..... Add it all up and the difference between 30*F and 0*F is a lot greater than the difference between 60*F and 30*F.
A better temperature range would be 90* to 20*. That would account for 95% of my driving, and even at 20* the engine has only a slightly harder time on start-up than usual.
All I wanted to get across was that T6 can be used in an N/A subie. Of course if you live where it's really cold, like subzero frequently, T6 wouldn't be ideal to use.
