Tremendous trans-primary fluid

When it comes to Harley Davidson Sportster and Buell primary trans assemblies this oil is as close to perfection as you'll find. Offers up smooth shifting and outstanding clutch feel.

Great Oil

I've been using Castrol Synthetic 20W50 on my air cooled Indians for about the last 6 years and it's been great. I was changing every 3K but have since changed to 5K oil changes due to this oil maintaining its structure and properties easily to the 5K mark. As always Walmart has been a good source for this oil.
