Alert! CONSUMER ALERT

 

City Star Automatic Transmission Fluid 

City Petroleum, Dearborn, MN

 

Purchased in: Toledo Food Market, Toledo, OH

Date of purchase: August 26, 2012

 

 

CONSUMER ALERT:  The results of the tests conducted on this sample show a product that does not meet any definition of Automatic Transmission Fluid.  The very low viscosity, lack of additives, and high silicon level indicate this product may cause damage to automatic transmissions.

 

 

Note: In addition to now finding serious issues with City Star ATF, PQIA issued a Consumer Alert on City Star engine oil in July 2011, and on October 13, 2011, North Carolina officials ordered that three grades of City Star Motor Oil be removed from retail stores throughout the state because of the manufacturer's failure to meet stated viscosity claims.

d- ASTM D5185-09 Reproducibility by element.

 

 

 
City Star ATF
General Motors and Ford Motor Company has set forth a number of laboratory and rig tests required to meet the former Dexron III and Mercon performance specifications. Although laboratory tests alone cannot be used to establish if an ATF meets these specifications, they can be used to determine if it doesn't.

The following is a comparison of the test results for the sample of City Star ATF tested with the Dexron III/Mercon requirements.

 

 
Viscometrics and Flash Point

The viscometrics and flash point of the sample tested do not meet the required targets for a for a Dexron III/Mercon ATF.
