the main point I was trying to make with his comment is that he may be right, but only because people are going to draw out oil changes to 8, 10 12k miles. I use synthetic and still change it at 3k. as I said in my post now they've released an oil that's "good for a year" and there will be plenty of people that will believe it, I am not one of those people. changing oil is cheap insurance and is quick and easy, but slightly messy to do. the oil filter location could have been thought out a little more for sure
