The was a time when the Moco warned against synthetics, mostly because they didn't have an HD product to compete with synthetics. That's the way the world turns in the corporate world. And HD is not run by enthusiasts anymore...

The only engineering contribution towards fluids would be an opinion on whether or not whatever fluidt the Moco wants to use/recommend will damage anything before warranty runs out.....
Precisely!

Nahhh, Not going to get in what the best brands are. There are many reasons an engineer will spec specific type lubricants for an application. If at one time HD did not recommend synthetic oils it may have had to do with a possible incompatibility with some of the components (seals, friction plates) in the Powertrain. Maybe they at that point had not fully tested their products long term with those different oils?


A large company who can be liable for premature failure of its products and open to huge class action suits and government recalls...something tells me they are not letting the guys and gals in accounting making the calls on engineering.
