Undoubtedly. But think of the time, money, and waste oil you could have saved by following a more reasonable change interval.

Your way (Grandpa did it, and the corner quick-lube guys recommend it): 63 oil changes, 79 gallons of used oil, and assuming 30 minutes/change, almost 32 hours.

My way (factory recommended service interval): 38 oil changes, 48 gallons, and 19 hours, and likely with results just as good (assuming you don't actually need the severe duty maintenance schedule that you implemented.)

Switching to an extended-drain oil may or may not save you money, depending on how much you drive in a year. It's more expensive per oil change, but can save you money in the long run.
