Distributed by American Sales Company, Lancaster, NY
Purchased in: Giant Food Store, New Cumberland, PA
Date of purchase: March 17, 2012
All tests conducted on this sample meet the specifications for API SL 10W-40 Engine oil.
Note: Whereas the label on this product states "Giant SAE 10W-40 is a premium-quality, high detergent automotive oil specially formulated to meet the stringent lubrication requirements of today's engine," the label does not adequately advise consumers that the API SL Service Classification this product meets is formulated for vehicles manufactured prior to 2004.
The Standard below are for the latest specification (API SN GF-5), and the Ranges and Averages are based on the 13 major brands of API SN ILSAC GF-5 tested in September 2011. Click here for more on API Service Categories.
