   How many owners manuals do NOT specify the oil change volume both with the   
   oil filter also being changed and the oil change volume without the filter?   
      
   How many owners manuals do NOT specify different maintenance intervals based   
   on the type of service (for example the severity of driving conditions such   
   as "dusty conditions" and/or the total number of accumulated time and/or   
   total number of accumulated miles)?   
      
   I have my 1990 Infiniti Q45 service manual in my hands at this very moment.   
      
   Page MA-5 shows a one to one oil change and filter interval while the very   
   next page MA-6 shows an "R" (for replace) on the oil filter every other oil   
   change and the air filter gets its "R" every fourth oil change interval   
   (the intervals being tabled under distance or time "whichever comes first").   
      
   I can check others but you must have seen similar in maintenance schedules.
