SuperS dexos™ approved SAE 5W-30 Motor Oil

Smitty's Inc. Roseland, LA

 

Purchased in: D&D Auto Parts & Supplies, South Plainfield, NJ

Date of purchase: 3-19-2012

 

 

 

 

The results of the tests conducted on this sample meet the requirements of an API SN and ILSAC GF-5, SAE 5W-30 Engine oil.

 

Whereas the manufacturer of this oil states that it meets API Service Categories SN and ILSAC GF-5, the product is not labeled as licensed by the API. The label does, however, show the product is licensed under dexos1 which encompasses API SN and ILSAC GF-5

SuperS dexos™ Approved SAE 5W-30 Motor Oil
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 SuperS dexos™ Approved SAE 5W-30 Motor Oil tested with the API SN ILSAC GF-5 requirements.

 
Viscometrics

The viscometrics meet the required targets for a 5W-30.
