??????? I'm confused. Your saying that 15-40 is the same as straight 30 when it gets cold. I'm not doubting you but seems to make no sense. Years ago when it was very very cold my brother had his John Deere 4020 plugged in with the water heater and one of these magnet heaters on it. I went over to his house since he was going to go out and move snow. We had a big one. He checked the oil and it was a little low. He used straight 30 for some reason. When he went to pour some in it wouldn't even pour. Not that's thick.
