Did my first oil change today. All went well. The hardest part for me was getting my V&H muffler off. I wiggled and wiggled it for about 30 minutes before it decided to work with me. I could turn it the whole time but could not get it to slide. Taking off the header was not bad at all. I had to unhook the floor boards and clutch fluid reservior to make it easier. Before I thought about getting an ORK for it but $200-$300 versus about $20 made my decision pretty simple. I figured if I can tear apart airplanes, tear apart heavy machinery, an oil change on my 09 Silverado should be pretty easy. I figure the more I do this the easier it will be. If anyone else wants to tackle this on thier own, I suggest you use YouTube and see how others have done it. Doing so sure helped me out.
