So exactly how bad is 20w-50...

in temps as low as 10F? I live in NW Arkansas, and that is as cold as it gets, usually hovering from 20-40 daytime lows-highs in Dec-Early Feb.

Am I killing this engine (and all the others I do that to) by doing that? I always give 5-10 min to warm the engine.

Also, I just noticed that I have a block heater. Would that help in cold conditions (ie not harm it with running 20w-50)?

Thanks for any help.
