LukOil Synthetic Blend  
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 LUKOIL Synthetic Blend  as compared to the API SM ILSAC GF-4 requirements.

The API limits for each test are shown by the green bars. The test result for LUKOIL Synthetic Blend  are illustrated by the horizontal line.


The viscometrics of LUKOIL Synthetic Blend  meets the required targets for a 5W-30 API SM (SAE J300 specification).



Volatility Phosphorus
The volatility of LukOil Synthetic Blend  meets the parameters required for an API SM ILSAC GF-4 designation.
