Now granted, i KNOW there's a plethora of other choices out there for your primary case, but I couldn't help but notice on the Syn3 (standard Harley synthetic engine oil) bottles it reads:
"For Use In Harley-Davidson Engines, Transmissions, and Primary Cases"
On the Formula+ bottle it reads:
"Transmission & Primary Chaincase Lubricant"
So now, I gotta ask... WHAT THE FRIGGIN HELL? Which one is the way to go? And what's the difference when it comes to the Primary Case? Clearly these Harley products are saying either will work... so, i submit to my forum friends, which is the way to go? Opinions? Facts?
For the record, the SERVICE MANUAL (yes i have one) says to use ONLY FORMULA+ Tranny Lubricant!
