My 2006 Ford Fusion (4 cylinder, manual transmission) is using a lot of oil.
1 qt every 300 miles. No smoke, no oil spots under the car on the garage floor.
Where could the oil be going?
If you don't have oil in your coolant, the only option for the oil to go would be is through the exhaust and out, make sure the pcv valve is not bad not stuck closed not shorted out, the oil in the exhaust might not be noticeable.
