Crazyjoe, chill out man, it's all about personal preference. If someone is used to changing their oil at 3K miles, that's their choice. I personally change oil and filter at 3K. I believe like the other guys that the key is changing the oil at the right interval, be it 3K or 5K. As for monster cables, THEY DO make a difference, better cable, better insulation, better connectors, the average joe may not notice a big difference if any, but people looking for the highest quality sound will notice.
