The following information may be helpful in identifying and avoiding unnecessary parts replacement at the time of Pre-Delivery Inspection (PDI).

Recommendations/Instructions
Important: DO NOT replace oil filler caps because they no longer display the Mobil 1® logo.
Starting with 2011 vehicle production, GM no longer specifies Mobil 1® as the required oil for the above vehicles. A new oil specification called Dexos I has been created, which a variety of synthetic and synthetic blend motor oils meet.
Note: For additional information on available Dexos 1 oils, please refer to PI0175.
• 2011 vehicles equipped with DOHC V6 engines (RPO LF1 and LLT) are no longer built with Mobil I logo caps. These vehicles should be serviced in accordance with the Dexos I standard.
• SRX models with the DOHC V6 (RPO LAU) engine used the "Mobil 1®" cap from the 2011 start of production to August 1, 2010.
• All Chevrolet Corvette and Camaro models along with the Cadillac DTS, CTS-V and Escalade models will continue to be built with the "Mobil 1®" style cap until November 2010.
