Change you oil back to OEM it will stop
making a flat statement like that, is fraught with emotions, and zero fact.
there is nothing special about Honda's oils, they are obtained from the Lowest Bidder, and that supplier changes from time to time.
I used to use Delo 400SE 15w40 when I owned gl1500s.
when that went away, and I bought an 1800, I changed to Rotella because Walmart sells it for ~$13/gallon
I have used T5 10w30, but changed to T6 5w40 for a personal reason.
IMO, the ADG problem is caused at engine startup by folks who wrap up the engine as soon as it starts..... using a 5w oil will drastically reduce the load on the ADG as it tries to spin up the Alternator when the engine starts.
( I have seen some folks state it is because people wrap up the engine to ~6,000 rpm )
I make it a point, to never touch the throttle when starting the bike, until after it idles back down and the alternator is working.
Replacing an ADG gearset is not cheap.
for those unaware of the Rotella oils, the T4, T5, T6 are pure synthetics.
at least the ones I have been buying are.
