I'm just saying that a synthetic oil isn't going to make a difference unless you're planning on keeping it for 200,000 miles or more.

Oil seems to be a big peer pressure thing. Same goes for 3,000 mile oil changes. They are a waste of money for the vast majority of people. It depends on your driving conditions, distance, weather, etc. If all you do is highway long trips, you're fine with 7,500 mile changes. Short trips on the other hand.......

But whatever makes people feel good.
