   Different situation but when I was driving the standard was 12,000 miles   
   or about once a month. At 10 gallons or Rotella and two or three   
   filters, that adds up.   
      
   When the older trucks were being replaced with Volvo Whites with the   
   Detroit 60 engines, the shop foreman started a testing protocol.The   
   tests showed no significant degradation at 20,000 miles but that became   
   the new standard. When I asked him his reply was the oil had to be   
   changed sometime and 20,000 seemed like a reasonable target.   
      
   The Detroit 60's were game changers. A lot of them were hitting a   
   million miles without an in-frame rebuild. Previously most big diesels   
   were tired at about 700,000.
