Blending

Biodiesel fuel can be blended at any level with petroleum diesel to create a biodiesel blend.

The chart below shows the refining process of a typical barrel of crude oil.

A barrel of petroleum break-down

• 50% gasoline
• 8% diesel
• 42% propane/propylene ECT

Most Common Blends

There are two main types of biodiesel fuel on the market (with various percentage blends in between):

B100 – 100% pure biodiesel fuel (“Neat” Biodiesel)
B20 – 20% biodiesel and 80% petroleum diesel

While the first (pure) option may require certain engine modifications to run smoothly, the second (blended) option does not. Lower levels of biodiesel (1-3%) are used to add lubricity to petrodiesel.

Blending occurs en route between pickup and delivery:

• As the tanker is filled at two separate terminals
• As the tanker stops at a “frack” tank located near a petroleum terminal
• As the tanker visits a “frack” tank strategically located centrally to truck stops
