[s-cars] Winter weight oil recommendations, temporarily seized brake caliper.....

[Larry]

Well -5 F isn't too common by me, when it has happened, the car crankily started fine with 10W-30 Mobil 1, so I doubt it is your 0W-40 causing the problem (most certainly your oil was at 0 on the viscosity scale that temp), I'd bet your battery is getting weak, or you have corrosion at the terminals or the dreaded splice. Easiest to test the battery first.

Temp was somewhere in the -5F range.  After a space heater under the iol pan, she started fine.....I'm due for an oil change anyway, and usually run 0-W40 synthetic year round with no troubles.  Question is, does the fact that I'm at the end of the oil change cycle contribute to the added thickness of the oil, or should I consider something thinner as far as oil goes?  I tend to drive spiritedly, so I need to heat protection on the upper end.  Thoughts?  My garage isn't insulated or heated.....
