WHITE smoke? Or BLUE smoke? White smoke is usually caused by burning antifreeze (possible blown head gasket). Engine oil burning causes a bluish colored smoke.
Changing the oil two months ago means absolutely nothing to me. I have customers that travel 6000 miles or more in a month. Oil consumption is measured in volume over miles, not volume over months. It is normal for most 4 cylinder engines to use a little less than 1/2 quart in 1000 miles (even more than that for 6 cylinder and 8 cylinder engines).
White smoke always means that oil is getting into the cylinder. This will make the car sputter. You have to find out why the oil is getting in there. It needs to go to a mechanic because it could be any number of reasons why the oil is getting in.
YOU NEED TO REPLACE DRIVE BELT BEFORE IT BREAKS. IF CAR SMOKES HEAVY WHITE YOU A HEAD GASKET LEAK.IF CAR SMOKES BLUE SMOKE ALL THE TIME YOU HAVE WORN OUT PISTON RINGS OR VALVE GUIDE AND VALVE SEALS.
If the car is smoking through the muffler then its burning the oil if not, check for a loose engine filter or leaky oil pressure sensor that leaks only when the car is running.
possibly the pcv but check if your cars exhaust smoke is blueish or white in color if it does and your car doesnt have an oil leak then sure its burning engine oil along with fuel, the piston rings is defective, since you replaced engine oil the additive that the owner has put with the oil to prevent blowby is gone thats why it starts burning oil.....
Does the car emit blue smoke from the exhaust when driving? If so, either the piston rings or valve seals could be bad (expensive repair). The PCV valve could also be bad. The last reason (but no blue smoke) might be a physical oil leak due to a loose oil filter, drain plug, leaking oil pressure sensor, or worn crankshaft seal. Good luck!

In any case to finish the 2nd suggestion. You may want to discuss this issue (smoke and oil consumption) with your dealer. Cite a Lexus Technical Service Bulletin specifically addressing this issue "Excessive oil consumption caused by sludge buildup on the cylinder heads. Company is extending warranty. (1997-2001)".
