Agreed. Scared myself when I first bought the car with a low reading, but didnt realize how much thin 0w20 was and that incline/decline makes a big difference. Going back to my buddies shop tomorrow night to change the oil and will be able to see a more accurate measurment from the same spot. I was also considering capturing and measuring the used oil that comes out, but am not sure how accurate this will be. I know not all of the oil comes out during an oil change, and I have a fumoto which will leave a little oil in the pan since the threads protrude into the oil pan.
