  FOLLOW-UP TESTING ON GOLDEN STALLION

On July 11, 2012, PQIA issued a Consumer Alert on Golden Stallion Super Pro Plus 10W-30. Days after publishing the alert, PQIA received phone calls and a letter from, Dean Mohammad, president and CEO of US Global Petroleum, the manufacturer of Golden Stallion. The letter does not dispute PQIA's analysis, but claims a limited quantity of bottles were incorrectly labeled and production was immediately stopped. Further U.S. Global Petroleum encouraged PQIA to proactively test its products and visit its facility to see its "state-of-the-art packaging equipment" in action. 

In an effort to assure the quality and integrity of lubricants in the marketplace, PQIA took US Global Petroleum up on its offer to visit its facility and proactively test its packaged and bulk products. We did so on two occasions, including September and October 2012. During that time, we randomly pulled samples of quart bottles from inventory and two samples from discharge lines leading to bulk tanks.  As shown below, each of the samples tested meet their stated specifications as an API SN, ILSAC GF-5 for the 5W-, and 10W-30 viscosity grades.

Note: Test results are specific to the sample(s) tested. The results are not intended to reflect the quality of other brands and visosity grades manufactured by USGP, nor are they an endorsement of any products.

a- Standards, shown in black 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.

 b-Test Method used for metal analysis is ASTM ASTM D5185.

 c- ASTM D5185-09 Reproducibility by Element.

d- Silicon is slighly higher than expected in a new oil sample.
