Bullseye Motor Oil 5W30 Motor Oil API SC/CC
Bullseye Automotive Products, Inc., Dolton, IL
Test Results on this sample indicate the product can cause damage to a passenger car engine.
Purchased in: Wickliffe Shell, Austintown, OH
Date of purchase: July 13, 2011
CONSUMER ALERT: The label on this product states it is an "SAE 5W30" motor oil. In fact, PQIA's test results show this product is not a SAE 5W-30, does not meet the requirements of an API SC/CC, and does not meet any other recognized specifications for a motor oil. In addition, the viscosity for this oil is 75% below where it should be for a SAE 5W-30.
Further, this product is labeled as meeting API SC which is an obsolete specification. The API cautions this specification is "Not suitable for use in gasoline-powered automotive engines built after 1967. Use in more modern engines may cause unsatisfactory performance or equipment harm."
NOTE: PQIA sampled this brand in January of 2011 and issued a CONSUMER ALERT. This is a new sample purchased in July 2011 at the same location. Test results show this product is very similar to the previous sample tested, and, whereas it can cause damage to a passenger car engine, it remains in the market.
