There's enough info and debate to make you go blind, if you try and read it all.

As for me, I ran conv. dino in my '05 FXD, only because I had the prepaid PCMP and was getting an oil change every 2500 miles. It was cheap and I did not know better.

I picked up my '07 RG in November with 7900 miles on it and immediately took it to Mexico. It would have had 100% dino in it until then, as it was a dealership bike pulled out of their rental fleet. When I got back a few days later, I did an oil and filter change, and went to 100% syn in all holes. Holy **** what a difference....shifted better, ran cooler, shifted quieter, found neutral easier.

I am still on that oil change for about another 1000 miles, but I will be sticking with syns.

I used Mobil1 V-Twin 20-50 in the case, Mobil1 HD Gear Oil 75-90 in the trans, and Mobil1 Racing 4T 10-40 in the primary.

There are a lot of other excellent syns, or syn blends, out there too....Amsoil, Royal Purple, Redline, Syntech, Syn 3, etc etc.

With all the debate about how many miles to clock before switching from mineral to synthetic, can anyone explain why H-D ship the CVO SE bikes with Syn from the factory ?
