What are my options if I want to use Biodiesel in cold weather?
To use Biodiesel in cold temperatures you can blend it with petroleum diesel, so that you have no more than 15% to 20% Biodiesel in your mixture. In this case, the cold-filter plug point of the petroleum diesel remains unaffected by the added Biodiesel, but you will still need to use an additive to prevent gelling. If you want to run Biodiesel in higher percentages in cold temperatures, you could adapt your vehicle fuel system to allow it to heat the Biodiesel above the cold-filter plug point. There are a variety of ways this can be done. Please do adequate research before making any adaptations to your vehicles fuel system.
