I love this post! I've been doing the 3000 mile oil changes since I started driving and never had an engine give me any problems. I have three close friends who all own diffrent cars and are 2008 or newer, two are doing oil changes at 7500 with an new filter every other change and the other who owns a VW Jetta goes 10,000 per oil change. The Jetta has 60,000 miles on it and is ready for a new engine. The other two have a bit more miles but they're not too far behind him in needing either a rebuild or new engine. My wifes Hyundai (05 Santa Fe) has 120,000 miles on it and it runs like a swiss watch, it does not use or burn any oil. I find it funny how you can buy into the fact that number one dirty oil is better for the car and two so is a dirty filter.
