If you are set on 10w-30, Honda GN4 oil is like $8/qt on amazon when you buy it by the gallon, and is what they designed the bike to use. You would have to buy two jugs the first time since it holds 5 qts, but still not bad.Neither of those weights work with the Gold Wing which calls for for 10W-30, but that's my fault because I didn't specify weight in the thread title...
I personally would just use Mobil 1 HM 10w-40 and not worry about it. It also conveniently comes in 5 qt containers.
