Help me sort my combo

It doesn’t sound like you drive your car very much, so I’d say once a year, or whatever you’re comfortable with for an oil change interval(2500-3000 miles, etc)........ whichever comes first.

The multiple short trips without really giving the oil a chance to get up to full operating temps for long enough to burn off the water/condensation is what I feel is the main factor in changing it every year, even if you’ve only driven the car a few hundred miles.
