Well, it doesn't look like the dino oil is doing your engine any damage from the numbers perspective, and even if you have to change it more frequently, it will likely end up being cheaper anyways (I'll leave the math to you tho).

And you won't feel like you're wasting synth oil either.

So my vote is go with Dino... unless you feel you want the extra peace of mind...

of course, it might be interesting to see at what point the synth starts breaking down...
