The argument for long oil change intervals wasn't helped much in recent years as some manufacturers, including Saab, who had specified long oil change intervals, ran into sludge problems in some engines. Those who had been changing their oil frequently did not have these problems. Others, who were doing your (and the mfr's) recommended long oil change cycle didn't fair as well and many have had to have their engines replaced. As a note, at least Saab recently came out and admitted a design flaw which allowed for this happen. As a general rule, synthetic oils will allow for longer intervals vs their non-synthetic cousins. Few will argue this point. The debate really is on precisely _how much longer_. 1000 miles? 10000 miles? More likely, somewhere in between. And of course, driving habits will affect this greatly. If the car mostly does short jaunts of less than 15-20 miles, than this will certainly affect the equation. Perhaps this is why the American market is more geared toward shorter oil change intervals (not to mention its market bias toward natural vs synthetic oil), as Americans may be more apt to use their cars even to drive just a few blocks down the street. - tex
