Superior, WI (Vocus) July 28, 2009
AMSOIL INC. of Superior, WI has released an updated motorcycle oil white paper report. “A Study of Motorcycle Oils, Second Edition” is a 28 page document comparing the test results of 32 leading 10W-40 and 20W-50 motorcycle oils. Each oil was subjected to 12 tests conducted in accordance with American Society for Testing and Materials (ASTM) procedures. The document also includes a concise informative introduction detailing the differences between motorcycle and automotive engine applications.
Comparison points addressed physical properties, performance and pricing. At the conclusion of all testing, each oil was assigned a score for each test result. Because a quality motorcycle oil must perform well in many different areas, results in all categories were added together to produce an overall total for each oil.
A free copy of the report is available by calling 1-800-777-8491.
