Your vehicle so use whatever makes you happy. If that is Dexos use it. Just be aware you are perfectly safe using an API Starburst certified oil as well. Both mechanically in the vehicle and legality wise with your warranty. I base that on YEARS of experience with this stuff( I worked dealer service among other jobs in the auto field and have dealt with this stuff a lot ). If the owner's manual says you can use API Starburst in place of Dexos, and you do and have an engine issue, GM can NOT say you used the wrong oil to get out of it. Now, they may TRY but no way they win and I doubt they even try based JUST on not using the Dexos.
Unless they can show they added an addendum to the manual striking that API Staruburst clause and they can also show you received it they have no leg to stand on regardless of how much a Judge does or does not know about oil. You were given an owner's manual with the vehicle by the car mfg when purchased that tells you what is and is not allowed. It is what they have told you to do. It doesn't matter what the cap says if the manual allows for something else to be used. It is similar to the fuel recommendations for my truck in the owner's manual. 89 octane is preferred but 87 octane is acceptable. It isn't exactly the same thing but it is close enough to use as an example.
If your wife is any kind of lawyer at all( that is not meant offensive - just a comment )she would easily win such a case if it ever came up. I seriously doubt it would. She can justify the use of API Starburst oil by the car mfg's own words in the owner's manual saying it is ok to use. She can also bring up the fact that the 2010 Equinox with the same Ecotec 4cyl was spec'd for API Starburst oil as Dexos was not out. The ONLY change to that engine in the Equinox from 2010 to 2011 was the oil spec. No mechanical changes requiring the change just a new spec from the mfg being used.
GM would have absolutely nothing to win on. Now, I am not trying to talk you out of or into using anything. Just want you to be aware of what you can do. You seem to feel you are forced to use Dexos and you are not. You acknowledge the owner's manual info but seem to think it means nothing. I don't get it?
If GM was going to hassle people on warranty claims for using API Starburst oil they would not say in the manual it can be used as needed. If it would hurt anything they would put comments in there about change the oil as soon as you can get some Dexos or if using API Starburst oil in place of Dexos reduce your OCI. No such warnings are there because NOTHING is going to happen using either oil type.
Best of luck with whatever oil you go with.
