No need to. I did switch from Mobil 1 to Castrol Edge in my 1998 Corvette. I did not like the high lead readings I was getting. Edge cut them by 3 times !
Also switched from Mobil 1 to Pennzoil Platinum in my other cars.
I still think Mobil 1 is a good oil, there are just some better now.

Great answer. Now get yourself a used oil analysis and try different oils and see which one works the best in your app.
