This archive contains a historical record of
AMSOIL performance tests and technical studies that are now obsolete
and may not be representative of oils currently on the marketplace.
The test results posted in this section reflect properties of oils
available for purchase at the time of testing. The test results do
not reflect properties of those oils reformulated subsequent to
testing. Therefore, these publications are not available for
