Screamin’ Eagle® SYN3® lubricant has updated technology that allows the oil to stay fresher longer. It maintains fluid film thickness and low-temperature pumpability for improved wear protection over the oil’s life. It’s manufactured from a custom-designed blend of additives and base stocks by Harley-Davidson® engineers to provide optimal performance and protection for your motorcycle.
As the only high-performance oil that can be used in all three cavities of a Harley-Davidson® motorcycle, SYN3® lubricant offers improved wear protection, high temperature detergency and superior overall field performance.
HOW IT WORKS
Both synthetic and mineral based products are derived from the same crude oils. However, unlike mineral-based counterparts that may inherit contaminants from the refining process, synthetic lubricants are made from custom refined base stocks to have the desired properties for specific purposes. The engineers have complete control of the process from the molecular level to the finished product.
WHY IT'S BETTER
Exclusively designed for Harley-Davidson®, SYN3® has the optimum blend of additives, providing your motorcycle with the best level of protection. Backed by hundreds of thousands of miles of testing, SYN3® benefits include:
Our engineers have tested powertrains under controlled environments to make sure every additive is the correct additive and the right amount. The end result is the best oil you can buy for your Harley-Davidson® powertrain.
Formulated to improve wear protection, reduce oil consumption and reduce engine deposits.
Oil will not break down under hot temperatures and will remain stable and not “gel” when the temperature is cold.
Premium detergents keep engines, transmissions and primary chain cases cleaner.
Meets the anti-wear lubricity requirements of all transmission gears.
Gives proper lubrication to all primary chain case components.
Delivers smooth, sure clutch operation.
Improves seal and gasket performance.
Offers superior performance in high-output engines.
