Even dinosaur oil is of far higher quality than the oil of 25 years ago. Oils have various detergents and other additives that give far longer protection against acids and other harmful pollutants produced by internal combustion. Therefore, it is my opinion that too frequent oil changes do not accomplish anything to extend engine life. Having said that, I change the oil in all of my internal combustion engines more frequently than recommended by the manufacturer. The days of the 3,000 mile oil change are long gone, although my observation is that many people who say they change oil that often, don't. My 12 year old VW Jetta diesel gets oil changes at 5 to 6,000 miles, religiously, instead of the 10k recommended by VW. At 224,000, it is going strong. My Vulcan gets a lot less miles on it and once a year is quite fine, especially since I use the Kawasaki full synthetic in it.
