard accelerations to pass (agressive) 90km-h to 120 @ close to full boost.

This cold start smoke occurs on occasion, not on every cold start, and in the summer (winter = hard to tell).

I check my oil regularly, all good. I always let the turbo warm up and cool down. Change the oil avery 6-8K (km)... not that this should change anything this early in its life.

Anyhow, any thoughts appreciated.

Regards,
DJT.

Try a warm start( just after a long drive) to see if it still exhibits the same.

No?,,, then it's just condensation- byproduct of combustion (and a cold overniight sit).

Just about ANY car will do this to the point of water dribbling out of the pipe.(not so much in Phoenix...)

Montreal is another matter.

Hi, It never does it on a warm start. It's definitely oil (not condensation). White smoke cloud that floats around for a while. I have my 30K Km service comping up so will converse with the dealer on the issue.

I'd be curious to know as well as I've had this startup smoke a couple times now on my '17 XT with about 14k km on it.

Like you, it's on occasion, once or twice while the Forester was parked in the garage.

Well, had the 30K maintenance done last week. They inspected the charge-pipe (not clear on which one this refers to - pre or post turbo) of the turbo to check for oil deposit that would result from a suspected blow-by but said they found nothing. They suggested we inspect further if this persists...which it clearly will. In that case, I will need to leave them the car to reproduce the issue.. but not sure what that would do for them. I did, however, notice a small amount of smoke on startup the morning of my visit to the dealer after the car had been parked overnight on a FLAT surface. This eliminates the link to parking in a slope. I still have the impression that this happens mostly if the car was driven hard the day before and parked overnight. Again, NEVER happened on warm start. A good friend of mined mentioned having the same thing once in a while; even black smoke on occasion on his older XT, but never investigated further as it was a lease.

Quick update: did not see the white smoke for over a year now (winter + summer). I have been making sure that the dealer does not overfill the oil.. might be the reason behind it...taking care of the oil changes myself from now... around 60K km now.
