What is biodiesel? A renewable, lower emission, higher cetane, better lubricity diesel engine fuel made from vegetable oil or animal fat. While your engine is happy to burn straight vegetable oil (SVO) your diesel fuel system was designed to pump petroleum diesel and not veggie oil. Biodiesel is modified vegetable oil with a lower viscosity, thus giving biodiesel a similar viscosity to petrol diesel. The idea behind biodiesel is to modify the vegetable oil and NOT your vehicle. No mods necessary to use biodiesel. Your fuel system will not know the difference other than it will get cleaned, engine will run quieter and smoother with less emissions and better smell.
Will biodiesel work in my diesel engine? Yes, if it's a diesel 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!
How much does it cost? Comparable to petroleum diesel.
What is B5, B20, and B100? 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.
Who is Dr. Diesel? A man ahead of his time and the inventor of the successful Diesel engine. Our hero.
What are the drawbacks of using biodiesel? Finding it can sometimes be difficult. Gels at a higher temperature than diesel so in a cold climate you may have gelling problems. Usually a higher cost per gallon. Possibly higher Nox emissions in older vehicles. Eats rubber, but modern vehicles have no rubber in the fuel system.
What are the benefits of using biodiesel? Too many to list. Some highlights: renewable, much cleaner burning, better for the engine and environment and health, SMELLS GOOD, and supports your local economy.
Can I make my own biodiesel? Yes, although it takes some commitment, a small investment, time, and garage space. Suggest you attend one of our classes to find out how to make it safely.
