I agree with Red. I have been using Amsoil 20-50 in all three holes every 5,000 miles, 18,700 miles now with no problems. 19' FLHXS.

I ran the Mobil V-Twin 20-50 and the valves rattled like hell. The engine sounded awful. Switched back to the SYN-3 and it runs quieter. I am running Red Line Synthetic Primary along with Red Line Synthetic Transmission with Shock Proof oils. It all is a personal preference deal. I do run the K-N Filters.

Question for primary. Manual shows drain plug location, and removal of clutch insp cover, but for refilling does not say how to check level. I assume, with bike level, I fill it to bottom clutch inspection opening?

You do not. That will be overfull
Observe the level on the hub ( derby cover off) prior to draining.
Add the # of ounces spec`d for your bike
Observe that the level is now close to first view

Ok glad I asked. I saw it's 38oz for "wet" refill. That surprised me, since trans only take 28oz. I figured would be the other way around. Ok so no real level mark. Thanks
