Picked up 5 qts of Red Line High Performance 5W40 as I'm due for a change soon. Curious if anyone has run this in winter? I know the specs and everything say it's fine but with our finicky EJs thought I'd ask for firsthand experience.

If anyone cares, decided to stick to Castrol Edge 0W40. It's performing beautifully, and with all oil leaks fixed no reason to look for anything else. Plan was to run Red Line in the summer after installing a pressure gauge but scrapping that.
