Hello,

Usually white smoke is indicative of coolant being introduced into the combustion chamber and being burnt in the combustion process of the engine. It is usually accompanied by a sweet smell and the need to regularly add coolant. This is usually caused by a blown head gasket.
The other problem, having to regularly add oil, could be an oil leak somewhere. I have included a few links for you to go to down below.

Please go through these guides and get back to us with what you are able to find out, please.
