A Oil Question

I've got a 2008 flhx and currently run the HD synthetic oil in all three holes. I've decided to switch over and buy Amsoil online but I have a question I hope someone can answer, I'm going to buy Amsoil 20w50 synthetic for the engine and primary but which should I order for the tranny severe gear 75w90 ----75w110 ---- 75w140. Thanks

I heard that Harley wont warranty the motor, trans, & primary if you don't run hd oil.

Bullshit!!! Harley can't make you use their products in your bike. Just make sure that whatever you use meets Harley's requirements and there won't be any problems.

75/140 seems to be a very popular viscosity for the tranny. Might want to consider 10-40 for the primary

BMW does. If you blow your motor the first thing they do is test the oil. Don't ask how I know...

Hey Mike it maybe funny to you! and you want HD BMW showdown!!!!!

But Beemer's don't fail very often, I've never seen beemer on the side of the road needing help!

So start you own thread on BMW's vs HD's to death.

When you buy a new HD, Document the h3ll out it if you do your own work!
