Modern specs have gotten more robust, this means synthetics too. But the oil temps seen in some vehicles means that a more oxidation-resistant lube is necessary. Grp III and III+ are likely more than good enough with the right chemistry add packs, but II+ and below likely aren't, so that would be my concern.

Time at temperature = oxidation and degradation.

Also, one would have to find the appropriate spec, such as ACEA A3, which is not easy to find in a typical viscosity conventional.

I'm actually amazed that ALL the newer turbo econo and mid size cars haven't had more engine/turbo failures when running regular oil. I mean, regardless of the technology of these newer cars, they run much hotter and are under a lot of stress that their NA predecessors weren't. I'd be interested to see how they stand the test of time.

I remember in the early 80's with Saab and Volvo being the major users of turbo's on gasser engines, these turbo setups would usually last about 100k miles then a new turbo was in order, regardless of how much you maintained them.

There is no problem per se running a conventional motor oil if shorter oil change intervals are maintained but the motivation to use a dino is initial cost savings and no one is thinking it through that a shorter OCI may be required.
What is most likely is that those going cheap on using a Dino are more likely to not check the oil level and will delay having the oil changed as required.

Unless of course the motor was designed and engineered around synthetic oil, as Doug Hillary has alluded to...
