Frequently Asked Questions


Yes you can produce your own biodiesel and do it safely. Be forewarned that making biodiesel is not for everybody. It takes some commitment, a small investment, time, and garage space. Houston Biodiesel has over the years hosted dozens of biodiesel workshops. Of late we've gotten away from the workshops although we still support the home brewer. If you need guidance you can hire use for some one-on-one instruction. We also have for sale some key ingredients needed to produce biodiesel.

Some highlights include: 78% net CO2 reduction, 70% hydrocarbon emission reduction, 40% less carbon monoxide, and 50% less particulate (black smoke), renewable, cleaner burning, better for the engine due to it's higher lubricity and cetane, lower impact on the environment, better for public health, smells better, and locally produced. And sometimes its even less expensive than diesel.

Price (often higher), location, and cold weather. Biodiesel is a commodity and the price fluctuates compared to diesel. Finding a good reliable B100 retailer can sometimes be difficult. Biodiesel gels (or freezes) at a higher temperature than diesel. So in a cold climate you may find running B100 is not possible. Even in Houston we recommend biodiesel users blend with diesel October through April. In colder climates you must blend B100 with diesel to lower the overall gel point. If you burn biodiesel in an older vehicle you'll possibly produce higher Nox emissions.

A man ahead of his time and the inventor of the successful Diesel engine. Our hero.

B refers to biodiesel and the number refers to the percentage of biodiesel in the blend. Hence, B20 is 20% biodiesel and 80% petrol diesel. Simple right?

Biodiesel is a commodity and fluctuates with the market. The price is usually comparable to petroleum diesel.

Yes, if it's a diesel than it will work! Biodiesel will work in any compression ignition engine with no modifications. That's the whole point of biodiesel. Just pour it into your tank and drive. NO MODIFICATIONS!

Biodiesel or B100 is a renewable fuel. It produces fewer overall emissions than diesel. It has a much higher cetane and offers superior lubricity over diesel fuel. Biodiesel can be produced from any fat either vegetable or animal.

While your engine is happy to burn straight vegetable oil (SVO) your diesel fuel system was designed to handle petroleum diesel and not straight vegetable oil. Think of biodiesel as a slightly modified vegetable oil that works in your diesel engine without any modifications. The idea behind biodiesel is to modify the vegetable oil and NOT your vehicle.
