Powersports Oils: Why JASO?
Why Quicksilver Is JASO Certified
When it comes to engine oil needs, motorcycles are one of the most unique vehicles on the road. As the automotive industry gets squeezed more and more to improve fuel economy and emissions, automotive engine oils are becoming formulated more for efficiency, leaning on friction modifiers and super-low viscosities such as 0W-16 and 0W-20 to meet standards. Motorcycles don’t have the same fuel economy and emissions requirements as automobiles, and they are built different with smaller, higher-revving, higher HP per liter engines that typically share their oil with the transmission and clutch system.
As a major motorcycle manufacturing country, Japan’s JASO (Japanese Standards Organization) has put together engine oil standards for motorcycle use. Standards for four-stroke motorcycles include JASO MA, MA1, MA2 and MB. To earn one of these JASO levels of approval, the oil must first meet specific API, ILSAC or ACEA standards, then go beyond those standards to meet JASO standards for Dynamic Friction Characteristic Index, Static Friction Characteristic Index and Stop Time Index. These are all friction tests aimed at transmission clutch performance, a critical aspect of motorcycle performance not addressed by automotive engine oils.
While some motorcycle oil manufacturers claim they meet JASO certification, earning the JASO certification is the only guarantee that a motorcycle engine oil will perform to JASO standards as well as motorcycle manufacturer standards. In the interests of the consumer, JASO publishes a list of certified motorcycle engine oils. If it is not JASO certified, the user risks clutch wear, clutch slip, gear pitting and an oil that can shear out and result in loss of engine protection.
The JASO certification ensures the customer is purchasing an oil that meets a set, minimum quality standard for motorcycle use. Quicksilver not only certifies its motorcycle engine oils to JASO specifications, it goes beyond, formulating for maximum protection. Quicksilver motorcycle oils are high-tech, full-synthetic blends that provide superior wet clutch performance and meet OEM requirements for all brands of motorcycles. Quicksilver motorcycle oils are proven to perform in the toughest environments, including superbike racing where Bobby Fong claimed 6 wins, 11 podium finishes and finished in third place in the points championship in 2017. Whatever bike you ride, Quicksilver will protect it.
