60 dollars for an oil change is insane. and i dont think you are putting enough oil in your car. i put 4 qts in my f22 and i know the h22 holds more oil. if you only put 4 qts in and then checked it without starting the car up you would probably get a full reading on the dipstick because no oil has gone into the filter yet. if you then checked it later after the car was driven you would definately get a low reading.
