Default SG fluids preferred

What is everyone running in fluids (Oil, Trans. and Primary). I have a 14 SGS and want to hear your preferences. Thanks ahead of time.

My 2014 RK: Syn3 in the engine and Formula+ in the primary and transmission. You can use the search function for "oil" and you will be reading all night.

Harley has a New Formulation called SGS ne plus ultra. Harley WILL void your warranty if you do not use at the latest, the 1000 mile checkup

agree....please read the oil thread and do a search on this thread. there are more than enough comments to keep you reading for a month.
Personally, I signed up for preferred customer through Amsoil and buy a case of 20w50 oil and use that. Everyone has their own preference....just use quality products and follow recommended changes.
