Why, yes I did. I'm gratified you're sophisticated enough to notice :)
1. Synthetic oils are awesome.
2. Using them in old Mopars, without rebuilding the engine will result in headaches you don't want to deal with. Most synthetics will cause the old seals, which have lived in dino oil for years, to either shrink or swell. In the rare "swell" cases, the seals just plain fall apart and it's c atastrophic failure.
In much of the rest of effects, the seals shrink slightly, become extremely brittle and break.
(i have been through more than one episode of this in my own rigs over the years, call me 'experienced'.)
