BREAKING NEWS: Michigan Orders City Star/Star Petroleum Motor Oils and ATFs Off the Shelves!

The Michigan Department of Agriculture and Rural Development (MDARD) issued Stop-Use and Stop-Removal Orders for motor oil and transmission fluid manufactured, packaged, and/or distributed by City Petroleum (dba City Star) of Dearborn and Star Petroleum of Detroit after finding the products did not comply with  the Michigan Weights and Measures Act, 1964 Public Act 283.

The Stop-Use and Stop-Removal Orders prohibit the sale, offering for sale, or use of motor oils or transmission fluids manufactured, packaged, and/or distributed by City Petroleum (dba City Star) and/or Star Petroleum. These products should no longer be used, immediately be removed from store shelves or other product displays, and no longer be offered for sale. These products may cause damage to vehicle engines.


As part of an 11 month investigation, MDARD discovered that the motor oil and transmission fluids being sold by these companies do not contain the amount of product claimed. Additionally, the motor oil does not meet the viscosity labeled on the containers. For example, a container may say the product is an "SAE 5W30" motor oil, but does not meet that viscosity or other specifications for a motor oil.


"These two companies are selling sub-standard product and the Stop-Use and Stop-Removal Orders ensure Michigan consumers and business alike are getting what they pay for and protecting their vehicles," said Jamie Clover Adams, MDARD Director. "When products don't meet viscosity levels it can cause lasting damage to vehicles. So, it's vital that consumers and business stop using or selling these products immediately."


The Stop-Use and Stop-Removal orders mean no City Petroleum or Star Petroleum motor oil or transmission fluid may be sold or used in the State of Michigan.  


The City Petroleum and Star Petroleum products were primarily sold at small independent gas stations, discount and party stores. It is possible they were also sold in some oil change facilities across the state. Consumers can visit  and look under the "Hot News" section for photos of the product labels as well as information on what to look for when buying motor oil.


Note: PQIA reported on the poor quality of these products in 2011 and 2012.


BUT what about  the Other States Selling City Star?
The Petroleum Quality Institute of America applauds the state of Michigan and Jamie Clover Adams, MDARD Director, for taking action to protect its citizens by ordering the removal of City Star motor oils and transmission fluids off the shelves and out of the fast lubes. This is a step in the right direction to protect what for many is the second biggest investment they make; their cars.

But what about the other states where PQIA also found and reported on serious issues with City Star motor oils and transmission fluids, and other brands?  These states include Ohio, Illinois, and Indiana? 

What are these states doing to protect its citizens from City Star and other engine and transmission damaging lubricants sold in their states?

You can be sure PQIA has and will continue to ask these questions by knocking on the doors at the Attorney General's offices in these states and others to get answers. And when we do, you can also be sure PQIA will let consumers know the outcome.

 Note: PQIA issued Consumer Alerts and "Don't Buys" on City Star and others sold in the mid-west a number of times over the past two years. The state of Michigan was the first to take action and we remain optimistic that others will follow!
