Can I use any 5w30, or does it have to be dexos approved? No warranty. 6 month 5,000 interval. I'd just use a conventional oil.
2011 Silverado do l have to use dexos?

Instead of using conventional 5w30 every 6months/5k miles I would much rather go with good 5w30/0w30/0w40 synthetic with 1yr/10000 miles. Cheaper that way, saves more time, and provides better protection.
Conventional will do the job, but over time it cokes up the piston rings, while synthetic is just more resistant to the temperatures around the combustion chambers, even with a longer OCI.

Synthetic is always better... there is no downside to a synthetic - so why not choose a Dexos compliant oil? Unless you beat the heck out of your truck all the time or do tons of short trips 6 months/5k miles is pointlessly soon.
Be sure to check your oil frequently - if you have a 5.3 the 07-13 trucks tend to consume a bit of oil due to the first-gen AFM/DOD system being, well, not so great. If it was mine, I'd have a tune installed on the computer to get rid of AFM/DOD. If you have a 4.3 or 4.8 without AFM ignore this.

As above, if you have a 5.3 liter you probably should use a D1G2 (Dexos oil). Also agree with dogememe on the tune issue.
2011 was, I believe, the first year of the GM dexos spec. As far as having to do anything you certainly don't as you are out of warranty. If it is a cost issue, I'd rather have something like Supertech D1G2 in the crankcase than a conventional if I am dealing with the GM AFM system. If you have AFM you will want to keep things as clean as possible or you're likely going to have an oil burner on your hands. If you aren't dealing with the AFM you can run about anything in the regular GM LS engines. They are extremely easy on oil and will run forever.

Most likely wouldnt matter, but not sure of your reason?
Dexos oil is $3.25 a quart in Walmart unless you dont change your own oil, but yeah, agree with the post above, you can use any 5w30 oil, I use conventional 5w30 in everything..
Super Tech Dexos

He has a 4.3 in the Silverado, see accompanying posts. Not sure I'd go 10K if the truck gets used but no reason not to use Dexos oil.

You can stop now because you advice is just as good as a wooden nickel. Not useless both pretty close.

Yes you may its a very low output port injected engine. Nothing a SN+ PCMO can easily handle for 5K.

I just never concerned myself with the dexos thing and my GM vehicles. My 2013 Silverado 5.3, which I was inventing new swear words over for various reasons and traded off for a 2015 Silverado 2500 6.0, I used a Schaeffer 5w30 syn. Not on the "approved" list. My 2015 2500, still very much in warranty, it has been getting a 10w30 syn. Annual oil changes, as I rarely put more than 6000 miles a year on it. My 2006 Caddy came out before the dexos things showed up, but it has only gotten a Pennzoil conventional 10w30 for it's life. 6000-7000 mile oil changes. GM said it required Mobil 1 5w30. The engine never got the memo that the Pennzoil was "substandard". That 3.6 is noted for timing chain issues. This one has never had a major repair of any kind and runs great.
Nothing against dexos spec. I just don't suffer from an enlarged paranoia gland that makes me lose sleep by not using it. I pay attention to the current overall industry standards of SAE and ILSAC. Individual OEM wants and desires rarely play into it. That is also what I do with my commercial heavy trucks. I only concern myself with the latest HDEO specs, not OEM hysteria. Every heavy truck I have owned has gone well over 1 million miles without a major engine or fuel system repair. Current one has 920,000 miles on it. The 2006 Cadillac is still going strong, in very good overall shape, and no desire to get rid of it any time soon.
Use a "approved" oil if one wants to. I am not advocating that anyone not use it. I have more important things in life to worry about. I think some might just need to lighten up also.

Because in this engine there is nothing to gain using synthetic over conventional for a 5K OCI.

my buddy has a 2011 chevy 1500 with the 4.8 bought new, it now has 175k miles, I've been doing his oil changes since it had 40k miles, and I've used pretty much every brand of synthetic 10W30, rarely a 5W30 and even rarer a Dexos 5W30, with zero issues. I change it every 6-7k and it runs flawlessly. For the 2011 model year Dexos was recommended in the owners manual, it wasnt required. It does not even say Dexos on the oil cap, just 5W30.
It runs real quiet on Mobil 1 High Mileage 10w30, this upcoming oil change I'll use Mobil 1 Turbo Diesel Truck 5W40 and let the OLM hit 10%

Would you please expand on this? Dying to find out the reason behind a conventional being as good or better than synthetic oil.

Because conventional does not cokes piston rings especially when not stressed such as this example. It will not be anymore stressed at 5K in this application versus a "synthetic" at 10K. There is no more "conventional" anymore then "synthetic". Both are blends for example "conventional" Pennzoil compared to Pennzoil Platinum has a higher flashpoint and similar NOACK the point were synthetic shines is -42C. I don't recall the recommendation being for Antarctica.

I'll have to look at my oil cap, it does say Dexos in the owner's manual. I went ahead and bought the Supertech 5w30 full synthetic for 15.98, I'm a short trip driver. My OLM is at 42% at 2,400 miles (5 months) so I think the Chevy OLM system is accurate.

You'll be totally fine with the Super Tech Syn. I didn't realize when I first posted that you had the 4.3 V6. Honestly you are going to be fine with that engine as long as you use a quality oil, conventional or synthetic. It should run forever with proper maintenance. You have one of the good ones.

Not only that ^^^ but the conventional might actually give better wear numbers.
Something that seems to be overlooked in the Syn vs Conv posts.
