He's in CT, if he really is concerned about easy (
of shifting when it is 30 or below he may want to use Royal Purple. I have used it and found that the shifting is noticably easier than with Redline MTL. I'm using MTL now. The last few mornings it was between 8-13°F, my car was parked outside in the hotel lot. It didn't shift that well for the first 5-6 miles. After that it was fine.
