National Biodiesel Day – March 18, 2025

You can appear smart, eco-friendly, and resourceful to friends, family, and co-workers by celebrating National Biodiesel Day with them this March 18. No doubt they will be impressed with your mad gas knowledge (and so we’re clear, we’re talking about the gas that will help you attract friends, not scare them away). So, let’s kick it biodiesel style!

National Biodiesel Day timeline

1890
Rudolph Diesel Invents the Diesel Engine

What are the odds that he would also create something with the same name as him?

1937
Patented Palm Oil

G. Chavanne is granted a patent for an ethyl ester of palm oil - known as Biodiesel today.

1996
Pacific Biodiesel

This biodiesel production plant was on Maui — the island, not the character in the Disney movie “Moana.”

2005
Worldwide Biodiesel Production Reaches 1.1 Billion Gallons

For the math-impaired, that amounts to quite a lot.

National Biodiesel Day Activities

  1. Watch Josh Tickell's movie "FUEL"

    In this documentary, environmental activist and filmmaker Josh Tickell explores alternative energy sources, especially biofuels, as a way for America to break free of its dependence on foreign oil. If you’re more interested in movies with “stars” in them, it’s worth mentioning that Larry Hagman, Richard Branson, Willie Nelson, Sheryl Crow, and Woody Harrelson all make appearances!

  2. Watch the film, Diesel

    You’ve used his fuel, now see the dramatic recreation of Rudolf Diesel’s life in this 1942 German biographical film. If you don’t speak German, turn on the subtitles.

  3. Eat some French Fries

    It’s actually possible to take used vegetable oil, which is used to make French fries and other delicious fried foods, and recycle it into environmentally friendly biodiesel. While you shouldn’t try doing this at home, having some fries to salute the gas the drives the world is a yummy option.

Why We Love National Biodiesel Day

  1. Because Daryl Hannah is a fan

    In an interview with Sustainable Style Foundation, actress Daryl Hannah said she uses biodiesel to fuel her 1983 Chevy El Camino. “It gets us off of our dependency on fossil fuels and foreign oil as well so we don’t have to go to war for oil," she explained. In short, make biodiesel, not war.

  2. It’s like Starbucks coffee of fuel

    Trucks, tractors, boats, shipping equipment, irrigation systems, mining equipment, electrical generators, diesel-powered cars and all the many systems that use diesel also enjoy a Venti-sized order of biodiesel to make them go. We’re more reliant on biodiesel fuel than we realize, so why not dedicate March 18 to show your appreciation?

  3. Because it’s also Rudolf Diesels’s Birthday

    Rudolf Diesel was an inventor and mechanical engineer who created the diesel engine. He also happened to disappear in 1913 and was found dead under mysterious circumstances. There’s no better time to salute the man whose invention led to engines that power agricultural machines, submarines, ships, and much later, locomotives, trucks, and many modern automobiles.
