My car is loosing oil slowly. I checked under the car, replaced the spark plugs and I cannot find where the oil is going. There is no smell of fumes; only after about two months or so the dip stick gets below the first hole on the dipstick. Any suggestions?

How close in mileage are you to oil change. When you pulled plugs what did they look like.

If there's no leak externally-check the radiator for oil, not there -could be burning in the combustion chamber.

You can monitor consumption, the acceptable rate is around 1 quart in 2000 miles. To get a better grasp on if it is irregular, start a consumption test by placing it at a known level, and checking it periodically, say every 1000 miles. Consumption can vary with driving habits.
