You may have a blown head gasket. The white smoke may actually be steam from coolant leaking into the combustion chambers. If your car is using a lot of water, this would back up the blown head gasket theory.

White smoke is coolant and black smoke is oil. I agree that this is likely a problem with your head gasket.

normally when the engine emits bluish white smoke, the engine oil mixes up with the gasoline in the combustion chamber-as a result of loose compression. White smoke - Water in the exhaust, head gasket gone? check for emulsion on filler cap and do a compression test. Blue smoke - burning oil, check valve stem oil seals, valve guide clearances or piston rings Black smoke - Fuel mixture too rich, go to a garage and have it tuned.

What would happen if I have a 4 cycle engine with oil and gas mix?

I don't think the oil/gas mix will harm the engine, but the engine will probably emit greyish-blue smoke until the oil/gas is burnt off. Also, the spark plug will probably foul due to the oil, and cause the engine to burn rich and emit black smoke. The engine will probably run rough until all the oil/gas is burnt and you will have to remove and clean the spark plug often. Save yourself the "headache" and drain the oil/gas from the fuel tank.
