New Harley-Davidson Brand Synthetic Gear Oil
While checking out the "New Arrivals" on Harley's website, I noticed they now have a "Heavy Synthetic 80w-140 Gear Oil" approved for '84 and later transmissions and primary chaincase applications. I was under the impression that you should never use a gear oil in the primary. Am I correct? Is HD recommending a product that is unsafe for the primary?
