Generally speaking, synthetic oils are superior to conventional oils.
But at 117K, what's the benefit in switching? To the extent dino hasn't been protecting the engine, much of the wear has already occurred. There's also the anecdotal evidence of many who have switched only to find that the synthetic finds leak paths that weren't there before.
That said, I'm a fan of synthetics, and if you are as well, then try it. If leaks develop you can always go back to dino. Pick a good brand with the correct viscosity per your manual.
Edit: Mobil1's site recommends their 0W40.
