Synthetic oils flow better at cold temps, and have better high temp breakdown resistance. So they are a better oil. But all engine oils do get contaminated and the additive packages break down; that is ultimately why you do need to fully change the oil and filter at some interval, not to exceed mfr's recommendations. You can do it sooner, certainly won't hurt and new oil change is relatively cheap. Especially if you DIY.
I have several old cars that don't get a lot of miles. I do not change oil each year. But they also are stored inside a temp controlled garage so do not get the condensation issues like stored outside. Couple of my old cars don't even have oil filters!
There is nothing wrong with dino oil, in fact most labeled synthetics are really just extra refined dino oils and have extra additive packages. But synthetic oil is generally a better product on an equal comparison basis.
