It's been 0 or less this week and my truck keeps freezing up. I put winter flow in the first tank then a quart of red alert in the second tank yet I still have to keep putting the bullet heater to it to get it running. Should I siphon the tank and start with fresh fuel. I already replaced the stock fuel filter twice. Patience is getting thin. Guy at the fuel station says they can't figure out the correct blend for winter use. Is it possible to have alot of ice in the tank without the water light going off.
