by HarleyJerry Good stuff
I use this on my 2014 Heritage Softail and 2016 Sportster 1200. It works and does what it is supposed to do and costs less the Harley synthetic or Mobile 1 and performs just as well.

Rated 5 out of 5 by DucMan Good oil but way overpriced
I have used Castrol GTX 20W-50 regular motor oil in the past in my old school bikes but wanted to try their new RS V-Twin Full Synthetic in my '91 Ducati 900SS Project Bike. It works just fine but it is in my opinion way over priced and not available in the 5-Quart Jug like their other oils. The Ducati has a dry clutch so I will be moving to a more affordable full synthetic brand.

I use this stuff because it's a buck cheaper than Mobil 1 V-Twin and pretty much, the same formula.

Rated 5 out of 5 by Boreese Best oil for your HD
Just love this oil. Use it in my 2002 HD Dyna and my wife's 2005 HD Sportie 1200. Keeps both bikes running smooth and cooler and living in the desert, you really want your bikes running cooler. Tried the other synthetic brands and none of them run the bikes as smooth as this Castrol synthetic. Even cranks the engine easier when they start up. Put it in your Harley.
