I have seen the T6 at Walmart and it was cheaper than the Platinum but I always thought it was for Trucks or pickups and not to be used in a GM 6 Cylinder Impala. Would like to know your thoughts about this please.
Wouldn't say it's cheaper because it's in 4 quart (1 gal) jugs, whereas the PPPP is in a 5 quart.
But, current version T6 can be used in your Impala (now it might be the best choice) , it's dual rated. I occasionally use it in my Jetta.
