Place me in the synthetic camp, Mobil 1 for all my vehicles for, oh, 35 years. My experience and research leads me to the opinion that good synthetics cut engine wear by roughly a factor of ten. I even use Mobil 1 in my lawnmower...

The research referred to involved oil analysis at short intervals (on a modern car admittedly) to look at the levels of wear metals present in the oil. This was a crowd-funded independent project tragically cut short by the death of the project instigator in a car crash.

If you ever get the chance, compare the internals of a torn-down engine run on syn and one run on 'dino" oil. It's an eye-opener.

All that being said, I'm not brave enough to put syn oil in my A, as it hasn't been rebuilt in at least half a century. If I ever have it rebuilt to modern standards, with insert bearings and modern seals, it'll be run on synthetic for sure.
