Harley Trans & Primary?

[RISUPERCREWMAN]

What do you guys use for a Syn lubricant in the 6-speed trans & primary holes?

I use Amsoil 20w-50 in both on my FLSTC. Excellent stuff, use with full confidence.

 

[kballowe]

Mobil 1 75W-90 in the transmission

Rotella or Delvac 15W-40 in the primary chaincase - whichever one I can catch on sale.

Amsoil 20w-50 in engine and primary with 75w-110 in tranny. However, gettin tired of paying shipping and handling and probably goin to Schaffers Supreme 7000 20w-50($6.50qt)or 9000 5w-50 ($29.98 gal) which I can get locally...

Correction: Amsoil 75-110 or 75-140 in the Tranny.
