3mo/3k miles is based on what Auto Manufacturers call severe conditions or
every day use if you lived in California. It would be a waste to change the
oil at 600 miles. I'd agree with Frank, switch to synthetic and change your
oil less often. If you're worried about voiding your warranty, you could
change every 6 months, but check the condition of the oil and other fluids
at least once a month.
