Certainly SAE15W-40 is too heavy for those temperatures, check y0ur owners manual for a proper recommendation, probably straight SAE10W. Your dipstick is a straight line right into the oil pan, so an alternative to a block heater is a dipstick heater. Don't know how easy they are to find nowadays, they used to be common items in auto parts and accessory stores.
