The HD dealer said you have to change the primary & transmission oil everytime you change the motor oil? Is this correct?

And does everyone do that?

Thanks!

 

NO! Read the service manual and follow. Some folks are way to ****. Don't know about your FB, but my Ultra is 5K, 10K, and 15K. I followed it for 125K miles with no issues.

 

The HD maintenance schedule calls for trans at 1k then 20k, . Primary is 1k, 10k, 20k, 30k

 

Perfect! Thanks for the info!

 

I go ahead and change all mine every time, hell its only 2 more quarts, and I can tell a difference in how mine shifts after change. Im running syn 3 in all. BTW I have 2013 deluxe.

 

+1...this is the preferred method. Like he said, it's only two quarts and another 15 minutes. Why wouldn't you?

 

Is this what you guys use? Or is there a cheaper oil to use?

According to a poll here in the forums, most people use Mobil 1 V-Twin which is cheaper, or Amsoil, I use Royal Purple, IMO use any good quality syn. and you'll be fine.

 

Perfect! Thanks!

 

Oh Gawd nooooooo....another oil thread!
