I won't bother watching - it will be the same old arguments about synthetic oil versus dino rehashed.
Point is, modern mineral oils are evidently more than good enough, as evidenced by the DEXOS specifications reaching to semi or fully conventional oils.
Here in Australia, mineral ACEA A3/B4 oils are par for the course - that's your long drain, high detergency oil suitable for many Euro vehicles.
Truckers? Last I heard, mineral oils were still the go-to due to the cost of synthetic oils.
If you don't live in a climate where temperatures reach zero, do the minute "wear savings" from synthetic REALLY make a difference? I'd say no - by the time you get to 300,000km (about 200K miles), the engine will be the least of worries for the intrepid motorist.
