All the above oils are fine, just change it often and use a good quality filter (I use OEM). Do a Blackstone oil sample if you're really wanting true data about the quality of the oil and condition of the engine (metal,fuel,additive, and coolant content).
I use Amsoil. I have never sent it off for an oil sample on my Viper , but I have on my daily driven SRT8 Jeep. I ran the oil 10K miles and the last sample came back with excellent results and below average wear. The average miles tested for that vehicle were only 4400 miles vs my 10k miles. They actually suggested I run it for 12K miles before changing it.
