Petroleum Quality Institute of America

The Petroleum Quality Institute of America (PQIA) is an independent resource for information and insights on the quality and performance of lubricants in the marketplace.  Our mission is to serve the consumer of lubricants by reporting on the quality and integrity of lubricants in themarketplace.






Bullseye Automotive Products 5W-30, API SC/CC

Manufactured by Bullseye Automotive Products, Dolton, IL


Purchased in: AANNUS Corp., Phillipsburg, NJ

Date of purchase: 3-19-2012






Test Results on this sample indicate the product can cause damage to a passenger car engine.


This product is labeled as a 5W-30 motor oil, however, the PQIA test results on this sample show the 100șC viscosity is 34% below the minimum specification for a 5W-30. In addition, the CCS viscosity is 41% higher than the maximum limit for a 5W-30. 

The product claims to comply with the obsolete API service category SC/CC, but the test results show the additive levels to be well below that required for SC/CC.  In addition, the levels of silicon, aluminum, iron, sodium, and potassium are indicative of used oil.  This oil should not be used in automobile engines as it could cause serious damage to most engines on the road today.


NOTE: This is the third CONSUMER ALERT issued on the Bullseye brand. The first was in January 2011. A second consumer alert on Bullseye was issued for a sample tested in July 2011.

b- Standards, shown in yellow are established by API, SAE and others. Ranges, shown in teal, represent the high and low data for the 13 major brands of API SN ILSAC GF-5 tested in September 2011.

c-Test Method for metal analysis is ASTM ASTM D5185.

d- Although silicon is used as an antifoam additive in lubricants, concentrations above 7ppm have been linked to contamination from abrasive material,

e- Average of the 13 major brands of API SN ILSAC GF-5 tested in September 2011.


Bullseye 5W-30
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 viscometrics for the sample tested do not meet the requirements for a 5W-30.
