In the past, Harley-Davidson® did not recommend the use of synthetic oils in H-D/Buell® motorcycles. Why is H-D introducing a synthetic now?
Because Harley-Davidson cannot test and certify all available synthetics on the market nor control their oil and additive formulations, we have discouraged their use. However, Harley-Davidson, in close partnership with our suppliers, analyzed available petrochemical technology and developed a custom-blended candidate fluid that can be used in all three cavities of a Harley-Davidson/Buell motorcycle. This product has been exclusively designed for Harley-Davidson and is the only synthetic product TESTED and CERTIFIED by Harley-Davidson engineering for use in H-D/Buell motorcycles.
