The synthetic is fine. It's thinner at -37 than the 10W & 5w30 mineral oil. The oil pan heater makes it a mute point anyways. Tell the old timers to quit living in the past.
If she won't start without either in the summer the heat from compression is low and the injection system likely not breaking the fuel into a fine enough mist.
Low compression in "rebuilt" diesels occurs when just rings are installed on pistons with worn ring grooves, out of round oversize cylinder walls, sunk valves from grinding seats and valves rathe rathan replacement. The injectors are likely spraying through worn/plugged tips before rated pressure is being reached. Cranking speed maybe too slow as well.
