With the current weather I'm just curious if Castrol Edge 0W30 is any good for cold starts in freezing temperatures, and generally what makes an oil "good" for cold starts?
As always a google search brings up many conflicting results.

My small understanding of oil ratings is the W rating is the viscosity when cold (W for winter), the lower the number the lower the cold viscosity is, ie. better for cold starts.Quote:
