My new P/U is a Chev 4.8L. The warranty requires some fancy named oil that GM markets. Nobody will admit to it but I am betting it's at least synthetic blend. So I just go one step farther and use Mobil1 0w-30 since it exceeds the warranty requirements of the funny named 5w-30 required. But I still only change it once a year.
For what it's worth I know their ATF is pure syn and their diff. oil is too. Nowhere in the owners manual is ANY mention of changing either for the life of the maintenance record which I think is 150,000 miles.
However, I live in the country, every trip is at least 7 miles, I drive about 6000 miles per year, don't sit in traffic or pull heavy trailers very often and all that so really I fit in the once per year or 7500 mile upper limits of todays warranties with the better lubricants we have.
