Oil change

lachap55

I have 2010 370z touring sport pk. I have receive about 7-10 oil changes from the nissan dealership since i bought the car in 8/22/2010. When i check the oil after the oil changes the oil is always at the H mark....everytime . This year i drove to fl.(800 miles) and notice the oil had drop a little to the top hole on the dip stick. since the oil was always at the H mark i added under 1/4 qts of oil to get it back to the H mark. CAR HAD COOL DOWN FOR HOURS, before i check the dip stick each time. I have never own a car that had any consumption problems so i took it back to the dealership. I get my ticket back and the maintance man wrote a comment, " oil a little high".I will take the car back in 8/8/13(next oil change)to see where the dip stick is at and question why do you put oil in to the H mark then? DUMMY ALERT; I always thought the H mark was were the oil was suppose to be; not for, your oil is at the HIGH mark.
