No, the title isn't some cool metaphor - this post really is about changing the oil. Anyway, the quick change places would have you change your oil every 3,000 miles. HOWEVER, they want to sell you oil, so they might be erring on the side of caution, so to speak. My car's manufacturer recommends changing the oil every 10,000 miles. HOWEVER, they want to sell me a new car. So, after many years of wondering about this conundrum, I've decided that the sweet spot between unnecessary oil changes and waiting too long must lie between those two extremes. Hey, it sounds good, right?
