Is it just me, or are oil changes these days massively overblown? When was the last time you heard of someone's engine seizing? The vast majority of problems people experience with their cars in the first 100,000-150,000 miles have absolutely nothing to do with engine lubrication. It's shit like fuel pumps, transmissions, suspension/front end, exhaust, electronics, starters, alternators and so on. I'm not saying that you don't need to bother changing your oil, but I think it's fairly amusing when people trumpet changing your oil every 5,000 miles as the be-all, end-all of car maintenance and longevity.
Sure if you plan on driving your car past 150,000 miles then it becomes more of a concern, but very, very few people do that.
