I used GTX in all my bikes, (over 20 HD's) when I got this 2009 I went over to mobile 1, I run it in primary, trans and motor. my bike runs cooler. I don't know other than that what it is doing. but that's enough for me to run it.

I just made the change to Syntetic ATF and the bike likes it, good clutch shifts smooth. My other Harley i ran Ams oil and never had a problem.

It's simple physics. Synthetic oil has superior lubrication characteristics and longevity. It will reduce wear on your engine and transmission. Using anything but synthetics doesn't make sense.

I ran Red Line MTL and standard issue ATF. In both cases the clutch slipped nice and then just grabbed. Switched to HD Formula + and got the smooth clutch movement back. Strange looking stuff, almost clear and about $7.50 from the dealer so you know it's gotta be a cheap lubricant. Wondering if 10W40 Rotella would work as good.

JMO, but I believe any good quality 10W or 15W-40 or 20W-50 motor oil will do just fine in there. As long as it does not contain friction modifiers.

Mine has $2.49 a quart conventional 10W-40 in it and has for a long time.

I bought a new 2013 FLHX last May and have used nothing other than AMSOIL in all 3 holes. It works so great that I can even find N neutral and time I want. The bike runs great!

Always used Mobil 1 before and now I'll never use it again.

Which AMSOIL you guys running in the primary? Just the standard synthetic 20w-50?

Thanks

I've been using regular Rotella T in all of my wet clutch applications for the last 20 or so years or so and never had a problem. No different in the Harley.
