Just curious what oil consumption others have experienced with the 1991 350 SDL(SD). My previous SD which had around 90,000 when purchased seemed to use about the same amount as my current SDL. They both usually would wind up about halfway between the min and max mark on the dip stick at around 2500 to 3000 miles on the change. With 75+ MPH interstate driving during the latter stage it seemed to use more faster. Just wondering what others have experienced?
Thanks,
Frank
