   That's a good point.  I used to change both oil and filter yearly but   
   stopped changing the oil yearly since the oil was always fairly clean.   
   But with the wear miles getting up there there will be more combustion   
   products in the oil now.  I travel quite a bit for my employer but   
   usually rent a car locally or fly somewhere and then rent.
