I agree and will do the same at my next (6000 mile) change. I've already checked, and my favorite oil change pan fits fine under the bike when it's on the the side stand. I probably won't wait till 6000 though - probably change around 4000.
I bought an extra quart of 10w50 from my dealer for $13.69 and haven't checked other sources yet. I was going to check and see if Wallyworld carries it. I do want to pick up some new washers though - I've had leakers before reusing them.
Walmart carries the Mobil1 4T 10w40 for about $9-10 which is the same price as the Castrol Power 4T at Advance Auto...so obviously they watch each others price point. I'll change at 3-4,000 or once every fall before layup.
