With the help of the priceless knowledge that i have acquired,the problem indicates towards burning coolant(yes, technically it's boiling, not burning).You need to give GOOD DETAILS first. Does it ALWAYS burn white? Just at startup? Only when hot?
But after reading your complete statement,doubts goes towards overfilling the oil too, OVERFILLING THE OIL will produce this white burned smoke too. It will also usually go away after some driving.Overfilling,at first a lot of smoke, then only at heavy acceleration when demand is high.
check your fluid levels (OIL,coolant/water ) of course, whatever is low is what you are burning.
Mostly it means that you are burning antifreeze when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber causing white smoke.
Has your car severely overheated recently? you probably have a blown head gasket,what type of smell you observe?
Oil of any automotive type burns blue.....too much fuel issues burn black not enough fuel issues burn grey.
