when you factor in the shipping (unless free) it's not that great a deal. I use locally available (autozone) Mobil One Synthtic V Twin oil @7.99$ a quart. All my bikes have used this for many years. Also, Mobil synthtic hypoid gear oil for the rear transaxle too...good stuff.

Have been buying this from the dealership. Not any more! Never seen 0W30, is that supposed to be 10W30? Will be ordering it here from now on.

This is the oil I'm going to stick with. It's a quality product that keeps my engine and transmission shifting very smoothly. Also considering 5,000 mile change intervals it's that good.

Shifting is much smoother with this over regular oil. Very satisfied with performance. I may go full synthetic next time to see if can get even better. Will definately stick with the Honda brand either way.

Great price from WingStuff compared to stealership .... don't know I see much difference from the GN4 with shifting as others have commented, but each wing is unique. I always change oil around 4-5K, so when draining the old, still looks new.
My local stealership mechanic actually tried to down-sell me (a new one for me) the last time I bought there, telling me that all of his mechanics, several with wings, just run regular oil, but still a hot topic of debate.... perhaps I buy too much into the synthetic or partially-synthetic claimed attributes, but hey, guess its up to your personal views.
