Even with a brand-new vehicle, it is not unheard-of for oil to be consumed at the rate of 1 qt per 1,000 miles. For a vehicle with 66k miles on the odometer, consuming 1 qt every 2k miles is certainly not unreasonable.
As was already suggested, the biggest problem in this scenario is a vehicle owner who apparently doesn’t bother to check the oil dipstick on a regular basis, and who only seeks help when his/her engine begins to make strange noises.
If the OP doesn’t know how to check his/her dipstick, then enlisting the help of a knowledgeable friend would be a good idea. A car owner who wants to get the most miles and years out of his vehicle–with minimal repair costs–will check the oil of his/her vehicle at least every couple of weeks, with the object of the game to make sure that the level never falls more than 1 qt below the “full” mark on the dipstick. Personally, I like to replenish the oil once the level has fallen by 1/2 qt.
