Exemplary Labeling
The Petroleum Quality Institute of America points out the back label on this product as an example of how a marketer can and should provide consumers with proper guidance about applications where the product can be used and where it should not be used. The PQIA encourages such labeling, especially when ATF products include such language as “Multi-Purpose,” “Universal,” “Multi-Vehicle” and others that can be interpreted by a consumer to mean it’s appropriate for use in virtually any automatic transmission.
