Dear Mr. Scanlon:
Thank you for your recent letter requesting information on
Harley-Davidson's one-year, unlimited mileage warranty when Synthetic
Lubricants are used.
Until now, the Motor Company has never supported the use of synthetic
products in our vehicles because there had never been any test
validations completed on the numerous formulations in HD/Buell
motorcycles to determine the viability of using these products on
Harley-Davidson products until now.
We have developed a specially formulated synthetic fluid called SYN3.
This fluid can be used in Harley-Davidson engines, transmissions and
primary chaincases. This product had been exclusively designed for
Harley-Davidson and is the only synthetic product tested and certified
by Harley-Davidson engineering for use on HD/Buell motorcycles.
The use of a different brand of fluid does not void the one-year,
unlimited mileage warranty unless it can be confirmed that the use of
such products was the cause of the failure.
Thank you, Mr. Scanlon, for taking the time to write to
Harley-Davidson and allowing me to answer your questions.
Sincerely,
Lisa Sagen, Powertrain Customer Service
