f- The specification of 15 max is expressed in two significant figures and therefore this result meets specification.
Gulf Advanced Fuel Efficient Motor Oil 5w30
The American Petroleum Institute sets forth a number of laboratory and engine tests required to meet an API SM performance specification. Although laboratory tests alone cannot be used to establish if an engine oil meets API SM, they can be used to determine if it doesn't.
What follows is a comparison of the test results for Gulf Advanced Fuel Efficient Motor Oil 5w30 as compared to the API SM ILSAC GF-4 requirements.
The API limits for each test are shown by the yellow bars. The test result for Gulf Advanced Fuel Efficient Motor Oil 5w30 are illustrated by the horizontal line.
Viscometrics
The viscometrics of Gulf Advanced Fuel Efficient Motor Oil 5w30 meets the required targets for a 5w30 API SM (SAE J300 specification).
