If you mean the smoke it's usually related to the quality of petrol
Black smoke means you're burning fuel, blue smoke, you're burning oil, white smoke, you're burning coolant.
NO
blue smoke is caused by oil burning in the igntion chamber. oil gets there thru bad oil rings on pistons,or bad valve stem seals in the head,
blue smoke can be caused by sticking valves or burnt rings
Burning of oil in cars can contribute to blue smoke from exhaust. However, it is also possible for a car to make blue smoke if a turbocharger is broken or experiencing an oil leak.
no.
burning oil
Burning oil
My understanding of exhaust smoke is that Blue is oil, Black is unburnt fuel, White is unburnt diesel on cold start. The main question would be, how much smoke and when does it do it?
Stuck or broken oil rings can cause blue smoke.
if you have blue smoke coming into the exhaust that means your piston rings are bad and are letting oil into your combustion chamber and then causing the oil to be burned with your air fuel mixture and that's why your exhaust is blue from having that burnt oil dumped out of the exhaust valve and out the exhaust
