I use Mobil 1 as well change it once a year. The problem isn’t going to be the mileage. That’s going to be all highway driving. It’s the sitting and not being used that the full synthetic helps. If you can use yours each month that’s great. But for us northerners where they sit for 3 or 4 months out of the year the synthetic adds a little more protection. Or at least I have been told that. Who knows if that’s true but for not really that much more when you do it yourself it’s a feel good at least.
