Guess I'll just stick to straight Valvoline 30 for warmer weather. Actually since it doesn't get below 60 when I actually use the car I could leave that in year round. Was mostly wondering how low you go in the frigid East.

Back in the 60s STP was experimented with for things such as gearbox woes and tons more applications so there is probably something to the Redline thing.
