One reason is that changing the oil too often can actually increase wear. Why? New oil has detergent additives which break down over time, so the oil is formulated with higher than optimal levels when the oil is new, so that they will last for the duration of the expected oil change interval. At the high levels when new, these additives interfere with the effectiveness of some of the anti-wear additives, resulting in increased wear.

I realize that this will sound absurd to some people, but it's what has been learned from actual testing, and published in technical papers from the Society of Automotive Engineers.

Cars and trucks have big radiators which regulate temps. My ride, at least, doesn't, and generally operates at temps around 10% higher than the 212 degrees automotive oils were designed for. Frequent (3000 mi) changes give me piece of mind and an earlier chance to inspect drain plug magnets and the innards of my (permanent) filter. Overkill ? Probably ! I'm good with it, its only oil.
