Good question.
All I know is that I routinely got vehicles to go into the hundreds of thousands of miles, all on conventional oil, and all with 6,000 mile OCIs, and Wix filters before ADBVs became the norm. High ZDDP didn't save the cams. Conventional didn't sludge the engines. Synthetic would have cost me much more, and the spread between conventional and synthetic prices was much more pronounced back then.
The taxi owners who did have problems were the ones who messed around with the basics of maintenance. They, just like everyone else, would claim they changed every 3,000 miles, yet their oils was black and had the consistency of tar, and low on the dipstick. Or they'd never maintain anything else that could affect the oil and lubrication, including the PCV or fueling. And the few guys that did try synthetic didn't have a clue as to how to maintain an engine in the first place, and all that did was buy themselves a bit of time.
I've used synthetic, too, and think it's a great product. However, unless the vehicle is speced for it (or has some overriding reason to use it) or the OCIs are being extended, I think it's a waste of money. As I've mentioned before, my G is under warranty, and I am not using synthetic for 3750 mile OCIs. So, synthetics are out until at least warranty is done. As for my old truck, with a carb, I'm not particularly enthused about diluting expensive synthetic with gasoline, either.
