I have a 2008 BMW 750Li with 88,000 miles. Other than the common minor / slow coolant leak (yet to fix) it has been a fabulous car.
Two days ago I noticed after a restart with the engine still warm, it was burning visible, white colored exhaust.
I had the oil changed and it still did the same today. I typically use shell V- power gas.
Any advice to treat this? Fuel treatment additive perhaps?
Are you sure the white colored exhaust smoke is not coolant?
It's coming from the exhaust.
