Oh, tales of oil woe... I bought a 1993 Dodge Duster (same as a Sundance but with a V6 engine) with 160k miles off my stepdad, who was a mechanic and very meticulous about maintenance, so I knew it still had a lot of miles to go. Drove it 100k more miles (original engine), being sure to keep up on oil changes. Didn't always get to it at 3k miles, but never went past 4k. Then sold it to a friend and told him he better keep up on the oil changes since it was a Dodge w/ 260k miles, which I didn't even know was possible. He drove it 20k miles, never changing the oil, before it started knocking really bad and he sold it to a junk yard. Was sad to watch happen, that car treated me really well at a time I had no money, and I wanted to see it make it to 300k.
