The National Biodiesel Board states that biodiesel blends of 20% (B20) and below will work in any diesel engine without needing modifications, and that the blends will work just like petroleum diesel.

The NBB also recommends the following precautions:

  • Make sure to by B20 from a reputable source.
  • Buy fuel that has already been blended.
  • Do not buy from someone who makes fuel in their garage or backyard.
