I totally understand that some folks don't want the hassle. But, on the scale of things that have a great payback ratio by doing your own labor, this is serious bang for the buck. 1 bottle of Royal Purple costs $20. That covers at least 3-4 swaps. The pump and extra hose cost $20. I figure that every time I do it, I am saving over $200. I tend to plan it when I already have the car in the air for some reason. Brakes, belt and tensioner, etc. Thus, making it a gravy job, providing that you like your gravy smelling like something that comes out of a very sick cat.
