Dexos is a GM oil requirement. It can be either full synthetic or semi-synthetic. See the article below it pretty much explains what the deal is: Looks like a money grab and a lot of baloney to me. Mobil 1 met the Dexos standard before the Dexos name came about..

I normally do not jump into these types of conversations, but here goes. Take this for what its worth or not. I could just be getting too old to know better.

I have been working in a dealership for over 25 years. My current dealership is multi-line. We have GM, Nissan, and Chrysler.

First, I can tell you without question, Nissan and Chrysler both require verifiable documentation on oil changes for warranty. Hand written shop orders and some scattered receipts DO NOT count. I cannot comment on GM, but I can find out if needed. I have had two bad Chrysler engines and one bad Nissan engine in the last twelve months that were turned down due to lack of provable maintenance.

Second, I am a life long Chrysler tech and a newbie Nissan tech. We have never really had oil issues. But I watch the our GM techs pull engines out on a weekly basis to put in new pistons and rings. GM most certainly has oil issues, and it's always the ring pack stuck in the groove. Walk into any GM dealership and the odds are they are going to have an engine out putting pistons and rings in it. GM switched it's oil requirements right as their oil issues started to get severe. They realized a little to late that with the super light ring tension they are running, they needed better and lighter oil.

Third, I never seem to understand why using a manufacture specified oil seems so foreign to some. If it's good enough for the manufacturer, and required by the manufacturer during warranty repairs, how bad can it be? Some say price is an issue which I find hard to believe, after all if you can afford $60k for a truck the oil shouldn't be an issue should it?

I would use the oils that Support our sport. Catrol Lucas Amaile all support us why not support them?

Thanks for the input. As I stated I have always used Dino oils but they just don't measure up for the new standards. It appears there is no new technology in dino oils. I have always used Kendal or Brad Penn and have been very happy with these products. I used the Penn racing oil in my Buicks and will be using this oil in my daily drivers. Thanks again

Nobody's mentioned Shell Rotella 15-40W for GM Diesels. Have used them in all my diesel trucks and never had an issue. Are the newer trucks requiring something different?

Will be looking at Shell Rotella synthetic for the winter. Any other recommendations? This is a 2007 GM Duramax. LBZ motor.

Thanks,

Mike

Not sure on the diesel side but all manufacturers are going to lighter oils for pump ability and deposit issues.

I use Mobil 1 in everything that I run. From the 70's push mower(FIL gave it to me in 1981), the Dixie Chopper rider, my 139K miles 2003 Harley Electra Glide, 2002 GMC Sonoma 150K, 2013 Buick Lacrosse, and of course the 73 Buick Apollo J/SA that had managed to win a few races with my brother at the wheel. My old 1992 Chevy half ton P/U that towed it back and forth across the country with it's 305 that had over 200K+ miles on it with nothing more than two alternator changes.

Check out the videos taken here at Mobil's (ExxonMobil now) research facility.

Then there was that BMW that we ran for over 1 million miles a few years back with 7,500 mile oil changes.
And of course I would recommend Delvac 1 for you diesel fans!
