i just checked my oil level and the oil seemed to be at the first hole or a little below. So i put 2 quarts of Castrol GTX and now when i check the oil it is really hard to see the oil level, the oil is so clear. Sometimes the oil level seems above the second hole and other times it seems exactly on the second hole. Suppose i put too much oil in my car will it do it any harm? Also does anybody have any tips for checkin the oil level. I followed the instructions in my owners manual, but as you all can see i leave the oil changing to my dealer. Thanks for any help.
