OT mechanics- smoke coming out of exhaust

2019 Infiniti Q50 90K miles
I've noticed the last two days that I had smoke coming out of the exhaust. It wasn't much, and it doesn't do it all of the time. It happened while I was sitting in carpool so car was idling, and was probably the only reason I noticed it. Stepped out the first time and smelled like burned oil, I looked at the exhaust pipe and it looks like it may be burning oil as well. I'm actually about to take it to get the oil changed at an oil chance place, should I change that and take it to Infiniti?
It is turbocharged, but I haven't noticed anything that would make me think it's turbo related. Haven't noticed that I've been missing oil when I've been checking it.
ETA: edited to clarify- white smoke

What color is the smoke ? What’s in the exhaust when you pass your fingers n there ?
White smoke is vapor or oil. Black smoke is fuel. Coming out of an exhaust.

You actually may have. Any of the piping from the pressure side of the turbo to the throttle body can be pulled and checked for presence of oil. It should be squeaky clean and dry. If not… time for an upgrade.

It's either oil or water/coolant. Blue smoke = oil. White smoke = water/coolant.
Both are bad.
Check levels on both to diagnose it yourself. Top it off, sell it to some poor bastard, and get a new vehicle.

2011 Tundra, 200,000 miles, never had a problem.

I had a 2015 Nissan Maxima that did the same damn thing. Would do it maybe once every 3-4 months. Always checked the oil and wasn't losing any. I took it to three different mechanics and they could never get it to duplicate. That went on for about 4-5 years before I traded it in. No other issues so I don't know...

White smoke should mean coolant. Head gasket probably bad.
Could also be condensation but most likely not.
IMO.

Pull the oil dipstick and look at the oil. Does it look like chocolate milk? If so you have coolant leaking internally in the oil system. Usually a head or intake manifold gasket.

I honestly wouldn’t be overly concerned about it. Just keep an eye on the coolant level as well as the oil level and go on about your life.

90,000 miles, time for new spark plugs anyway so change them, do an oil change, replace air filter and do a coolant flush. All regular maintenance items that should be done anyway. Then keep an eye on it.
