You need to be able to state how much oil was consumed in a given number of miles (1,000). So write down the mileage at which you topped off the oil to H, then watch the oil level until it goes down to, say, the mid-point (or even the L point) on the dipstick, then determine how much oil it takes to top it off back to H and record the odometer reading when you do top it off. Then you'll know what the rate of consumption is, and that is what will tell you if it meets or exceeds Nissan's "excessive" amount.
