I have had a 2014 and now a 2015,,, both with the 5.3 EcoTec motor,,,,,have had so many different opinions on how much oil this engine takes, is it 8 quarts or 8 1/2? And is it Full Synthetic or a Blend? I will probably get mixed answers here also,,,thanks for the help on this topic!

Z15, oil weight, yes. But he's questioning how much oil it takes and if it requires a full synthetic or a synthetic blend. Neither of which are on the cap.

Note - Full synthetic is not required...the only requirement is the oil meet dexos1 or equivalent.

My 2015 says 8.5 qts in the manual. Did your truck not come with one? Chevy also has the manual for all model years in PDF form on their website.
It was listed as 8.5 qts in the OM; then GM released the aforementioned bulletin which states to use 8 qts.
I know the OP may want to know for other reasons, but in reality, it takes as much oil as is required to get it to the top of fill range on the dip stick.
According to GM, they recommend DEXOS1 certified oil but there are a lot of oils that are DEXOS1 complient, yet don't sport the Dexos logo and are not officially certified by GM. Regardless, the oil necessary for your truck should be either semi-synthetic or full synthetic as there are no conventional oils meeting the Dexos1 Specs.

For a dexos1 0w20 full synthetic oil, I would seriously look at the Quaker State Ultimate Durability 0w20. It is on the approved dexos1 list and from the Petroleum Quality Institute of America analysis, it is a killer oil with a VERY stout additive package. I don't use a 0w20, but this all got me interested and I did some checking. If I had to choose a solid oil that meets the specs and probably can be had at a reasonable price in most locations, and even on sale from time to time, I would look no further than the QSUD 0w20. It put the Mobil 1 to shame!
Here was a comparison to some other oils done by PQIA....

Blew everything else away in Calcium level. That is a detergent item and makes up the lion's share of the TBN component. TBN controls acids from combustion. Calcium is the primary component to do that. Think of it as Tums for your motor. It is also rich in moly, which is a very good thing. Not sure how that means anything? Here is a set of articles on the benefit of moly in motor oils. All the oils I use have healthy levels of moly in them. With these AFM motors, moly is a great addition to help prevent problems.
