As long as the oil meets or exceeds their spec. and most do they can not void your warranty. Any full synthetic exceeds their spec. unless your buying joe crackhead recycled oil you will be fine.

OK:
1) Dexos is a certification, not a designation of any certain brand.
2) "Lowest bidder, semi-synthetic," not true. For example, I've seen a lot of "synthetic" oil brands with the Dexos certification. Are you implying that oil labeled as "synthetic" isn't truly as advertised, by chance?
3) Select an oil that "exceeds" the Dexos spec, eh? So what if it contains compounds/elements that destroy the catalytic converters? As if that's not expensive. And it's warranty-voiding.
Senor Cunningham, you've made some good posts on here in the past, but I'm not buying this one.
