Nonsense; we have been using 10W-40 Castrol Syntec in customer cars for a long time and it gets plenty cold here as well. And, when you look back a few years, 10W oil was the recommended grade for arctic conditions, so why should it be a problem now?.

I never could justify the OEM rationale for 0W – anything, especially considering how poorly their “chosen” oil performs in used oil analysis after mild usage and low mileage conditions………..

By-the-by; to get back on point, I’ve noticed Wal-Mart in our area selling the 10W-40 Syntec for about $22 for a five quart container……….
