Hi guys, well it seems that I want to run a 0w30 oil in my 2009 gmc sierra 5.3 with afm, my truck has 33xxx miles on her and she isn't burning oil. I was leaning towards m1 0w 30 but I've read here on bitog that its not that great of an oil especially since at start up its not much thinner than most synthetic 5w30s, so please shoot me recommendations, also take into account that I plan on doing 5k mile oci's and I want an oil that is easy to come by.
