Since the oil is only changed every 3000 miles cost is not really a concern..but I don't want to spend money for something I don't need.. ps.. It will use a quart or even 2 between changes...bart

That's not good. Oil has an operating temp range. It's generally accepted that 180* is minimum operating temp. Much below that, and it's not working the way it's supposed to. Unless we're talking about C*.

Maybe the second statement has something to do with the first. You're using a quart every 1,000-1,500 miles. That's a lot of oil for something used so gently.
