Purchased in: Cherry Hill Citgo, Cherry Hill, NJ
Date of purchase: 6/2/2012
Consumer Alert: The labels for this product claim the oil is a 5W-30 motor oil meeting the warranty requirements for API SJ, SH, SG, and SF. The labels also bear the API certification marks for API Service Categories SH/CD and an unidentified ILSAC specification. PQIA's test results for this sample show the oil is a not a 5W-30, but rather a 10W-20. In addition, although the labels on this product display the API certification marks, a check with the API shows this product has not been certified by them since 2005.
The analysis also shows lower levels of additives than would normally be expected for an SJ. SH, SG, SF, CC, CD engine oil. API SH/CC is an obsolete specification that is not recommended for engines built after 1996. The label on this product fails to give adequate warning to consumers about its limited use.Use of this oil could potentially cause damage in modern automobile engines.
