honda hp4 oil

Hello,

I have a 2005 Silverwing with 1500 miles. I changed the oil 2 years ago when the bike had 500 miles and used Honda HP4 oil (without moly). I used this oil in the final drive as well. I know the bike has low miles but i figured i would change the oil again. Since i already have a quart of HP4 (without moly) left, i was attempting to purchase more. Yikes....now i noticed you can get HP4 with Moly!!! Which one do i need? does it matter? can i mix them?? Thank you so much.
