Diesel fuel is obtained through the partial distillation of crude oil. It contains mineral compounds and sulfur and is composed primarily of paraffin and napthenic compounds. Diesel is ignited in an internal combustion engine cylinder by the heat of air under high compression. It’s primarily used in heavy-duty vehicles – on-road and off-road trucks, tractors, construction equipment, locomotives and marine engines.

Diesel fuel is very similar to heating oil. In the United States there are taxes on clear diesel fuel that is used on the highway. Off-road applications, primarily agricultural or construction, can use red-dyed fuel that doesn’t include the road tax. This untaxed diesel is dyed red for identification purposes. A person can be fined if they’re using this untaxed diesel fuel for an “on-road” taxable purpose.

BioDiesel can be made from soybean, canola, animal fats, waste vegetable oil or microalgae oils through a process where they are combined with alcohol in the presence of a catalyst to form ethyl or methyl ester. It can be mixed with petroleum diesel and stored anywhere petroleum is. Although it can be blended at any percentage, 2% is the most common for any application. We have 100% soy available which can be blended at whatever percentage a customer may request – for a clear or dyed application.
