I've used this stuff for a couple winters (It usually goes on sale just before the winter at Cdn Tire for $2.xx bottle). It works well based solely on noises heard and how easily the engine turns over. This year, since I managed to get PP for dirt cheap, that'll be my winter oil. We'll see how it compares.
I'd use the QS winter again.
