[Jim Brierley]

There was a recent article in our paper stating that oil is usually changed too often, I agree. I change my wife's Prius about every 6500, non-synthetic 5-40 (?). It now has 133,000 on it. I change my '99 F-250 diesel every 5,000 and the filter every-other change. One time I was traveling and the Ford went over 6,000, I sent in a sample and the report said everything fine, make no change in procedure. It now has 196,000. Change less, save importing, your engine will do just fine!
