American XT Premium 10W-30, API SM | ||||||||
The American
Petroleum
Institute sets
forth a number
of laboratory
and engine tests
required to meet
an API SN ILSAC
GF-5
performance
specification.
Although
laboratory tests
alone cannot be
used to
establish if an
engine oil meets
API SN, they can
be used to
determine if it
doesn't.
The following is a comparison of the test results for the sample of American XT Premium 10W-30 tested with the API SN ILSAC GF-5 requirements. |
||||||||
Viscometrics | ||||||||
The viscometrics meet the required targets for a 10W-30.
