by Bethany Baratta (Iowa Soybean Association) Dave Walton relies on biodiesel to power his tractors and machinery year-round. The farmer from Wilton likes biodiesel because of its dependability and increased lubricity. It’s also a homegrown product, made primarily from soybeans like those grown on his eastern Iowa farm.

Walton also appreciates that it’s cleaner burning compared to diesel.

Like all other fuel uses in the winter, general fuel and tank maintenance are important to using biodiesel blends effectively.

“The key is making sure the fuel is clean coming out of the tank,” says Walton, board treasurer for the Iowa Soybean Association and member of the Iowa Biodiesel and National Biodiesel Boards. Filters and traps help ensure cleaner fuel, which improves operability.

1: Know Your Fuel

Fuel performance in cold weather can vary based on the crude oil source and how it’s been refined. All diesel fuels contain wax. It will undergo changes, below a specific temperature such as crystallization, gelling or viscosity increase. These changes can reduce the ability of the fuel to flow and create filter plugging concerns, adversely affecting the operability of vehicles.

Two cold-flow measurements are critical: …

2: Use Winter Fuel Additives

Regardless of the fuel you use, it’s important to winterize fuel to withstand expected low temperatures in your area.

…

3: Water is the Enemy

Top off tanks to eliminate air space that could foster condensation when temperatures change. Keep fuel caps tight to keep water from entering the tank. Inspect hoses and gaskets for leaks.

4: Check Your Filters

Install a new 30-micron or higher dispenser filter before winter.
