You may want to consider using a 20W-50 weight oil. You will get a little more life out of it if you are thinning in after only 2,000 miles. However, if you are only using the sparingly, you may want to change it every 2,000 miles.

Off the top of my head, change the oil every 3,000 to 5,000 miles or very 6 months ,whatever happens first. Of course consult with your Tech and manual first.
