Just because something is considered "synthetic" (group IV/V according to your definition), it doesn't automatically mean it's a great product. Additive package can make a huge difference, for example. There are some weak group IV/V oils out there, and there are also some outstanding group III/III+ oils out there, too. If you'd rather put your money on the word "synthetic" instead of specific mfg specs that determine the oil's actual performance, you can certainly do so, but it is "old fashioned" indeed. We here at BITOG (well, some of us at least) believe in buying a certain level of performance and not a jar of specific ingredients that may or may not add up to something good.
Well, seeing as my truck is no longer under warranty, and the only spec my OM calls out is the anemic GM6094M, I believe the LM Vollsynthese[SM] will work.
