Correct. And since GM doesn't REQUIRE the use of Dexos oils, they simply recommend it, they cannot deny warranty if you don't use it. This is quite different from a lot of Ford's verbiage stating that you must use an oil meeting WSS-xxxxxxx and that of many of the Euro marques that REQUIRE you to use an oil that is approved by them (and hence their approval lists).
