Any engine that states Mobil 1 is the preferred/required oil, I would never use a blend in it. Even if Dexos1 meets GMs standard Mobil 1 is still better.

Walmart is selling a five quart container of Mobil 1 for $21.00. I have been running Mobil 1 in everything I drive since 1979, and have never had an oil related problem in any of the vehicles I have owned since.

#PI0215: Oil Filler Cap Identification and Changes - (Aug 23, 2010)
Subject: Oil Filler Cap Identification and Changes
Models: 2011 Cadillac CTS-V, DTS, Escalade, Escalade ESV, Escalade EXT, STS
2011 Chevrolet Camaro, Corvette
Equipped with Engine VINs E, F, J, P, S, T, W, 4, 6 (RPOs L37, LSA, LAU, LD8, L37, L99, LS3, LS7, LS9)
--------------------------------------------------------------------------------
The following information may be helpful in identifying and avoiding unnecessary parts replacement at the time of Pre-Delivery Inspection (PDI).
Condition/Concern
Technicians may notice during PDI that the oil filler cap on the 2011 vehicles no longer has the "Mobil 1®" logo printed on the cap.
Previous Design Oil Filler Cap
Revised 2011 Oil Filler Cap
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.

I know that Mobil 1 is good oil, but I've been using Royal Purple 5W30 with Napa Gold filters. Anyone have any thoughts on that combination. Thanks Bill with his orange crate

Amsoil for me all the way. In everything I own. Of coarse I'm also a dealer.

there are some good rebates on oil right now. valvoline has a good one at engineguarantee.com through o'reilly. bought 10qts of synpower today at o'reillyfor $3.99 each. i will send in my $25 rebate when i do my next oil change (since you have to send 5 of the rings in).
with taxes, it was 42.29. so, i paid $1.73 a qt with taxes. $8.65 per oil change.
about a week ago i bought a bottle of QS ultimate durability full syn for $19 at wallmart. with a $10 rebate... around $10 including tax.
since i started rebate hunting, i have found that i can often buy syn under $2 a qt.
