Hope this helps.

Um, don't the oil weights behave the same at different temperatures? IE, a 10W30 sythentic vs regular will flow the same at -25? If synthetic didn't "thicken" until -50, then it wouldn't be a 10W30. It's the weight of the oil that matters when it comes to viscosity and temperature, not the type of oil. I call BS on your post.
As for the OP... yes, get a block heater. It's only useful a handful of days in the winter, but you'll thank god you have it during those days.
