No problem. One other thing I forgot to mention, is make sure that the rubber gasket for the old filter comes off when you remove it. Although it has never happened to me, there are some who have had the old gasket stick to the mounting interface on the engine. If you put the new filter on over the old gasket, you will more than likely have an oil leak.
I've gotten to where it only takes me about fifteen minutes to do an oil change at a cost of around $20.00. If you have to buy the tools for the first one, they will pay for themselves on the first change. Around here the cheapest rate that I know of is about $50.00, so it certainly makes good financial sense to do it yourself if capable.
