You have proved what the issue is right there. Our spec is "less than .058 amp" but most base/SE models seem to run .015 to .020, mine varies from .016 to .019; my limiteds ran .040-.055.
At .020 or less, you can go 3-6 weeks without starting the car. I start mine every three weeks anyway. I do not use battery tenders or chargers.
