Synthetic Oil Change ....Now the Transmission is Silky Smooth (also posted on VFRD)

I just completed an oil change at 4500 miles, using Amsoil 10W-30. There is a noticeable difference in the transmission now. It's like night and day. Before the oil change, in "D" mode, the transmission was jerky and bucked a lot in the lower gears. Now, the shifts are seamless and silky smooth, just like warm "butta". It's even a joy to drive in "D" now. Also, the engine seems quieter and the fan does not cycle on nearly as often. I've always used Amsoil in all my previous bikes and achieved similar results, but they all had manual transmissions.

Please don't misunderstand me. I am not promoting Amsoil or any other brand. I'm sure any other brand is just as good; and I'm definitely not trying to start another oil thread. (I just happened to get a good deal on 5 quarts). All I'm saying is that the synthetic oil transformed my DCT into a beast. Just wanted to share my experience. I hope I didn't offend anyone or any policy.

Thank you,

I am a Caterpillar mechanic by trade and the smallest amount of grit/dirt does not sit well with most solenoids. I would think early and often with the oil changes is in order for the life of the bike to prevent premature failure of the system.

 

I don't want to start an oil war either, but I have to agree with you. I had the same experience with my Buell Lightning. I had Mobile One V-Twin synthetic oil in the tranny and engine. The tranny was clunky and sometimes it was hard to get it out of one gear and into the next. I switched to Amsoil and it all went away. Very smooth shifting now. The engine seemed to run about the same as best as I could tell, but the transmition was very much improved with the Amsoil.
